Hi Jan,
Do you mean this : http://www.gdal.org/gdal_datamodel.html (Affine
GeoTransform srection) or this http://www.gdal.org/gdal_tutorial.html
(Getting Dataset Information section)?
Also, see this:
http://www.gdal.org/classVRTDataset.html#a1531325b71e290b90c8d9cc88bce6c2b
Best regards,
Dmitriy

I'm struggling with the order of the Geotransform section in a vrt
file. I would like to rotate an image, and computed the six parameters
for the affine transformation. I can transform points exactly, using
the following formula:
x2 = a.x1 + b.y1 + c
y2 = d.x1 + e.y1 + f
Can anyone tell me what the order is in the GeoTransform section of
the VRT-file?
<GeoTransform> c a b f d e </GeoTransform>
results in an image somewhere in the neighbourhood, but mirrored and
translated. What is the order of the parameters a-f?
Jan
