I have 1) a point layer and 2) a binary raster file (1 and 0). I need to estimate the Euclidean distance from each point to the nearest "1" pixel. I know there is a tool in ArcGIS but I only have access to QGIS/GRASS; in GRASS there is a clear way to estimate this distance but it's between two vectorial layers (using
So far, I tried:
1) in QGIS, the Proximity tool, but it doesn't give me the result I want, since it considers only one raster layer
2) in GRASS,
r.distance but I get an error ("Raster map is not CELL"), and I am still trying to figure it out, but I'm still not sure which values will it give me since I don't see any option to select a set of pixels ("1", in this case), instead of all the layer
Does anyone know how to do that in QGIS?
