This page explains how to work with external data in GRASS 7.
(to be expanded)
Raster data
External raster data can be linked via r.external. List of supported formats can be determined by
r.external -f
To link file-based data formats, eg. GeoTiff
r.external input=ncrast/urban.tif output=urban
Vector data
External vector data can be linked via v.external. List of supported formats can be determined by
v.external -f
To link file-based data formats, eg. ESRI Shapefile
v.external dsn=ncshape/ layer=railroads output=railroads
Assuming that 'railroads.shp' is located in directory 'ncshape'.
Using wxGUI
From menu
File -> Link external formats
or from toolbar in Layer Manager.
