The published version of that index is formally known as the Louisiana Spatial Data Index (LSDX). These data (provided both online and represented within this document) constitute the Louisiana Spatial Data Infrastructure (LSDI), a collection of critical geospatial data assets for Louisiana. About the Louisiana Spatial Data Index (LSDX): The Louisiana Spatial Data Index (LSDX) is an inventory of cataloged geospatial data assets utilized by the Louisiana geospatial community (i.e. academic, commercial, private, and public professionals). The data listed within this document consists of the most current information available describing the data assets. Descriptions were compiled from the metadata records maintained by the data contributors and/or custodians. For more detailed description of any of the data layers, including disclaimers and intended use, users are encouraged to review the complete metadata records provided with each dataset. About Louisiana's Geospatial Framework Data Structure The Louisiana geospatial framework data initiative is a collaborative effort of the Louisiana Geographic Information Systems Council (LGISC) and the LAGIC, and is intended to serve as a publically accessible source of basic geographic data for Louisiana (e.g. customizable base maps of the State). The data maintained within the LSDI includes several geospatial framework data layers (or themes) that represent the most common data themes used within Louisiana. The goals of the LSDI and framework initiative is to improve geospatial operations and analysis, reduce costs, and facilitate joint decision making by providing a readily available set of basic digital geographic data. The framework consists of commonly needed, used, and produced data assembled according to published data standards. The LSDI and framework initiative also represents the foundations for a collaborative development environment in which geospatial data stakeholders create and use of these data. The LSDI and framework data structure comprise a collection of key components: •
•
•
•
Seven federally designated digital geographic data themes that are commonly employed within the United States; Eight state designated digital geospatial data themes that are commonly employed within Louisiana; Procedures, standards, and guidelines that provide for integration, sharing, and utilization of these data; and Collaborative relationships within the geospatial community that provide business practices which encourage the continued development and maintenance framework data. These fifteen framework data themes are represented in Figure 1 (below). x The data cataloged in this document represents the best available, publically accessible geospatial framework data layers for Louisiana. These data have been collected and disseminated by LAGIC on behalf of the Louisiana GIS Council. Every effort is made to ensure that these data layers follow published data standards and guidelines. In no way is this listing complete. What's more, many of the data cataloged within this document may legitimately be categorized in more than one of the fifteen data themes. Never the less, the LSDI framework provides a foundation upon which Louisiana geospatial data stakeholders and users can build ‐ by adding their own attributes and compiling other data sets. Figure 1: Louisiana Geospatial Framework Data Layers Goals of the LSDI and Geospatial Framework Initiative The LSDI and geospatial framework environment is designed to be responsive to the needs of all of the State's geographic data community. The Louisiana geographic data user community consists of many different, and sometimes unexpected disciplines. Yet regardless of their field, each user/consumer/developer share the common, recurring need for seven basic geospatial data themes: •
•
cadastral elevation & bathymetry xi •
•
•
•
•
geodetic control governmental units hydrography imagery transportation And as depicted earlier in Figure 1, Louisiana has expanded this basic thematic collection to include eight additional themes that are critical to Louisiana: • biologic • cultural • economic • environmental • geophysical • infrastructure • land use & land cover • map reference Many organizations produce and use these data themes every day. As such, the framework represents the common base map on which organizations develop and deploy geographically enabled applications. By attaching their own geographic data to the common data framework, users develop spatial applications more easily and at less cost. In short, these fifteen data themes provide: •
•
•
•
collection of data that can be used in nearly any geo‐spatial application, a standardized base map on which users can add or attach geographic details and attributes, a reference source for accurately registered and compiled data sets, and a common reference map for displaying application specific and/or custom analytical output. It is important to note that the framework is a growing resource to which geographic data producers can contribute. As such, it will continually evolve and improve. To that end, the framework also includes procedures, guidelines, and standards that enable and assist participants to build, integrate, maintain, distribute, and use these framework data: •
•
•
users can depend on accurate, detailed data that can be certified and integrated into the framework to create a trustworthy data source; users can update their data holdings from the framework data; and users can attach additional information to the framework. Finally, the framework encourages institutional relationships and business practices that ensure that framework data are created, maintained, and distributed for all geographic areas and that widespread use is encouraged. The framework integrates data from all types of organizations in all sectors, promotes partnerships for data creation and maintenance, and provides unrestricted access to data. xii LSDI Guiding Principles The following are the guiding principles for building the LSDI framework: •
•
•
•
•
The preferred data source. Framework layers should represent the best available, publically accessible data for Louisiana ‐‐ the most current, complete, and accurate data. A standards based data source. Users must be able to easily integrate framework data with their own and provide feedback and corrections to framework data. An accessible data source for the geospatial community. Access to framework data should be at the lowest possible cost, and without restrictions on use and dissemination. The framework is a public resource. Promotes interoperability and elimination of redundancy. Sharing the development and maintenance of framework data reduces the costs of individual users' data production. The framework should be based on cooperation. It is built through the combined efforts of many participants who work together on its design and development and contribute data to it. Data Organization The data presented within this document is organized according to framework data theme. The feature classes are sorted alphabetically according to its published title. Data descriptions include a thumbnail browse graphic, metadata description, year of publication, data custodian/publisher, downloadable link, geographic extents, and metadata link. In most cases, the data were assigned one, or more, of the fifteen (both Federal and State designated) Framework categories and/or keywords. In most cases, thematic designations were assigned by the data custodian/provider. For all other instances, the Louisiana Oil Spill Coordinator's Office (LOSCO) Technical Application Program assigned values for those feature classes for the purpose of data organization on the 2007 Louisiana GIS Data DVD‐ROM. See this link: http://lagic.lsu.edu/geodata/LOSCO/2007_DVD/default_2007DVD.htm. For the vast majority of the data, the Framework assignments for each of the feature classes is intuitive. However, there are some assignments that are open to interpretation. Every effort has been made to maintain the thematic classification of the data layer submitted to the LAGIC. Accordingly, users are encouraged to contact the data provider/custodian if a re‐classification is in order. Update frequency The Louisiana Spatial Data Index (LSDX) will be published no less than once per year. For the latest updates, users are encouraged to visit the LAGIC Geodata web site: http://lagic.lsu.edu/geodata/. xiii Biologic Feature Classes Introduction Biologic feature classes commonly include spatially referenced information of non‐human biological resources, systems, and phenomena that include plants, animals, and ecological systems. Examples of biological data include habitat areas, ecosystems, fisheries and aquatics, forestry, wildlife preserves, vegetation, organism (subspecies, species, and systematic), and ecological (populations, communities, ecosystems, biomes, etc.) levels. Applications of Biological data include conservation, bio‐diversity surveys, species management, and more. Maintained Data Layers The following Biological data layers are maintained by LAGIC.

2 Louisiana Coastal Marsh Vegetative Type (points) Description: This data set contains vector point information. The original data set was collected through visual field observation by Greg Linscombe of LDWF and Robert H. Chabreck of LSU Agricultural Center. The observations were made while flying over the study areas (Louisiana Coastal Zone) in a Bell 206 Jet Ranger helicopter. Flight was along north/south transects spaced 1.87 miles apart from the Texas state line to the Mississippi state line. Vegetative data was obtained at pre‐determined stations spaced at 0.5 miles along each transect. The stations were located using a Trimble Ag 122 Global Positioning system (GPS) and a computer running GPSView by Geowarehouse. This information was recorded manually into field tally sheets and later was entered into a Microsoft Access Database. At this point, this information was brought into a GIS application by converting the file to database format (dbf). A GIS software application was utilized to generate the points along the transect routes. The flight line data was used as a guide to generate the points along the transect routes. The data points produced were used as a guide for the production of marsh type delineation lines. The new data set resulted in a point coverage containing vegetative marsh type attributes along transect flight lines. Coverage is of the coastal region of the State of Louisiana.

This information was recorded manually into field tally sheets and later this information was entered into a Microsoft Access database. At this point, this information was brought into a GIS application by converting the file to a database format (dbf). The marsh type delineation lines were produced by freehanding contours through on‐screen interpretation. The flight line data was used as a guide for drawing the lines. The new data set resulted in a line coverage delineating vegetative marsh types. Coverage is of the coastal region of the State of Louisiana. [] 2001 Published:

6 Cadastral Feature Classes Introduction Cadastral information typically refers to property interests and other descriptions of real property. Cadastral data represent the geographic extent of the past, current, and future rights and interests in real property. The spatial information necessary to describe the geographic extent and the rights and interests includes surveys, legal description reference systems, and parcel‐by‐parcel surveys and descriptions. The primary aspect of cadastral information within the spatial data framework is the cadastral reference systems. Examples of this framework layer include the Public Land Survey System (PLSS) and similar systems. Features include the survey corner, survey boundary, and parcel. Each instance of a feature has the attributes of name (or other common identifier) and information about data quality. Each instance also should have a permanent feature identification code. For the PLSS, the minimum content is the boundaries of sections, including deflection points and the positions for quarter corners along section boundaries. Boundaries that have been surveyed are the preferred content for cadastral reference systems. Cadastral information is the basis of many analytical, decision‐making, and operational applications, including site selection, land use administration, and transportation planning. The PLSS reference system is often used to register locally produced information into the framework. Information about publicly owned lands serves both those who administer the lands and those who have interests in them ‐‐ an especially popular topic for the sportsmen and sprotswomen of Louisiana. Framework representation of these lands provides useful information about their location, boundaries, extent, and relationships to other geographic features and phenomena. Because parcels play an important role in many public and private sector activities, and parcel information is a basic ingredient of many applications, there is interest in providing multiple levels of cadastral data. These levels would be based on available data and customer requirements. The framework provides a means to link existing parcel data into the larger cadastral network.

Oyster leases in Louisiana Description: This data set indicates the locations of
oyster leases in Louisiana. The lease areas
should be polygons, however, the source
data has very poor topology including
many 'polygons' which do not close and
polygons which overlap. Additionally,
adjacent polygons do not always share a
side, but appear to replicate it without
exact overlap (there are frequent gaps
between polygons). It is not always clear if
these gaps are just errors in the geometric
description of the lease areas or represent
unleased channels between the leases. For
these reasons, the coverage has only been
built as a line coverage. There are no
useful attributes or labeling associated with
the lease areas. The attributes that are
associated with the data are a result of the
conversion from a Microstation drawing file
to an Arc Info coverage. The lineage of the
source data is unclear, but the
understanding is that a LADWF dataset
was obtained/modified by LDNR, the
USCOE obtained these data from LDNR,
and may have done further processing
including projection before providing the
source data to LOSCO. Published:

18 Elevation & Bathymetry Feature Classes Introduction Elevation and bathymetric data provide information about elevation of land surfaces (i.e. terrain), and water depths, respectively. Elevation refers to a spatially referenced vertical position above or below a datum surface. For land surfaces, the framework employs an elevation matrix. Elevation values are collected according to regularly defined post‐spacing. In areas of low relief, a finer measurement intervals are sought according to the data collection/application requirements. For water depths, the framework consists of soundings and a gridded water bottom model. Water depth is determined relative to a specific vertical reference surface, usually derived from tidal observations. Elevation data are used in many different applications. Elevation data is typically represented as contour maps, spot elevations, or a three‐dimensional perspective view. Elevation data are also used to build models and perform applications, ranging from line‐of‐sight calculations, to road planning, to water runoff. Elevation data are often combined with other data themes in applications and mapping. Maintained Data Layers The following Elevation & Bathymetry data layers are maintained by LAGIC.

23 Environmental Feature Classes Introduction Environmental feature classes includes information associated with environmental resources and conservation, especially how they relate to public health and environmental protection. Typical data layers include environment, pollution, waste storage, waste treatment, environmental impact assessment, remediation, nature, sensitivity surveys, monitoring, risk, nature reserves, landscape, natural resources, risk, heritage, water quality, and habitat. A descriptive ecosystem framework is an essential element for the successfully study of environmental systems across state, provincial, and country jurisdiction boundaries. Examples of how environmental data include jurisdictional or administrative boundaries, environmental resource management, risk assessment, ecosystems analysis and impact studies.

Pit Study Description: The 'Pit Study' was meant to identify the
remnants of former oil extraction sites
which pose the threat of creating an oil
spill. These remnants include many other
items besides the pits suggested by the
study title. e.g. tank batteries, collection
and separation apparatus, metering
stations and wells. In these coastal water
areas, erosion frequently exposes oil
production elements that were formerly
buried or on land, such as pipelines and
manifold headers. Additionally, the cribbing
surrounding a well may decay or fall away,
leaving the well exposed. These exposed
elements are susceptible to damage by
boat traffic as well as a hazard to
navigation. Pits of most concern are
generally associated with production
facilities and tank batteries where oil from
multiple wells is collected. These pits were
used for trash and as an emergency
overflow for oil. Pits associated with wells
themselves (Non-hazardous Oilfield Waste
or NOW pits) generally only contained
drilling fluids, rarely oil. These data are
held in a point dataset
[pit_study_LOSCO_1998] representing all
completed phases of the project - phases
1-7. The point dataset may be linked to

remedial action. The data set includes an
ArcView project file to display the data and
make all these appropriate linkages. The
subjects of the pit study were identified
through a variety of sources including
NASA Aerial Photography, Landsat
imagery, and oil well drilling/extraction
permit data. It is important to note that
the permitting process was not
implemented until the mid 1940's, whereas
the oil exploration/production in Louisiana
commenced about 1906. This means there
are many wells present which were never
documented in a permit. Furthermore,
poor location reference points in swampy
areas, coupled with some operator
independence, means that even permitted
wells may have been located 200-300 feet
from their permitted location. The
contractors for LOSCO used this
information as a guide for areas to
investigate for potential oil spill sources. In
the field, they noted all apparatus and pits
with this potential, even if they were not
looking for them in particular. The
positions of these features were
determined with GPS. The data associated
with each point includes feature type,
observations on the feature, and in some
cases, photographs and/or site plans.

34 Geodetic Control Feature Classes Introduction Geodetic Control feature classes provide a common reference system for establishing the coordinate positions of all geographic data. It provides the means for tying all geographic features to common, nationally used horizontal and vertical coordinate systems. The main features of geodetic control information are geodetic control stations. These monument points (or in some cases continuously operating reference stations ‐ active Global Positioning System control stations) have precisely measured horizontal or vertical locations and are used as a basis for determining the positions of other points. The geodetic control component of the framework data initiative consists of geodetic control stations, monuments, and related information ‐‐ the name, feature identification code, latitude and longitude, orthometric height, and ellipsoid height, and metadata for each station. The metadata for each geodetic control point contains descriptive data, positional accuracy, condition, and other pertinent characteristics for that point. Geodetic control information is crucial for the development of all framework and application‐specific data because it provides the spatial reference source to register all other spatial data. Furthermore, geodetic control can be used to plan surveys, assess data quality, plan data collection and conversion, and fit new areas of data into existing feature classes. Maintained Data Layers The following Geodetic Control data layers are maintained by LAGIC. National Geodetic Control Stations Description: This data contains a set of geodetic control
stations maintained by the National
Geodetic Survey. Each geodetic control
station in this dataset has either a precise
Latitude/Longitude used for horizontal
control or a precise Orthometric Height
used for vertical control, or both. The
National Geodetic Survey (NGS) serves as
the Nation's depository for geodetic data.
The NGS distributes geodetic data
worldwide to a variety of users. These
geodetic data include the final results of
geodetic surveys, software programs to
format, compute, verify, and adjust
original survey observations or to convert
values from one geodetic datum to
another, and publications that describe
how to obtain and use Geodetic Data
products and services. 2004

36 Geophysical Feature Classes Introduction Geophysical feature classes includes all geologic mapping information and related geo‐scientific spatial data (including associated geophysical, geochemical, geo‐chronologic, and paleontological data) that can contribute to the a better understanding of dynamic processes and phenomena of the Earth. Applications of geophysical data layers include offshore mineral resources (including oil, gas, sulfur, gold, sand and gravel, and manganese), soil data (consisting of georeferenced digital map data and associated tabular attribute data), meteorological (including model‐generated and observed surface, near surface, and atmospheric conditions), ocean currents, land‐water interfaces (e.g. shorelines and high‐tide markers), and more. In most cases, these data cover a wide range of scales. Maintained Data Layers The following Geophysical data layers are maintained by LAGIC. Astronomical High Tide Line Description: The astronomical high tide line was
compiled from National Wetlands Inventory
(NWI) 1:24,000-scale habitat maps that
were photo-interpreted from color-infrared
aerial photography acquired between
November 1988 and March 1989 at a scale
of 1:65,000. Inland extent of tidal
influence was then determined from the
1988 Chabreck and Linscombe marsh
vegetation maps, photo-interpretation,
field review, and information gathered
from discussions with regional and local
experts. Only semi-diurnal and diurnal
gravity tides are considered in the NWI
classification because of the general lack of
information on wind-influenced tidal
fluctuations and ranges. All saltwater
wetlands (saline, brackish, and
intermediate) in coastal Louisiana were
considered to be tidal unless impounded,
and tidally influenced freshwater wetlands
were included in the tidal zone as well. In
general, the division between salt water
and fresh water is considered to be the
limit of gravitation tidal influence for
coastal Louisiana. Arcs that close delineate
isolated areas above the astronomical high
tide line, but are not built into topological
polygons.

Louisiana State Soil Geographic Description: This data set contains vector line map
information. The vector data contain
selected base categories of geographic
features, and characteristics of these
features, in digital form. The information
was collected by clipping the existing
STATSGO soils map to the State of
Louisiana boundary. The data set used the
existing STATSGO soil maps as a data
development resource. The classified data
was derived from actual field identification
and sampling performed by the United
States Department of Agriculture and the
Soil Conservation Service. Review the
metadata file for more information.
Coverage is of the entire State of
Louisiana. The original STATSGO map is a
digital general soil association map
developed by the National Cooperative
Survey. It consists of a broad based
inventory of soils and nonsoil areas that
occur in a repeatable pattern on the
landscape and that can be cartographically
shown at the scale mapped. The soil maps
for STATSGO are compiled by generalizing
more detailed soil survey maps. Map unit
composition for a STATSGO map is
determined by transecting or sampling
areas on the more detailed maps and
expanding the data statistically to
characterize the whole map unit. The data
set consists of georeferenced digital map
data and computerized attribute data. The

topographic quadrangle units and merged
and distributed as statewide coverages.
The soil map units are linked to attributes

soils and their properties. 1998

•
•
•
•
•
•
the nation, states, protectorates, and statistically equivalent areas counties and statistically equivalent areas, incorporated places and consolidated cities, functioning and legal minor civil divisions, government owned or maintained property and/or leases federal‐ or state‐recognized American Indian reservations and trust lands, and Alaska Native regional corporations. Each of these features include the attributes depicting the name and the applicable Federal Information Processing Standard (FIPS) code. Features boundaries may include information about other features (such as roads, railroads, or streams) with which the boundaries are associated and a description of the association (such as coincidence, offset, or corridor). Governmental unit boundaries are used for a wide variety of applications. Some applications utilize boundaries for information and orientation; while others require the polygons to determine inclusion related to a number of other features. Business GIS is a very active field that uses these boundaries for statistical analysis and decision making.

Louisiana Coastal Wetlands Conservation Plan Boundary Description: This is a polygon dataset depicting the
areas of coastal wetlands in the state of
Louisiana. This area encloses the tidally
influenced coastal region three feet or
lower in elevation. This dataset was
developed as part of the Louisiana Coastal
Wetlands Conservation Plan funded by
EPA. The data set was created by
interpolation between 5 foot contour lines
on 1:24,000 USGS topographic maps, and
by interpretation of aerial photos and NWI
Habitat Maps. The resultant was drawn on
1:24,000 scale maps, then digitized to
create the dataset.

Louisiana Coastal Zone Boundary Description: This is a polygon dataset representing the
extent of the LDNR regulatory area defined
as the Louisiana Coastal Zone. This area
comprises a band across the southern
border of the state and ranges in width
from approximately 30 miles at the west
edge of the state to over 150 miles at the
eastern and Mississippi River Delta areas of
the state. A project to digitize the Coastal
Zone boundary from the 7.5' quad maps
was undertaken in June of 1997. This
project was not only the creation of a
digital line marking the boundary from
digital maps, but also a thorough research
project into where the line is actually
located based upon records from legislative
acts, the Louisiana Coastal Resources
Program Final Environmental Impact
Statement, and other information gathered
from the files of the Coastal Management
Division, the State Land Office and maps
from the Office of Minerals Resources. This
dataset is a product of that project. The
data set Point of Contact has a file with
copies of literature and references cited in
this report.

81 Hydrography Feature Classes Introduction Hydrography feature classes include surface water features such as lakes and ponds, streams and rivers, bayous, canals, oceans, and shorelines. Each of these features has the attributes of a name and feature identification code. Centerlines and polygons represent the geographic positions of these features. For feature identification code, many federal and state agencies use the Reach scheme developed by the U.S. Environmental Protection Agency (US EPA). Many hydrography data users require comprehensive attribution about the connectivity of the hydrography network and the direction in which the water flows. To meet these needs, additional elements representing the flow of water and connections between features may be included with the feature data. Shoreline data is often represented as hydrographic and geophysical data. In the hydrographic framework context, a shoreline represents the intersection of the water's surface with land. Shorelines are usually referenced to some analytically determined stage of the tide for coastal water, or other water level for lakes and rivers. Several shorelines, referenced to different stages of the water such as "mean high water" and "mean low water," are included in this context. These shorelines are included because different users require different shorelines and the complex, nonlinear relationships between various shorelines make it difficult to determine them analytically. Attributes can include the description of the tidal reference for the shoreline. Hydrography is important to many applications. As with other data themes, many users need hydrographic features as reference or base map data. Other applications, particularly environmentally oriented analyses, need the information for analysis and modeling of water supply, pollution, flood hazard, wildlife, development, and land suitability. Maintained Data Layers The following Hydrography data layers are maintained by LAGIC. Basin Subsegments from LDEQ source data Description: This is a polygon data set of watershed

TIGER/Line 2006 Second Edition, Hydrography of Louisiana Description: The 2006 Second Edition TIGER/Line files
are an extract of selected geographic and
cartographic information from the Census
TIGER database. The geographic coverage
for a single TIGER/Line file is a county or
statistical equivalent entity, with the
coverage area based on the latest available
governmental unit boundaries. The Census
TIGER database represents a seamless
national file with no overlaps or gaps
between parts. However, each countybased TIGER/Line file is designed to stand
alone as an independent data set or the
files can be combined to cover the whole
Nation. The 2006 Second Edition
TIGER/Line files consist of line segments
representing physical features and
governmental and statistical boundaries.
The files contain information distributed
over a series of record types for the spatial
objects of a county. There are 19 record
84 types, including the basic data record, the
shape coordinate points, and geographic
codes that can be used with appropriate
software to prepare maps. Other
geographic information contained in the
files includes attributes such as feature
identifiers/census feature class codes
(CFCC) used to differentiate feature types,
address ranges and ZIP Codes, codes for
legal and statistical entities,
latitude/longitude coordinates of linear and
point features, landmark point features,
area landmarks, and area boundaries.

86 Imagery Feature Classes Introduction Imagery feature classes provide a positionally correct image of the earth. Image data can include georeferenced planer and orthorectified raster data products. Planar imagery referrers to a georeferenced image prepared from aerial or satellite image or other remotely sensed data. Planer imagery does not account for geometric distortions. An orthoimage is a georeferenced image prepared from an aerial photograph or other remotely sensed data. Unlike planer imagery, orthorectified images account for measureable displacements of the imagery caused by sensor orientation and terrain relief have been removed. An orthoimage has the same geometric properties as a map and has a uniform scale. Digital images are composed of an array of georeferenced pixels that encode ground reflectance as a discrete digital value. Many geographic features, including those that are part of the framework, can be interpreted and compiled from an orthoimage. Orthoimages can also serve as a backdrop to reference the results of an application to the landscape. The framework may include imagery that varies in resolution from sub‐meter to tens of meters. Accurately positioned, high‐resolution data (pixels of 1 meter or finer) are presumed to be the most useful for supporting the compilation of framework features, particularly those that support local data needs. In some areas, lower‐resolution imagery may be sufficient to support the framework and applications. Orthoimagery provides a useful tool for a variety of applications. Because many land features can be seen on an orthoimage, it can serve as a backdrop for visual reference purposes, saving the expense of creating vector files of features that are needed only for reference. Orthoimagery can be used to compile vector themes photogrammetrically. Maintained Data Layers The following Imagery data layers are maintained by LAGIC. Land Cover Classification for the Louisiana GAP Analysis Description: This data set consists of digital data
describing the land use/land cover (mainly
vegetation, but including water and urban
environments) for the State of Louisiana at

using Landsat 5 Thematic Mapper satellite
imagery, botanical surveys, color infrared
aerial photography, and existing coastal
Louisiana habitat maps produced by the
U.S. Fish and Wildlife Service's National
Wetlands Inventory. Attribute fields
describe the different land cover types
occurring within the polygon or associated

For a detailed definition and discussion on
MRLC and the NLCD 2001 products, refer
to Homer et al. (2004) and
http://www.mrlc.gov/mrlc2k.asp. The
NLCD 2001 is created by partitioning the
U.S. into mapping zones. A total of 66
mapping zones were delineated within the
conterminous U.S. based on ecoregion and
geographical characteristics, edge
matching features and the size
requirement of Landsat mosaics. Mapping
zone 37A encompasses whole or portions
of several states, including the states of
Texas, Arkansas, and Louisiana. Questions

97 Land Use Cover Feature Classes Introduction Land Use Cover feature classes include flood zones, Land Use refers to the human activities that are directly related to the land. Land Cover describes the vegetation, water, natural surface, and manmade features of the land. The interpretations are based on a land use and land cover system developed for use with remotely sensed data. Land use is traditionally organized into hierarchical classifications consisting of two defined levels. Land use and land cover areas are classified into nine major categories: urban or built‐up land, agricultural, rangeland, forest, water areas, wetland, barren land, tundra, and perennial snow or ice. Each general class is subdivided into several detailed classes. Maintained Data Layers The following Land Use Cover data layers are maintained by LAGIC.

MRLC Consortium is a partnership of
federal agencies (www.mrlc.gov),
consisting of the U.S. Geological Survey
(USGS), the National Oceanic and
Atmospheric Administration (NOAA), the
U.S. Environmental Protection Agency
(EPA), the U.S. Department of Agriculture
(USDA), the U.S. Forest Service (USFS),
the National Park Service (NPS), the U.S.

of the project is to generate a current,
consistent, seamless, and accurate
National Land cover Database (NLCD) circa
2001 for the United States at medium
spatial resolution. This landcover map and
all documents pertaining to it are
considered "provisional" until a formal

For a detailed definition and discussion on
MRLC and the NLCD 2001 products, refer
to Homer et al. (2004) and
http://www.mrlc.gov/mrlc2k.asp. The
NLCD 2001 is created by partitioning the
U.S. into mapping zones. A total of 66
mapping zones were delineated within the
conterminous U.S. based on ecoregion and
geographical characteristics, edge
matching features and the size

1:24,000 Papermap Quadrangle Index of Louisiana Description: This is a polygon dataset delineating the
geographic footprint of the 24k (7.5')
series map sheets published by the USGS.
Because most of these map sheets have
also been scanned into DRGs, this index
also represents the area of valid data on
24K DRGs for the area. Because the
neatline of paper quad maps was formed
by a regular grid in geographic
coordinates, NAD27, this dataset was
generated from a regular grid defined in
that coordinate system. In subsequent
processing this grid was projected to
geographic coordinates, NAD83. The
projection was done to make this dataset
compatible with other vector data in the
same coordinate system. As a result, the
area enclosed by each polygon in this
index represents the same geographic area
depicted on the corresponding paper map,
but the latitude / longitude value for each
polygon side and and corner in geographic
coordinates, NAD83 are not exact multiples
of full and half degrees. The grid is not
totally regular. In the Chandeleur Islands
area, the normal footprint of USGS maps
were shifted a few minutes east and west
to cover the area with the fewest map
sheets.

•
roads ‐‐ centerlines, feature identification code (using linear referencing systems where available), functional class, name (including route numbers), and street address ranges; emergency evacuation routes ‐‐ government designated roads and/or routes that facilitate emergency evacuations; trails ‐‐ centerlines, feature identification code (using linear referencing systems where available), name, and type; railroads ‐‐ centerlines, feature identification code (using linear referencing systems where available), and type; navigable waterways ‐‐ centerlines, feature identification code (using linear referencing systems where available), and name; airports and ports ‐‐ feature identification code and name; bridges and tunnels ‐‐ feature identification code and name; and intermodal transportation ‐‐ include the above features, as well as transportation of goods and services (e.g. pipelines, data networks, and electrical power). Transportation information is used in many applications. Some use it only for reference purposes, as an element of base mapping, while many others use it to attach other types of information, such as address‐related information or street characteristics. Transportation features and related data are important elements of many planning applications. Geocoding applications use road and related address data for uses ranging from marketing analysis to site identification. Routing applications use street network data for operations such as vehicle dispatch and fleet management. Maintained Data Layers The following Transportation data layers are maintained by LAGIC.

State Maintained Highways in Louisiana Description: This dataset represents the state
maintained road network of Louisiana. The
dataset includes Interstates, US highways,
and Louisiana State Highways. This dataset
was compiled by Louisiana DOTD source
data. The dataset includes selected data
from the DOTD Surface Type Log file. The
source dataset was derived from sources
including USGS quads, aerial photography,
highway plans, DOTD's control section road
network and existing general highway
maps. The source data set originated in
1983-1985 by digitizing 7.5' USGS quads
on high precision input tables, but is
updated regularly at LDOTD using the
other sources mentioned above. February 5, 2007

physical features and governmental and
statistical boundaries. The files contain
information distributed over a series of
record types for the spatial objects of a
county. There are 19 record types,
including the basic data record, the shape
coordinate points, and geographic codes
that can be used with appropriate software
to prepare maps. Other geographic
information contained in the files includes
attributes such as feature
identifiers/census feature class codes
(CFCC) used to differentiate feature types,
address ranges and ZIP Codes, codes for
legal and statistical entities, latitude
/longitude coordinates of linear and point
features, landmark point features, area
landmarks, and area boundaries. 2006

routes are described in the National
Hazardous Material Route Registry
(NMHRR). The on-line NMHRR linkage is

asp With the exception of 13 features that
were not identified with the Tiger/Lines,
Hazmat routes were created by extracting
the TIGER/Line segments that
corresponded to each individual route.
Hazmat routes in the NTAD, are organized
into 3 database files, hazmat.shp,
hmroutes.dbf, and hmstcnty.dbf. Each
record in each database represents a
unique Tiger/Line segment. These
Tiger/Line segments are grouped into
routes identified as character strings in the
ROUTE_ID field in the hmroutes.dbf table.
The route name appearing in the
ROUTE_ID is assigned by FMCSA and is
unique for each State [this sentence could
be deleted - it doesn't add a lot to it]. The
