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.

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

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.

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

Internal development takes place using an in-house GitLab instance. Clone from the internal GitLab and create a branch from 'development-branch'. Push this branch to GitLab and submit a merge request (into 'development-branch') once changes are ready to be reviewed. Once changes have been merged into 'development-branch' push them to GitHub. Merge into master branch before tagging a new release.

External contributions are welcome.

If you have found a bug or would like to suggest new features create an issue providing as much detail as possible.

If you would like to contribute to the code create a fork and make changes into the branch 'development-branch'. Submit a pull request once you are ready for your changes to be merged.
