AniMov - Animal Movements, A collaborative project
The analysis of animal movement and ranging behaviour (including the estimation of home range size) is a complex issue. A number of programs have been written (see this web site for an incomplete list), but all suffer from one or several limitations, including:
- limited customizability (for ad hoc analyses, change of calculation methods, etc.)
- undocumented calculation methods (crucial especially for kernel analyses)
- limited or no interaction with Geographic Information Systems (GIS)
- the need to purchase proprietary, expensive software
We believe the problem could be solved by the use of several free and open source programs:
- the statistical program R for calculations (kernel, minimum convex polygon, etc.)
- Quantum GIS and GRASS for GIS analyses and display
- optionally, PostgreSQL for data storage, selection and retrieval
All software is available both for GNU/Linux, Mac OSX and MS Windows operating systems. We aim at producing the most advanced software; our indicative term of reference is Animal Movements (which requires the expensive, obsolescent, and proprietary ArcView + Spatial Analyst proprietary packages).
All resulting software is and will be freely available (under GPL or similar licences).
The QGIS plugin to compute Home Ranges at work. Available methods are: MCP, kernel h LSCV, kernel h REF, kernel with adjusted h and NNCH
Where have we got?
Quite far indeed! It is now possible to run sophisticated kernel, minimum convex polygon, and local nearest-neighbor convex-hull analyses from an entirely graphic GIS environment. See our collaborative page for updates. We also maintain a web page with instructions to set up the system and run the analyses.
Join the group!
AniMove lives thanks to the efforts of many people, which contributed through time. Your help would therefore be much appreciated. This could be a suitable project for a MSc thesis. You can collaborate by testing the software, writing manuals and other info on our collaborative pages (wikis: State of the art, HowTo, Wishlist), and writing code. Please subscribe to the mailing list or write us if you are interested.
