topic Genaralize voting districts (precincts) in ArcGIS Spatial Analyst Questions https://community.esri.com/t5/arcgis-spatial-analyst-questions/genaralize-voting-districts-precincts/m-p/201729#M2827 <HTML><HEAD></HEAD><BODY><P>The precincts in my county change every year. I want to classify voting patterns over 8 years. It would be helpful if there was a common shape I could use to compare the precincts over several years. Voting districts (precincts) are comprised at a smaller scale of Census blocks and consistently roll up into legislative districts. Census tracts or Census blocks don't align. Is there a GIS tool about which I should be learning? Suggestions would be appreciated and if there is a group on Geonet exploring voting I would appreciate collaboration.</P></BODY></HTML> Sat, 01 Jul 2017 11:12:32 GMT BrianHovis 2017-07-01T11:12:32Z Genaralize voting districts (precincts) https://community.esri.com/t5/arcgis-spatial-analyst-questions/genaralize-voting-districts-precincts/m-p/201729#M2827 <HTML><HEAD></HEAD><BODY><P>The precincts in my county change every year.
