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.
To start with, have a look at the relevant pages describing the installation procedure, test your install, then read up the User Guide.
For Windows see Installation on Windows (page may be outdated).
If you are a researcher interested in using MDiG, then feel free to firstname.lastname@example.org or send a message to the mailing list. Depending on what you need I may be able to assist you, or you could sponsor development for particular features. Note, any development I do, sponsored or otherwise, will be released publicly and open-source.
Important: these wiki pages are subject to a major revision/update.
- Important: Upgrading
- 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.
Currently MDiG was 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.
