The current region or computational region is the actual setting of the region boundaries and the actual raster resolution.
As a general rule in GRASS:
- Raster maps are always imported completely at their own resolution (exception: WMS imported layers).
- Raster output maps have their bounds and resolution equal to those of the current computational region.
- In computations, raster input maps are automatically cropped/padded and rescaled (using nearest-neighbour resampling) to match the current region in order to produce the output raster map or to query values.
