No. Nevada East Zone State Plane Coordinate System is not the same as UTM, Zone 11 (even though it may lie in UTM zone 11).
Thanks, Tom. It's been long enough since I last needed to do this type of conversion that I forgot to use the EPSG numer.
What you want is to tell cs2cs to use the EPSG number 3421 as the target coordinate system. From the PROJ.4 epsg file, that means: # NAD83 / Nevada East (ft US) <3421> +proj=tmerc +lat_0=34.75 +lon_0=-115.5833333333333 +k=0.9999 +x_0=200000.00001016 +y_0=8000000.000010163 +ellps=GRS80 +datum=NAD83 +units=us-ft +no_defs <> which you can see matches your PROJ_INFO information.
(On my system, the EPSG database for PROJ.4 is in /usr/local/share/proj/epsg)
On my Slackware systems it's /usr/share/proj/epsg.
You should use this command line instead: cs2cs +proj=latlong +datum=NAD83 +to +init=epsg:3421
Good. I don't need to separately specify each parameter, then. Glad I asked for the reality check. :-) Much appreciated, Rich _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
