Differences from the operation
- Runs GDAL's proximity. Targets are non-zero cells unless VALUES lists them; nodata cells are not zero, so on a background of nodata every cell is a target (all distances 0), and with target values listed the background cells get 65535 instead of a distance: give the background as 0.
- UNITS 1 (the default) gives distances in cells, 0 in the CRS's units (set by this mapping).
