It's not NAD83 that's giving you troubles, but the particular projection the data is in. NAD83 is almost exactly the same as WGS84 (at least for this century). > http://www.ngs.noaa.gov/cgi-bin/spc_getgp.prl > > are giving me ridiculous answers. This page doesn't seem to accept both NAD83 and feet, so that's to be expected. > OGRFeature(schoolLocation):23 > SCHOOLTYPE (String) = HIGH > SCHOOLNAME (String) = RIO GRANDE > POINT (1507003.249 1473733.624) > > I know the correct answer for this item is approximately latitude > 35.052536, longitude -106.69394, but am not sure how to do this > translation for all items in the shapefile. How about the following? $ echo 1507003.249 1473733.624 | invproj -f %f +init=epsg:2258 -106.695765 35.049850 According to the data in OSM, it's on the other side of the road as the correct location. Is that accurate enough? >From what I see, you're already using OGR. Have you tried the following? It should convert the shapefile with state plane coordinates into a shapefile with WGS84 coordinates. $ ogr2ogr -t_srs EPSG:4326 shapefile_wgs84.shp shapefile.shp Gabriel. _______________________________________________ newbies mailing list [email protected] http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/newbies
