KMSTrans2 depends on GDAL/OGR
for transformation of data sources in the batch tab as well as for
displaying a coast line in the map window. Currently only the OGR
part of GDAL is used to transform vector data.
A prepackaged version of KMSTrans2 with prebuilt binaries will come also with a (minimal) GDAL installation, which the binaries are linked against (gdalxxx.dll located in the bin subfolder, where xxx is a version number e.g. gdal110.dll)
If you have a compatible gdal installation (currently gdal110.dll) on your computer, possibly with more drivers enabled, you can override the default GDAL installation simply by deleting or renaming gdalxxx.dll in the bin sub folder. You may also want to delete or rename the gdal-data sub folder - if this folder is present KMSTrans2 will set the GDAL_DATA environment variable to point to there.
Advanced users are encouraged to install a full gdal version,
available e.g. from here,
in order to enable all OGR drivers (like WFS, Postgis and
Spatialite).
If you build the binaries yourself with the included build script
- build.py - it is up to you to
choose an appropriate GDAL installation/version to link against.
