Hi Guys,
Hopefully a simple one. I'm trying to create a tab file to support an ASC
ASCII Grid file with the projection coming from a mid/mif. Can anyone tell
me the ogr2ogr or gdal commands to achieve this?
The tab is reasonably simple text file so I could probably hack it with the
mid/mif header
Hi All,
If I know the co-ordinates for all 4 corners of a non-north-up image, how
can I calculate the 6 GDAL affine transform parameters?
Cheers,

think that SetScale (As Frank suggested) would be just as relevant as
SetSpatialFilter or SetAttributeFilter

On your proposal, you say that it would not support REGION, is it normal for
polygons to be recorded as special polylines in DXF (such as from AutoCAD
for example)?
Would it support attributes, such as a DXF of contour lines with elevation
attributes?

perhaps there are others that might also contribute

- What vector sources will be supported (if any) (points only, or polyline
polygon etc)?
- Will it be incorporated in Gdal_Grid?
- When you say regions, do you mean vector polygons or raster zones?

Thanks for that Vincent, very interesting.

Ah, dear, so if I want to frequently change values in TIF file, I basically
can't use compression as the file will quickly get larger than the
uncompressed version. Is this a fair comment?
Also, I've noticed that after 5-8 re-writes of the whole dataset (RasterIO
the whole grid from a buffer),
Hi,
I have a program that is reading and writing to a GeoTif file using Open,
RasterIO and Close calls and Float32 data types.
However, I find that the file just gets larger and larger whenever I write
to the file even though I'm trying to overwrite the existing data. For
example, if open a Tif
