Dear all,
I'm pretty sure it has been asked before, however I wasn't able to find
an answer to my question in the archive, so please bear with me...
I'm using a number of oss geo tools under Windows using the OSGeo4W
binary distribution. I have installed the 1.6-version of GDAL and can
find it under c:\osgeo4w\apps\gdal-16. This directory also includes the
Python bindings that I want to use instead of my current ones. Now I'm
stuck on how to achieve this. The usual *from osgeo import gdal* always
supplies me with the current 1.5-version of the bindings, so I somehow
suspect that I have to tell Python to prefer the 1.6-pymod directory
over the one it usually uses - but how so?
Markus,
Normally this is accomplished as a side effect of running gdal16.bat to
switch to the GDAL 1.6 environment. If you look at osgeo4w\bin\gdal16.bat
you will see it does:
SET PYTHONPATH=%OSGEO4W_ROOT%\apps\gdal-16\pymod;%PYTHONPATH%
A second question that is related to the first one: Is there any way to
check the version of the bindings that have been imported by a script -
anything analogous to "--version" on the command line?
I'd appreciate any help.
The gdal.VersionInfo() function returns the version using GDALVersionInfo().
If no argument is passed "VERSION_NUM" is assumed, otherwise use the
following:
* <ul>
* <li> "VERSION_NUM": Returns GDAL_VERSION_NUM formatted as a string. ie.
"1170"
* <li> "RELEASE_DATE": Returns GDAL_RELEASE_DATE formatted as a string.
* ie. "20020416".
* <li> "RELEASE_NAME": Returns the GDAL_RELEASE_NAME. ie. "1.1.7"
* <li> "--version": Returns one line version message suitable for use in
* response to --version requests. ie. "GDAL 1.1.7, released 2002/04/16"
* <li> "LICENCE": Returns the content of the LICENSE.TXT file from the
GDAL_DATA directory.
* Before GDAL 1.7.0, the returned string was leaking memory but this is
now resolved.
* So the result should not been freed by the caller.
* </ul>
Best regards,
