QGIS & ECW – A never-ending Story?

ERDAS’ ECW licensing does not allow free redistribution. Therefore, QGIS can’t support .ecw out of the box. However, you can download ERDAS’ SDK – which gives access to .ecw rasters – from their website for free.

If you need ECW support in QGIS and are struggling, you might find Micha Silver’s post “QGIS on Windows with ECW” very helpful.
