I have a soil sealing fraction map (SSF) with a resolution of 30 meters and a high resolution land cover map (HRLC) with a resolution of 5 meters. I would like to use the HRLC map to filter some classes out of my SSF.
What is the best way of aggregating the land cover map to a lower resolution in order to do this ?
Or is it better that I resample my SSF to 5 meter resolution, filter out the classes, and aggregate the map to 30 meters again ?
EDIT : I want to filter out roads by this technique. So my second option won't work without corrupting the pixels next to roads.
