DESCRIPTIONModule r3.gradient computes gradient from a 3D raster map. Results are three 3D raster maps describing the x, y, z components of the computed gradient field.EXAMPLES# create a 3D raster g.region s=0 n=100 w=0 e=100 b=0 t=100 -p r3.mapcalc "test_gradient = sqrt(row()*row() +col()*col()+ depth()*depth())" # compute gradient r3.gradient input=test_gradient output=grad_x,grad_y,grad_z SEE ALSOr3.flow, r.flowAUTHORSAnna Petrasova, NCSU OSGeoREL, developed during GSoC 2014.SOURCE CODEAvailable at: r3.gradient source code (history)Main index | 3D raster index | Topics index | Keywords index | Graphical index | Full index © 2003-2021 GRASS Development Team, GRASS GIS 7.8.6 Reference Manual
