I am currently using PyProj for a project, and would like to transform from WGS-84 (or other systems) to the China-specific datums for writing into kml files. I have seen other packages specifically for fixing the China projection problem, but would rather use PyProj if possible.
Are there an EPSG codes for the BD-09 or GCJ-02 datums? I was unable to find any. Alternately, is there any other way to transform WGS-84 to GCJ-02 or BD-09 using PyProj?
