[MetaCRS] Anyone developing CSMap for NET?

Thu Jan 20 08:55:21 EST 2011

Hi Andre,

If I recall correctly - there was both namespace and versioning collision.
Map 3D expected binary compatible version of MGOS wrappers. I think it was
Map 3D 2011 and my set of MGOS 2.1 libraries. There was slight difference in
assembly versions build numbers. 

Regards,
Maksim Sestic

Hi Maksim,

Could it be that you had a name space collision, i.e. you basically built
your app against the MgOS wrappers but you've then been unable to load your
assembly into M3D because that had its own version of the SWIG wrappers?

If that was true - which version have you been using?

André

Hi Hugues,

The idea was to use MGOS managed wrappers to access CS-MAP functionality.
The API I've been coding was supposed to work on AutoCAD and its verticals,
but was basically host-neutral (had a "provider" for managed ObjectARX).
Everything worked fine, except on Map 3D. Somehow I had problems running my
set of MGOS libraries side-by-side with Map's wrappers for MGOS wrappers for
CS-MAP :-) I don't remember what was exact issue anymore, but I resorted to
GDAL's OGR managed wrapper + CS-MAP's NameMapper.csv file to resolve naming
issues when creating FDO datastores.

Regards,
Maksim Sestic

Hello Maksim,

And what kind of problem would that be?
Can you please be more specific?
Thanks

Hugues

Hi Norm,

There's actually a problem running latest version of open soruce managed
MapGuide API and AutoCAD Map 3D side-by-side (that is - in case of managed
code running within Map).

Maksim Sestic

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?

Steve

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