Lionel,
Most the data you asked for can be obtained with various methods from the
GDALDataSet and GDALRasterBand objects. I'm not sure what you mean by units
type , but I'm sure it can be derived from them.
FYI, reference pixels are called GCPs (Ground Control Points) in GDAL. Datum

Hi folks, I'm a new GDAL developer with what I believe is a simple question:
We're trying to use GDAL in our app to access Envi files. I'm able to get
access to the file bands as well as some other information by using the
GDALDataset and GDALRasterBand objects, but how can I access other

PGeo support depends on a working ODBC driver for MDB databases. On Linux,
this is done with mdbtools. I have not been able to get this working on OS X
with the system iODBC (I last looked at it a year ago). It compiles (with some
hackery), but does not load. I haven't tried mdbtools with Un
Thank you for your reply. I played around a little bit but without success.
When I apply val_repl.py to the data, it appears to cut off all the higher
elevations while the lower areas remain untouched. So the resulting TIF is
unusable. What could cause this problem?

Hello,
I see that OGR supports reading ESRI Personal Geodatabases. We are
considering adding this capability to our product, which has both Windows
and Mac OS X implementations. I have tried the basic functionality on
Windows (using FW_Tools), and the OGR documentation has instructions for

How to compile gdal against a user specified numpy
I THINK the GDAL build calls python distutils (setup.py) to do the
actual python extension build.
Ideally, the setup.py uses
numpy.get_include() to get the numpy include directory.
If so, it should "just work" with your setup

Martin,
Generally speaking it is not safe to have multiple threads making calls
into a single OGRLayer at the same time. At the very least you will
encounter the "messing up" effect on GetNextFeature(), eve
