r.mapcalcRaster map calculator.
r.mapcalc.simpleCalculates a new raster map from a simple r.mapcalc expression.
r.mfilterPerforms raster map matrix filter.
r.neighborsMakes each cell category value a function of the category values assigned to the cells around it, and stores new cell values in an output raster map layer.
r.quantileCompute quantiles using two passes.
r.textureGenerate images with textural features from a raster map.
r3.mapcalcRaster map calculator.
r3.neighborsMakes each voxel value a function of the values assigned to the voxels around it, and stores new voxel values in an output 3D raster map
t.rast.algebraApply temporal and spatial operations on space time raster datasets using temporal raster algebra.
