Modular Dispersal in GIS (or MDiG) is a framework for modelling the spread of a species' population distribution through time. The software is built upon the powerful open-source GIS platform GRASS and provides a simulation manager that can automate analysis across replicates and occupancy maps. A web interface is currently being funded by the New Zealand Bioprotection Centre of Research Excellence.

Get MDiG

MDiG is in active development, and due to currently being the only frequently active user/developer, I haven't had the chance to package up a recent version for easy use. Instead, you'll have to grab the code from here using the version control system called Bazaar:

The following command will download the latest development version of the code:

> bzr branch lp:mdig

If you are a researcher interested in using MDiG, then feel free to contact me. Depending on what you need I may be able to assist you, or you could sponsor development towards a release for your platform. Note, any development I do, sponsored or otherwise, will be released publicly and open-source.

Documentation

• Important: Upgrading
• Install guides:
  • Installation on Linux
  • Installation on Windows
  • Installation on OSX
• User Guide - covers how to create a model file, configuration of MDiG, running and analysis.
• Cookbook - How to carry out various tasks that often come up in relation to MDiG, GRASS, and dispersal models.

Development

Currently MDiG has been developed as part of my PhD research at Lincoln University. Although I somewhat maintain MDiG, most of my time is spent on applying the model to case studies for contract work. I'll try and fix bugs and develop the software further as I get the chance. Users should submit bugs on the open-source developer site Launchpad.

• Redesign of MDiG - A number of major reworkings that would improve MDiG, now that it's use and functionality is better defined.
• Todo List
• Parallel processing - plans for client server operation.
• Filesystem layout - Description for the new layout of MDiG related files.
• Version History - List of changes/features from version to version.
