I have two shapefiles, one containing stream catchment areas, the other information on land cover classes. The problem: I need to know how many percent of the catchment area is covered by forest, grassland and houses.
I read some tutorials and I understand that I need to clip the land cover shapefile so that it fits the catchment shapefile, then I can somehow calculate the percentage of each land cover class.
However, no matter what I try, it does not work. I get empty shapefiles all the time. Could someone explain how to extract the land cover data? I am using QGIS 2.8 on a Mac.
