Let's not forget the fact that "cartographic data" (ie. street data) was never a goal of the Census. It simply fell out of the LineFile format due to their need to track data at the block and tract levels. It was literally an afterthought. Of course, since then, geographers have been using it to extract roads and other features and have increasingly put pressure on the Census to make this a real part of the Census and not a byproduct. As a result, the Census began releasing periodic updates every few years with cartographic updates. It wasn't great, but it was better than nothing. They are finally getting serious about it and storing the geographic referenced data is well known formats. Hopefully, they'll start working on the accuracy of that data... -- 73, de Brad KB8UYR/6 <rez touchofmadness com> _______________________________________________ Xastir mailing list [email protected] http://lists.xastir.org/cgi-bin/mailman/listinfo/xastir
