GDAL

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.
For all operating systems, except Windows, KMSTrans2 will use a 'system install' of GDAL, i.e. the GDAL libraries and dependencies must be installed in locations pointed to by relevant environment variables.

Windows only:

A prepackaged version of KMSTrans2 with prebuilt binaries  will come also with a (minimal) GDAL installation, which the binaries are linked against (currently gdal110.dll). The directory layout of the default GDAL installation is (relative to the root directory of KMSTrans2):

gdal ->
        bin             (subfolder containing gdal binaries, e.g. gdalxxx.dll and other dependencies)
        gdal-data  (subfolder containing gdal data files)
        plugins      (subfolder containing optional gdal plugins)

There are several ways of customizing the used gdal installation:

The GDAL installation can also be customized from the 'GDAL settings' dialog, which is opened from the 'Settings' menu:
Or:

Changes to the GDAL setup requires a restart to take effect.
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).

Building binaries yourself:

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.
