We have create a toolbox for the free GIS software OpenJUMP that allows to analyse movement data, called OpenJUMP HoRAE - Home Range Analysis and Estimation.
About the Home Range Analysis Toolbox
The toolbox contains functions for visualization of movement tracks and allows the creation and analysis of animal home ranges. Home range estimation methods that have been implemented are (see also the article below):
- Minimum Convex Polygon (MCP),
- Kernel Density Estimation (KDE), methods: (a) href, (b) LSCV, and (c) ad-hoc (region split)
- Line-based KDE, scaled and un-scaled
- Brownian Bridges
- Line Buffer
- Local Convex Hulls (LoCoH), methods: radius r, k-1 nearest neighbors, alpha region.
Additionally one can:
- perform an Asymptote analysis for MCP, Point-KDE, Line-Buffer
- Calculate core areas
- Classify home range parts
- derive the Skeleton for a home range region.
- analyze the daily travel
The toolbox was originally developed to analyse location data from grizzly bears (ursus arctos) collected with GPS collars within the Grizzly Bear Programm of the Foothills Research Institute (FRI, Alberta, Canada). Funding was provided by Canadian Phase IV GEOIDE grant (#3).
Download
- download software (package including OpenJUMP 1.4 with the HoRAE toolbox)
- install instructions
- a short article (pdf) that describes the functions of the toolbox (article under submission)
Documentation
We work on a wiki page with some more online documentation.
