Building Area and Pin
Maps
Introduction
The tasks of this tutorial are in the area of cartography or map
making. You will build some sophisticated maps that crime analysts
and police officers will find valuable. First, you will build area (or
“choropleth”) maps. They use color shading of areas within
boundaries to provide information on an entire city. While we could
use any map boundaries (like census tracts or car beats), we will use
square grid cells because they are the easiest area maps to read. With
these maps, if you spot a hot grid cell of interest, you can drill down
(or zoom in) and points will appear for individual crimes, and then
to data records with victim, suspect and other variables. Second,
you will also build a sophisticated pin (or point) map for use by
uniformed officers. These maps have several crime types by shift
for the most recent four weeks. The crime points of the last few days
are highlighted with larger symbols to show current crime patterns
in the context of older but recent crimes.

Tutorial 3 : Building Area and Pin Maps
Build Thematic Maps
The next task is to color code grid cells according to how many burglaries occurred in
each cell. We need to define the ranges, assign colors to each range, and color-code the
grid cells appropriately.
Step 1: Specify the Type of Thematic Map
1.
2.
Click Map, Create Thematic Map....
Click the top left button, Ranges, scroll down in the Template
Name panel if necessary, click the template name Region Ranges
Default, and click Next>.
Step 2: Specify the Table and Field to be Displayed
1.
2.
Click on the drop-list arrows for each field and click:
· Burglary2000Series199804 as the table
· BurglaryCount199803 as the field
Click Next>.
Step 3: Define the Ranges
You will build custom ranges (that result in an exponential scale 0, 1, 2-4, 4-8, 9-16, and 16
and greater - powers of two) and colors, instead of using the defaults. An exponential
scale is good for “long-tailed distributions” and accomodates a large range of values with
more detail at the smaller values.
1.
2.
3.
4.
Click Ranges....
Click the drop-list arrow in the Method field and click Custom.
Click the drop-list arrow in the # of Ranges field, click 6, and
click Recalc.
In the large panel enter the minimum and maximum for each range,
using the >=Min and <Max fields.
0 to 1
1 to 2
2 to 5
5 to 9
9 to 17
17 to 1000 (the 1000 ensures that the last range will catch all the
extremely high cases.)
5.
Click Recalc, OK, and OK again when you are finished.
The result is a choropleth map showing hot burglary cells with red.

Step 4: Assign Colors and Patterns to each
Range
There are four ways to assign colors and patterns. You will look at or try three of
them out. The fourth, creating you own colors, is not often needed.
Option 1: Accept The Default Colors
1.
2.
Click on the map, then click Map, Modify Thematic Map....
Click Styles... to see what they are.
You will find a range of colors from red (highest) through pale red and pink to
gray (lowest). Notice at the top that “Autospread Color” is selected.
Option 2: Let Mapinfo Compute A Color Ramp
We’ll keep the red, but change the gray to white.
1.
2.
Click on the gray button next to the 0 to 1 range in the Customize Range Styles window
Click the drop-list arrow in the Foreground field and click the
white square in the upper left of the color palette that appears
and click OK, OK, and OK again.
Option 3: Pick Colors From Mapinfo’s Color Palette
Next is a custom color range. The table below gives the row-column position in the
color palette for each color.
1.
2.
3.
Click Map, Modify Thematic Map..., and Styles....
Click the Auto Spread None radio button at the top of the
Customize Range Styles window.
Click on the button for each range, click the drop-list arrow in the Foreground field, pick the color from the palette,
using the same steps as you used to pick white under Option 2
above, and click OK and OK again when done to see your
map.

Build a Change Map
To show changes from March to April, we will create a sophisticated, generalpurpose, two-color scale, running to dark red for increases and dark blue for decreases, with white in the middle range (-1 to +1). Because it is symmetric around
zero, the point of no change, it is easy to read and interpret. We will save this template for reuse with other crime types.

How to Get Crime Mapping
Started in Your Agency
You can start crime mapping strictly by running MapInfo interactively, as done in
this tutorial, and later automate tasks as you become more proficient. This is what
the Pittsburgh Bureau of Police and Rochester Violent Crime Task Force are doing
to produce daily crime maps for officers and detectives.

• Create circular buffers around crime-prone points (like bars) or other points
(e.g., schools) and regularly retrieve crime data occurring within those buffers.
• Digitize boundaries of special study areas and extract corresponding data (e.g.,
before, during, and after interventions).
• Produce statistics for study areas (counts, averages, etc.)
• Produce charts and tables to accompany maps.
Map Makers:
• Clip out jurisdiction maps from county maps (maps usually come by the county).
• Digitize or dissolve administrative boundary maps (precincts, car beats, foot
patrol areas, etc.) using heads-up digitizing.
• Understand and change map projections so that all map themes overlay each
other.
• Edit TIGER map street centerlines so that their graphics line up with moreaccurate curbs created by your local government agency.
• Build layouts for printing that have two or more maps and other documents.
• Edit and repair street centerline maps to increase address matching accuracy.
• Hot link data, images, or charts to map features for hyperlink, map access.

What Do You Need to Do to Start Building Your
Crime Mapping System?
Data Preparers:
• Write data extraction and exporting procedures, or provide a data layer to
access CAD, offense, and arrest records on a real-time or daily basis. You just
need flat files with street address, date, time, and crime code at minimum.
• Build an aggregate crime code table that combines codes on variations of crimes
to a single code for mapping and analysis. For example, Pittsburgh has several
robbery crime codes (by location type and weapon used) that we combine to
“robbery”. An example for Rochester, NY is in the
c:\CrimeMapTutorial\Documentation folder.
Map Makers:
• Purchase or obtain TIGER maps (street centerline, census tract and block
groups, political boundaries), census data, and yellow/white pages points from
vendors.
• If available, obtain land parcel, building footprints, curbs, and other layers from
your local government agency. These layers can be used when zoomed far in to
establish the land use and place context of crime, and to provide access to realproperty data (owners, etc.)
