To Sweson Yang and other TransCAD Users:
In response to your message, Version 3.5 of TransCAD contains all the
software routines required to update your TAZs and create the equivalency
files containing the CENID and POLYID required by the Census Bureau. The
software checks for and displays non-allowable boundary segments and
provides full redistricting capabilities including instant update of summary
fields and the disolving of polygons to create the new TAZ layer. These
features are similar to those found in our redistricting software, Maptitude
for Redistricting. For a more complete description, click the redistricting
link on our Web site, www.caliper.com
. We are sending you the new version.
If other TransCAD users would like to use TransCAD for this purpose and you
do not yet have Version 3.5 with the TAZ update features, please let me
