Raster data management

Overview

This section of the tutorial is intended to provide new users with an introduction to raster data management in GRASS GIS. As with other parts of the GRASS 6 tutorial, the examples are largely based on the GRASS 5.7 tutorial as well as the GRASS GIS presentation at Geostat-2012. The aim is to present the reader with introductory information on handling raster data within GRASS GIS.

Data Import

In a similar way to the vector data management, the import and export of raster data is underpinned by GDAL. As such, the modules, r.in.* and r.out.* and specifically, r.in.gdal and r.out.gdal are used. The module r.extenal can be used in lieu of importing a raster into GRASS.

A Geotiff can be imported into GRASS using the command line or the GUI
