I try to calculate raster distance to restaurants using proximity in QGIS. I have the following data:
- Binary Int Raster with restaurant location
- Perimeter Shapefile
Using SAGA GIS, I was able to create the Distance Raster, but only in a square defined by the uttermost 1-value pixels. I'd like to calculate in my whole perimeter. In the following image you see the cells (shown as point vectors for better visibility), distance raster and perimeter.
So, how can increase the area of the raster calculation?
