I'm trying to perform a laborious task to get the class values of a raste overlaid on a multi-part shapefile.
I have a raster with values rated from 0 to 8 for a Main Basin. I also have a shapefile with 3 sub-basins of this main basin.
I would like to calculate the value of the raster classes according to the overlay sub-basin.
For example: shapefile sub-basins: A; B and C. Raster class: 0 to 8
For class 0 what is the area value for sub-basin A?
In QGIS I know there is
r.report, however it only does this for a mono-part shapefile (one polygon).
Would there be any tool in qgis that would do this for multiple polygons?
