I'm trying to get the intersection of a Polygon with 2 raster layers in PostGIS.
The rasters have the same size and pixel size and I'd like to retrieve for the polygon a list of something like that:
1; 2
1; 2
1; 3
2; 2
...
Where each line is a pixel intersected by the polygon in both layers and the values is a combination of the pixel value from raster 1 and the pixel value from raster 2.
I don't really know what kind of request I have to do to achieve that...
