[MetaCRS] Slimming down the CS-Map distribution

[Norm Olsen]

Hello Jackie . . .

You can remove any and all but one definition from the dictionary and all should work fine.  There needs to be at least one (maybe two) for things to work right.

The definitions are maintained in the coordsys.asc file.  The supplied compiler compiles the coordsys.asc file to produce a coordsys.csd file which is the actual binary dictionary referenced by the run time.  You can do the same thing with the datums.asc and ellipsoid.asc files, but these are much smaller and you run the risk of deleting something that is referenced elsewhere (i.e. in coordsys.asc).

Subject: [MetaCRS] Slimming down the CS-Map distribution

Hi All,

Is there a safe way to cut down the size of the coordinate system dictionaries that come with CS-Map by removing coordinate systems I don't need or will never use?

I'm primarily using the MgCoordinateSystem wrapper for CS-Map, and I want to know if I can remove coordinate systems in a way that will not affect this wrapper's ability to enumerate and fetch coordinate system definitions.

- Jackie
