GRASS GIS 6.0.1 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 GPL'ed), image processing and geographic information system (GIS).

How to start with GRASS

display commands: d.ask Prompts the user to select a GRASS data base file from among files displayed in a menu on the graphics monitor. d.barscale Displays a barscale on GRASS monitor. d.colorlist Output a list of all available display colors with a configurable separator (default is comma). d.colors Allows the user to interactively change the color table d.colortable To display the color table associated with a raster map layer. d.erase Erase the contents of the active display frame with user defined color d.extend Set window region so that all currently displayed raster, vector and sites maps can be shown in a monitor. d.font.freetype Selects the font in which text will be displayed on the user's graphics monitor. d.font Selects the font in which text will be displayed on the user's graphics monitor. d.frame Manages display frames on the user's graphics monitor. d.geodesic Displays a geodesic line, tracing the shortest distance between two geographic points along a great circle, in a longitude/latitude data set. d.graph Program for generating and displaying simple graphics to the graphics display monitor. d.grid Overlays a user-specified grid in the active display frame on the graphics monitor. d.his Displays the result obtained by combining hue, intensity, and saturation (his) values from user-specified input raster map layers. d.histogram Displays a histogram in the form of a pie or bar chart for a user-specified raster file. d.info Display information about the active display monitor d.legend Displays a legend for a raster map layer in the active frame on the graphics monitor. d.linegraph Generates and displays simple line graphs in the active graphics monitor display frame. d.m d.mapgraph Generates and displays simple graphics on map layers drawn in the active graphics monitor display frame. d.measure Measures the lengths and areas of features drawn by the user in the active display frame on the graphics monitor. d.mon To establish and control use of a graphics display monitor. d.monsize Selects/starts specified monitor at specified size d.nviz Create fly-through script to run in NVIZ d.out.png Saves active display monitor to PNG file in home directory d.paint.labels Displays text labels formatted for use with GRASS paint (p.labels, p.map) output to the active frame on the graphics monitor. d.path Find shortest path for selected starting and ending node d.profile Interactive profile plotting utility with optional output. d.rast.arrow Draws arrows representing cell aspect direction for a raster map containing aspect data. d.rast.edit d.rast.edit d.rast Displays and overlays raster map layers in the active display frame on the graphics monitor. d.rast.leg Displays a raster map and its legend on a graphics window d.rast.num Overlays cell category values on a raster map layer displayed to the graphics monitor. d.redraw d.redraw d.resize Resizes active display monitor d.rgb Displays three user-specified raster map layers as red, green, and blue overlays in the active graphics frame. d.rhumbline Displays the rhumbline joining two user-specified points, in the active frame on the user's graphics monitor. d.save Create a list of commands for recreating screen graphics. d.slide.show Slide show of GRASS raster/vector maps d.split Divides active display into 2 frames & displays maps/executes commands in each frame. d.text.freetype Draws text in the graphics monitor's active display frame using TrueType fonts. d.text Draws text in the active display frame on the graphics monitor using the current font. d.title Outputs a TITLE for a raster map layer in a form suitable for display by d.text. d.vect.chart Displays charts of GRASS vector data in the active frame on the graphics monitor. d.vect Displays GRASS vector data in the active frame on the graphics monitor. d.what.rast Allows the user to interactively query the category contents of multiple raster map layers at user specified locations within the current geographic region. d.what.vect Allows the user to interactively query a vector map layer at user-selected locations within the current geographic region. d.where Identifies the geographic coordinates associated with point locations in the active frame on the graphics monitor. d.zoom Allows the user to change the current geographic region settings interactively, with a mouse.
