v22 v23 30 30 Set the region such that it contains all the point cloud data, and the resolution you wish to use – in this case 2.0m: 31 31 32 2. '''`g.region n=max_no thing s=min_northing w=min_easting e=max_easting res=2.0`'''32 2. '''`g.region n=max_northing s=min_northing w=min_easting e=max_easting res=2.0`''' 33 33 34 replacing the keywords max_no thing, min_northing, min_easting, max_easting with the values from the `r.in.xyz` command above.34 replacing the keywords max_northing, min_northing, min_easting, max_easting with the values from the `r.in.xyz` command above. 35 35 36 36 Now 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: … … 48 48 All the separate LIDAR maps can now be patched together to make a single large raster data set. To do this, use the following command: 49 49 50 5. '''`r.patch in=mapname1, 50 5. '''`r.patch in=mapname1,mapname2,... out=lidar_mosaic`''' 51 51 52 52 where the map names are as before, the imported point cloud rasters, and lidar_mosaic is the output name for the single concatenated raster set.
