Example Conversions
Converting WGS84 to UTM Zone 11 using cs2cs
- cs2cs -v +proj=latlong +datum=WGS84 +to +proj=utm +zone=11 +datum=WGS84
-bash-4.2$ cs2cs -v +proj=latlong +datum=WGS84 +to +proj=utm +zone=11 +datum=WGS84 # ---- From Coordinate System ---- #Lat/long (Geodetic alias) # # +proj=latlong +datum=WGS84 +ellps=WGS84 +towgs84=0,0,0 # ---- To Coordinate System ---- #Universal Transverse Mercator (UTM) # Cyl, Sph # zone= south # +proj=utm +zone=11 +datum=WGS84 +ellps=WGS84 +towgs84=0,0,0 -118.00 34.00 407650.40 3762606.66 0.00

Building Proj4
proj4 built on Centos using the ./configure make, make install. Since we are building on a shared cluster, we needed to ./configure --install:/user/scec-00/maechlin/workspace/proj4
