[MetaCRS] Anyone developing CSMap for NET?

[Norm Olsen]

Hello Steve . . .

Categories was an Autodesk addition to the CS-MAP package, thus it is handled quite differently and much of the functionality is actually implemented in the MapGuide API.  As far as figuring out what is available as far as API, I suggest you look at the CoordSysCategoryDictionary.cpp module.

There is a list for MetaCRS which is quite small and more suitable for questions regarding CS-MAP.  I'm not sure exactly how to get on that list, but it should be pretty easy.  (MetaCRS is an open source group for coordinate system related stuff in general.  It includes CS-MAP, Proj4, Proj4 emulations in Java, and other CRS related stuff.)

Thanks André, I had a look at the MapGuide classes, but decided there's just too much baggage - it would take me a month to get up to speed, and make any installation a bit unwieldy.

So I'm looking once more at using CSMap itself. Having actually looked at the user manual, I now see how to iterate over coordinate systems, datums, and ellipsoids. I was hoping that access to information on categories would follow the same pattern, but it looks like they're handled differently. Is there any documentation out there, or example code that shows how categories might be used as part of a coordinate system browser?

P.S. Is there a CSMap developers list that I should perhaps be posting to?
