[CIG-SHORT] question about coordinate transform

[tu xiang]

Hello, everyone

Does the geographical coordinates (+lat_0=45.5231 +lon_0=-122.6765 +k=0.9996) correspond to the origin of Cartesian coordinates for mesh in the 3D subduction example?

I want to try to transform some geographical coordinates, then, I write next code:
#!/usr/bin/env nemesis

import coordsys
import numpy as np
point=np.array([[45.5231,-122.6765,0.9996],[46.0,-122.0,1.0],[45.0,-122.0,0.5]])
print point
print type(point)
coordsys.geoToMesh(point)


But it output errors!

Traceback (most recent call last):
  File "demo.py", line 9, in <module>
    coordsys.geoToMesh(point)
  File "/home/bxu/covert/coordsys.py", line 54, in geoToMesh
    convert(xyz, cs_mesh(), cs_geo3D())
  File "/home/bxu/pylith/pylith-2.2.1rc1-linux-x86_64/lib/python2.7/site-packages/spatialdata/geocoords/Converter.py", line 33, in convert
    geocoords.Converter.convert(coords, csDest, csSrc)
RuntimeError: Error while projecting location.
  latitude or longitude exceeded limits
  projection: tmerc
  units: m
  proj options: +lat_0=45.5231 +lon_0=-122.6765 +k=0.9996
  lon: 0.794528
  lat: -2.14111

It said the latitude or longitude exceeded limits, I do not know what does it mean?

Looking forward to your reply.
Best regards,
Tu Xiang
