I am trying to overlap the buffer polygons with the 'visible' part of my Viewshed Raster dataset. I have succeeded in doing this. I had to transform my raster data into polygons and then use the intersect tool to see where the buffer and Viewshed polygon overlap.
The situation is sketched here:
Red is in this case the visible part and light blue the buffers. My question is actually if it is possible to calculate the intersection between raster and polygon without transforming the raster data first into polygons?
I am working with the software Arcmap (ArcGIS)
