## NAME

r.external

## DESCRIPTION

r.external allows a user to link a GDAL supported raster file to a binary raster map layer, from any GDAL supported raster map format, with an optional title. The file is not imported but just registered as GRASS raster map.

## EXAMPLES

### RGB Orthophoto from GeoTIFF

    # import of all channels:
    r.external  /home/user/data/maps/059100.tif out=ortho
    g.region rast=ortho.3 -p
    d.rgb r=ortho.1 g=ortho.2 b=ortho.3
    r.composite r=ortho.1 g=ortho.2 b=ortho.3 output=ortho.rgb
