Agus,
Given a vector map (i.e., a land cover map)
and a raster of a continuous variable (i.e., height),
is there any plugin calculating a table of average
(and perhaps other stats) of the raster for
each category in the vector?
I don't know of any plugins that will do this directly, but here is one
possible solution:
If you are able to convert your raster to points (i.e. extract the
centre of each raster cell as a point), then you could use the 'Join
attributes by location' tool in fTools to extract the info that you need
(and you can opt to calculate the mean values).
Hope this helps,
Carson
