I have two vector layers: 1) with polygons representing landcover types and 2) a grid, overlapped with the first one.
I want to obtain, for each square within the grid, the number of land cover types. For example:
In the red square it would have 2 landcover types (2 and 7), and the left square to that one only 1 land cover type (2).
How do I obtain this values, using QGIS?
Best Answer
Add a virtual layer (layer > add layer > add/edit virtual layer)
Import both grid- and landcoverlayer
In the query-window you can add following code. In the code you will have to change grid, landcover and type to what your layers and attributes are named of.
Now you should get a new layer with a grid extended by an attribute called 'types'
