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

FAQ

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
  • Installation of proj4 on Mac (high sierra) failed.
  • Installation of current proj4 on USC HPC succeeded.
  • Didn't try installing pyproj on Mac. It can use either installed proj4, or try to build its own
  • Used conda install pyproj on Anaconda 2 instance on USC HPC
