I have satellite imagery for north AL somewhere. It's a tad bulky. One of the problems with scans of USGS quads is that TVA is the "mapping authority" for the Tennessee River Valley, so USGS didn't have the data. I haven't looked in a few years, so I don't know if that is still the case, or if there is a source besides USGS (TVA did not provide them). I do have some USGS contour lines, can;t remember where I got them. I displayed them with GDAL and played a bit with conversion to shapefile. IIRC I did not have complete coverage, and ahpefile conversion was problematic (different dbfawk signatures at the very least, and maybe some other differences between individual files as well.) I (we?) will eventually have to figure out a good way to take advantage of the OSM stuff - shapefile conversion, portable tiles server, or whatever - since that's the direction all of the available data seems to be headed. -Jason kg4wsv _______________________________________________ Xastir mailing list [email protected] http://xastir.org/mailman/listinfo/xastir
