NERC-ARF DEM Scripts

About

A collection of scripts developed by the NERC Airborne Research Facility Data Analysis Node (NERC-ARF-DAN; https://nerc-arf-dan.pml.ac.uk) for working with DEMs.

Licensing

This software is available under the General Public License (GPL) Version 3. See the file 'LICENSE' for more details.

Installation

For the scripts to work a number of other software packages, coordinate transform and offset files are also required.

Required Software:

• GRASS
• Python (Needs to be the same version used by GRASS, currently 2.7)
• LAStools (free/paid) - Free tools required for importing LAS files, paid tools can be used to create DTMs/DSMs.

Following installation of these packages, install ARSF DEM scripts using:

python setup.py install --prefix=~/install/path

More advanced functionality (e.g., coordinate transforms) requires additional files and packages.

For more details on installation see installation.

Usage

See the tutorial for more details on creating DEMs from LiDAR data and the scripts page for details on available scripts.
