GRASS GIS 7.2.1 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 GPLed), image processing and geographic information system (GIS). Go back to help overview
d.barscale Displays a barscale on the graphics monitor.
d.colorlist Outputs a list of all available display colors.

between two geographic points along a great circle, in a
longitude/latitude data set.
d.graph Program for generating and displaying simple graphics on the
d.grid Overlays a user-specified grid in the active display frame
on the graphics monitor.

d.shade Drapes a color raster over an shaded relief or aspect map.
d.text Draws text in the active display frame on the graphics moni-
tor using the current font.
