I tried reinstalling proj: sudo apt-get --reinstall install proj Do I need to do anything else to get the grid shift files? Where should they be installed? In the readme files, they give a cs2cs example, but I don't get the correct results. Here's my version: cs2cs +proj=latlong +datum=NAD27 +to +proj=latlong +datum=NAD83 -117 30 117dW 30dN 0.000 Should be: 117d0'2.901"W 30d0'0.407"N 0.00 Clearly I don't have the grid shift files, but I'm not sure where I'm supposed to get them or where they're supposed to be.
