Anyone experiencing similar issues. ------------- Ed We have experienced the frustration of block boundaries between the 2000 Census and the 2010 Census being dramatically different within our urbanized area. Our GIS experts have had a difficult time assembling and reconciling the differences in order for us to simply compare data on a block-by block basis. Do you know if this is unique to us or are we in the same boat as others? -- Ed Christopher FHWA Resource Center Planning Team 4749 Lincoln Mall Drive, Suite 600 Matteson, IL 60443 708-283-3534 (V) 708-574-8131 (C) _______________________________________________ ctpp-news mailing list ctpp-news(a)chrispy.net http://www.chrispy.net/mailman/listinfo/ctpp-news
