Maptitude for Redistricting
is a specialised version of Maptitude
that is widely used by all levels of government in the
United States for a process called
redistricting. This is more familiar to UK government users as boundary
revisions and, since the UK is said to have more administrative boundary
changes per year than the rest of the European Union put together,
Maptitude for Redistricting is a critical tool to assist in this
process.
Maptitude for
Redistricting is competitively priced and includes all the tools needed
to build and analyse boundary revisions. The software has a custom menu
system and toolbox that enables users to create a new plan from a map, a
template, or an existing plan. It also allows
users to display that plan as district boundaries or a thematic map,
import plans from other GIS formats, and
export data to an equivalency file in dBASE and other industry-standard
formats.
Maptitude for
Redistricting also has some very powerful geographic editing tools for
creating boundaries from scratch. In addition to allowing manual editing
of boundary lines, with Maptitude for Redistricting a user can actually
select the underlying features that define the boundaries and use them
to build the new polygon, thus ensuring a perfect alignment.
For example, lets say a
ward is bounded by three streets and a river. You would select these
four segments, click OK, and you would have your new ward, perfectly
aligned with the underlying geography. If part of the boundary goes
through a field, you can add that line as an invisible boundary, which
then allows you to select that line as part of the polygon boundary.
By having all of the
underlying line segments that define the boundaries, Maptitude can
create a metes and bounds report that provides the legal description.
Here's an example of a report created automatically by Maptitude:
District 0010. All of
that portion of Johnson County bounded and described as follows: 1.
Beginning at the point of intersection of S. Lackman Road and W. 191st
Street, and proceeding northerly along S. Lackman Road to W. 167th
Street, and proceeding easterly along W. 167th Street to Nonvisible
boundary, and proceeding easterly along Nonvisible boundary to the
Overland Park city line, and proceeding easterly along the Overland
Park city line to Nonvisible boundary, and proceeding easterly along
Nonvisible boundary to Unnamed Local road, and proceeding easterly
along Unnamed Local road to W. 167th Street, and proceeding easterly
along W. 167th Street to the Overland Park city line, and proceeding
easterly along the Overland Park city line to W. 167th Street, and
proceeding easterly along W. 167th Street to Metcalf Avenue, and
proceeding southerly along Metcalf Avenue to W. 191st Street, and
proceeding westerly along W. 191st Street to the point of beginning.
2. Except for all of the region bounded by the Overland Park city
line. 3. Except for all of the region bounded by the Overland Park
city line.
Users can also:
- compute measures of
compactness and check for completeness and contiguity
- zoom to unassigned
polygons or discontiguous portions of a district to verify the
integrity of a plan.
Privileged access to data
in the UK academic and public sectors would make the use of Maptitude
for Redistricting especially valuable to researchers and the Boundary
and Local Government Commissions.
