I was trying to point out that, regardless if the units are meters or feet, when you transform to a different CRS, you change all three values of the location, x,y and z. For example:
micha@TP480:~$ echo "35.3 30.8 -180" | cs2cs +init=epsg:4326 +to +init=epsg:2039 228595.08 523262.05 -200.28
In the EPSG 2039 CRS my elevation has "dropped" by 20 meters (!) compared to WGS84
Micha, Global warming? :-) With my data set the original and converted data for one station have the same elevation (in meters): Rhododendron 3.8 NW,45.3596,-121.9742,399.9 Rhododendron 3.8 NW,2384511.31243653,189175.421986476,399.9 Best regards, Rich _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/grass-user
