[Gdal-dev] Re: your GDAL in C#

[Tamas Szekeres]

Hi,

The attachment you have referred is a separate project and I don't
know whether it was developed further or not. Maybe Simon Perkins
knows more about it.

However you can also use the GDAL C# SWIG interface contained by the
gdal project
and can be accessed from the CVS.
For more details about the CVS access see:
http://www.gdal.org/download.html

Best Regards,

Tamas Szekeres
