[Qgis-developer] Processing with raster files > 4GB

[Giovanni Manghi]

Hi Andreas,

> It may also be an issue with SAGA or GRASS directly.

I have also tested a very large raster (8gb) and SAGA seems to choke
also when used natively from the cli interface.

grass of course does the job, especially when you use the grass data
model from the cli, native grass gui or qgis plugin. Inside processing
large raster suffer from the overhead that is needed to import/export
the raster to, and out of, a temp location.

gdal does the reclass job very quickly and I should be able to add the
tool to processing.

I agree anyway that it too bad that the qgis raster calculator (and
georeferencer) are drawing so little attention. Maybe there isn't much
people that uses them?

cheers!
