    3030Set the region such that it contains all the point cloud data, and the resolution you wish to use – in this case 2.0m:
    3131
    32 2. '''`g.region  n=max_nothing s=min_northing w=min_easting e=max_easting res=2.0`'''
     322. '''`g.region  n=max_northing s=min_northing w=min_easting e=max_easting res=2.0`'''
    3333
    34 replacing the keywords  max_nothing,  min_northing,  min_easting,  max_easting with the values from the `r.in.xyz` command above.
     34replacing the keywords  max_northing,  min_northing,  min_easting,  max_easting with the values from the `r.in.xyz` command above.
    3535
    3636Now we can import the laser point cloud data into grass. This uses the same `r.in.xyz` command as above but without the -s flag:
     
    4848All the separate LIDAR maps can now be patched together to make a single large raster data set. To do this, use the following command:
    4949
    50 5. '''`r.patch in=mapname1, mapname2,... out=lidar_mosaic`'''
     505. '''`r.patch in=mapname1,mapname2,... out=lidar_mosaic`'''
    5151
    5252where the map names are as before, the imported point cloud rasters, and lidar_mosaic is the output name for the single concatenated raster set.
