Proj4

Coordinate system conversions are needed for several SCEC projects.

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
