I'm trying to install and use GDAL in Python, and there seems to be
something very fundamental that I'm missing.
To start with the problem... In a new python file I write:
try:
fromosgeo importgdal
exceptImportError:
importgdal
When run it replies:
Traceback (most recent call last):
_File "C:\Martin\Work_Eclipse\Hilfe\src\check_GDAL.py", line 8, in <module>_
import gdal
ImportError: No module named gdal
To me that translates into, Python can't find the GDAL modules.
I'm running on a win-xp computer, I use python 2.6 as I recently
upgraded to ArcGIS 10. Before that I used GDAL with Python 2.5 (and
ArcGIS 9.x) that worked just fine.
I have no problems calling other Python add-ons, e.g. numpy.
I using GDAL from http://pypi.python.org/pypi/GDAL/
I downloaded http://download.osgeo.org/gdal/win32/1.6/gdalwin32exe160.zip
After unzipping to a dir of my choice I included the .../bin dir in my
'path' and created a 'GDAL_DATA' environment variable pointing to .../data
It then looks like this:
C:\>echo %PATH%
C:\WINDOWS\system32;...<shortened>...;C:\APPS\PRO\gdalwin32-1.6\bin
C:\>echo %GDAL_DATA%
C:\APPS\PRO\gdalwin32-1.6\data
As I read the installation guide it should do it -- but it doesn't, as
the code sample above indicates.
Though not mentioned in the installation guide, I also created an
environmental variable PYTHONPATH, including the .../bin directory
C:\>echo %PYTHONPATH%
C:\APPS\PRO\gdalwin32-1.6\bin
Unfortunately this makes no deference to the program.
*Question 1*: Are there any problems in using GDAL 1.6 with Python 2.6
on a win-xp?
Looking into ...\gdalwin32-1.6\bin\ in find no *.py files (nor *.pyc)
I would have expected some files with python extensions.
I also expected a file with the name 'osgeo.*' or 'gdal.*', since this
is what the Pyhon import statement try to import. Alternatively a .zip
file with such files inside. But non of that is in the
...\gdalwin32-1.6\* to be found.
*Question 2: *Am I missing something here? How is this binding supposed
to work? What file exactly is the import statement supposed to find,
that will enable it to include osgeo functionality?
Best Regards
Martin
