I am working with some GeoTiff files that given images projected in the
Lambert Conic Conformal projection. This projection is not currently supported
by GeoTools and when I attempt to read the file the GeoTiffReader class
throws an exception with the comment
"ProjCoordTransGeoKey(8) is not currently supported"
This is a known bug (GEOT-671). I would like to implement the
projection and perhaps contribute code to the project.
My problem in doing so is that I have been finding it very difficult to find my
way around the GeoTools code. The mathemetics is easy enough, but
the software issues are sometimes confusing and the documentation
rather sketchy (and here I refer not just to the advanced issues like
teasing the algorithms out of existing code, but even simply things
like the relationships between classes and flow-of-control when
putting together an implementation).
Could somebody provide guidance on the general procedure for
adding a new projection in this case? Also, while I'm at it I might
be able to contribute code for other missing projections are there
other important projections that are needed? There are
limits to what I can do, of course, but if there were one or two other
very important projections I might be willing to take a crack at it
just as a way of giving something back to the community.
