Radius of analisis #75

Closed Risi5mora closed 10 months ago

Is it possible to insert a polygonal vector i.e. boundary shape file instead of the radius of analyses?

Hi, no it is not possible. You should use a mask : 1) rasterize your polygon to dimensions of the viewshed raster. 2) use the raster calculator to assign zero to undesired areas

You could show me through a video, it's very difficult to understand through a written message
