GRASS GIS 7.0.4 Reference Manual

Geographic Resources Analysis Support System, commonly referred to as GRASS, is a Geographic Information System (GIS) used for geospatial data management and analysis, image processing, graphics/maps production, spatial modeling, and visualization. GRASS is currently used in academic and commercial settings around the world, as well as by many governmental agencies and environmental consulting companies.

This reference manual details the use of modules distributed with Geographic Resources Analysis Support System (GRASS), an open source (GNU GPLed), image processing and geographic information system (GIS). Go to 3D raster introduction | topics

3d raster commands

r3.colors Creates/modifies the color table associated with a 3D raster map.
r3.colors.out Exports the color table associated with a 3D raster map.
r3.cross.rast Creates cross section 2D raster map from 3D raster map based on 2D elevation map
r3.gwflow Numerical calculation program for transient, confined groundwater flow in three dimensions.
r3.in.ascii Converts a 3D ASCII raster text file into a (binary) 3D raster map.
r3.in.bin Imports a binary raster file into a GRASS 3D raster map.
r3.in.v5d Import 3-dimensional Vis5D files.
r3.in.xyz Create a 3D raster map from an assemblage of many coordinates using univariate statistics
r3.info Outputs basic information about a user-specified 3D raster map layer.
r3.mapcalc Raster map calculator.
r3.mask Establishes the current working 3D raster mask.
r3.mkdspf Creates a display file from an existing 3D raster map according to specified threshold levels.
r3.neighbors Makes 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
r3.null Explicitly create the 3D NULL-value bitmap file.

r3.out.v5d Exports GRASS 3D raster map to 3-dimensional Vis5D file.
r3.out.vtk Converts 3D raster maps into the VTK-ASCII format.
r3.retile Retiles an existing 3D raster map with user defined x, y and z tile size.
r3.stats Generates volume statistics for 3D raster maps.
r3.support Allows creation and/or modification of 3D raster map layer support files.
r3.timestamp Print/add/remove a timestamp for a 3D raster map
r3.to.rast Converts 3D raster maps to 2D raster maps
r3.univar Calculates univariate statistics from the non-null cells of a 3D raster map.
