| 4 | == Module behaviour: computational region settings == |
| 5 | |
| 6 | The current region or [https://grasswiki.osgeo.org/wiki/Computational_region computational region] is the actual setting of the region boundaries and the actual raster resolution. It can be considered as region of interest (ROI). |
| 7 | |
| 8 | As a general rule in GRASS GIS (new module implementations should follow this!): |
| 9 | * '''Raster maps''' are always imported completely at their own resolution (exception: WMS imported layers). |
| 10 | * '''Vector maps''' are always imported completely. |
| 11 | * In computations, |
| 12 | * 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. |
| 13 | * Raster output maps have their bounds and resolution equal to those of the current computational region. |
| 14 | * Vector maps are always considered completely. |
