Hi List,
I have a raster file DTM (altitude attribute in the pixels). I reclassified
this raster in 4 classes of altitude and I need to calculate for each
class  the area (in how many square meters is each different class
I can for example transform the raster file reclassified into a vector file
and calculate the area, but is it possible to do without any
vectorialization and so directly calculating it from the raster file?

 Thanks, Azzurra
