hi etienne, it seems that compression is also possible via GUI

I know (I did part of it) - but it's not available for all tools... For
example, the Translate tool has it, but not the Warp tool.
Perhaps it would be easier to add to all the tools if it were part of the
default tool interface (which shows the command line etc.)

Thank you Eric,
I had to chose FME to save the ECW. My third party software supports other
formats, but TIFF files are huge, so it is not a viable solution.

Hi Asher,
Sorry, I didn't read the full GDAL page regarding ECW
Hi Asher,
GeoTIFFs can be compressed considerably but they still end up a bit larger
than ECW's.
For example we have aerial photography:
ECW: 22.7GB
JP2: 26.4GB
GeoTIFF: 31.2GB
So the GeoTIFF (actually an image pyramid) is about 50% larger, but is also
better quality and faster loading.
Cheers,
Eric,
I just tried to create a VRT from all ecw images in a folder.
Unfortunately, it does not work, the command line seems to be rejected when
there are too many input files. The problem also appear if directly using
the gdalbuildvrt from the command line. The only solution I found was to
build
Hi all,
I have a set of more than 200 ecw rasters that I can easily load in QGIS. I
also have a vector polygon layer which bounds an area covering a part of
the area covered by the whole set of rasters. What I would like to do is to
extract only, the raster which are intersected by the vector
Hi asher, if you go to raster - miscellaneous, there is a menu entry
called build virtual raster catalog. You can use that to virtually mosaic
all of your ECW files. This tool creates a new file you can load in as a
raster that references all of the individual ECW files to display them
seamlessly
Yes, you should be able to choose ECW from the files of type drop down in
the output file selection dialog and select ECW.

Thanks Eric, sounds really good. Is there a way to save the resulting file
