[comp.unix.xenix.sco] Any Redistricting software available?

dwyer@nssdc.gsfc.nasa.gov (Al Dwyer) (09/21/90)

Early in 1991 all 50 states and thousands of counties and 
municipalities will be receiving data from the 1990 census. Many will 
be using this data for redistricting the congressional, state, county, 
and even local ward boundaries that currently exist.
Does anyone know of any software that exists to facilitate this 
process? I'm particularly after such software to run on an Altos 
system using Xenix, but also would like to hear of any running under 
MS/DOS.
