Bug report #13408

Graphical Modeler Raster layer Input does not recognize GRASS raster file

Affected QGIS version:2.8.3 Regression?:No

Pull Request or Patch supplied:No Resolution:duplicate
Crashes QGIS or corrupts data:No Copied to github as #:21457


In a created model using the Graphical Modeler, the model will not recognize/allow use of a GRASS raster layer as a Raster layer input. The GRASS raster layer has been added to the QGIS project, but it does not appear as an input option to use in the Raster layer drop-down list of the model. GRASS vector layers are recognized/allowed, and work fine, as Vector layer inputs for the model.

Not a bug. Grass raster layers are not supported as inputs for Processing algorithms

Thank you for the information. When using the GRASS tools available in the Processing Toolbox, I am able to use GRASS raster layers as input layers; so it seems that the functionality to accept GRASS raster layers as input files is already in QGIS. With the raster processing capabilities of GRASS, and with there being 100+ GRASS raster processing tools in the toolbox, the ability to create Processing algorithms/models that include these powerful tools would be a worthwhile feature to have in QGIS.

(on Windows and Linux GRASS raster layers are not yet shown as available inputs, when it will then is expected them to work in any place in Processing).
