Building Mapping
An up-to-date building inventory database is crucial for a wide range of uses, from urban planning to real estate
management. Woolpert can automatically and interactively extract building footprints from lidar and aerial
photography. Woolpert’s technique can deliver an accurate building layer or update existing datasets using the
existing source data.
Terrain Modeling
Woolpert has a well demonstrated effective and rapid methods for producing accurate terrain models
that can be utilized in urban planning, storm water modeling, flood analysis as well as siting analysis.
Impervious Surfaces Mapping
To provide a cost effective and accurate impervious surfaces mapping solution, Woolpert has developed semiautomated feature extraction techniques that takes advantage of the ubiquity of digital imagery and lidar to
perform object recognition, scene recognition and delineation. Woolpert’s impervious surfaces mapping
solution is relatively fast and produces reliable results that can be for storm water billing or environmental
analysis.
Land Use / Land Cover Mapping
Woolpert has developed finely tuned and robust mapping algorithms to delineate and map various land cover
categories from imagery and lidar in order to create up-to-date and accurate land cover and land use maps.
Because our approach is rules-based, it is repeatable and consistent and robust enough to withstand the
pressures of changing requirements arising from any complex geographic landscape.
Hydrology
Woolpert offers a unique approach to updating hydrology. Woolpert understands that elevation and
hydrography are intrinsically linked, one forms the other. From mapping streams, rivers and lakes to delineating
watersheds and drainage basins, Woolpert offers a comprehensive solution to your hydrological needs.
Forest Mapping
Foresters and others with an interest forest management and other operational activities require accurate data
to plan their activities. Woolpert can assist in mapping forest areas, assessing forest health, calculating forest
biomass, classify terrain, identify drainage patterns and deriving other forest related metrics such as stem
density and canopy height models.
Change Detection
Woolpert offers a change detection solution that at its core seeks to provide up-to-date and accurate
information about the changes in the landscape where multi-temporal data sets are available. The types of
changes that can be quantified and mapped through this solution can range from short-term phenomena such
as flooding to long-term phenomena such as urban growth.
