  1. You need to create a DEM from the lidar data to include with the delivery. Use lidar_aster_dem.sh and put the output file in a directory named 'dem'. Noisy points (those with classification 7) should not be included in the DEM (this is the default behaviour). You should also create a second DEM that is suitable for use in aplcor. Use either convert_uk_dem.sh or convert_nonuk_dem.sh depending on where your project is located, or run the script again specifying the different output projection. This DEM should be name ***_wgs84_latlong.dem
