Hi,
I wanna set new field value to an existing shape file which has been opened
with update access, but it doesn't work, my code like this:
OGRFeature* pFeature = pLayer->GetFeature(2);
int nIdx = pFeature->GetFieldIndex("Name");
pFeature->UnsetField(nIdx);
pFeature->SetField( "Name"
Nikos:
Have you checked out any of the new minirasterstrip features in
starspan yet? It takes vector data (any format that OGR supports),
extracts a window (user defined size) around the vector out of a set of
rasters (anything that GDAL supports), compiles it into a single image,
and ref
There has been a lot of discussion lately about using
gdal_translate/gdalwarp with or without the "-co TILED=YES" option,
about overviews and more. How can I determine what is best for my 300
photos? I want faster loading and as less disk usage as possible... what
everybody wants :-)

Apologies for cross-posting.
Can someone tell me why I should NOT use GIMPs "Fuzzy Select" tool to
select various "features" from an image (e.g. orthophoto), save
selection in a new file, add geo-metadata from the original image [1]
and continue my work in GRASS? It works so nice!
Could a tool l
Hi John,
If you can't use use gdal_translate to flatten an existing raster you
can try creating one from scratch using one of the supported language
bindings.
The python bindings work particularly well for this since you can hook
into numpy.
See:

The output for gdal_rasterize has to be an existing geotiff. If I don't
have an existing geotiff for the associated area how can I generate an empty
geotiff based on the extent of the shape file that I will be using as the
source for gdal_rasterize?
Thanks,

Hello,
gdaladdo is having issues with an ENVI file that is 45 GBytes big. I run the
command:
gdaladdo bigfile 2 4 8 16 32 64 128 256 512 1024
The following error message is produced:
ERROR 1: TIFFAppendToStrip:Maximum TIFF file size exceeded
Is gdaladdo supposed to work with files this big? BIG
Hi list,
we are thinking about tagging a version of our ImageIO-Ext project (actually
based on GDAL 1.4.4).
In such a context I would like to know if a date for the release #1.4.5 has
already been estimated.
And what about GDAL 1.5.3?
Thank you very much.
Best Regards,
Daniele Romagnoli
