This exercise was initially created as a session in a GIS training for the U. S. Fish and Wildlife Service in May, 2016 by Doug Newcomb.

Session Objectives

At the conclusion of this session, you will be able to:

  • Open GRASS GIS and Create a Location from an existing file
  • Link external raster elevation data to the Location
  • Import LAS point cloud data to assess DEM accuracy
  • Import LAS point cloud data to create various vegetation structure products
  • Export raster vegetation structure data layers from GRASS to GeoTiff
