I'm using QGIS 2.18.26 and I am trying to calculate the home range of howler monkeys I was tracking. Using the AniMove plug in I have managed to produce Minimum Convex Polygons (MCPs). However, I would like to calculate the 'Lacunae' (Contiguous areas within the MCP that were not entered by the monkeys) and am struggling to find information on how to do this in QGIS.

I am attempting to replicate the method used by Ostro et al (1999) in 'A Geographic Information System Method for Estimating Home Range Size' which can be found here--> https://pdfs.semanticscholar.org/72aa/0a32838490a106a3526c9bd017e978134492.pdf

  • Perhaps you can find some method from another home range analysis toolbox geo.uzh.ch/~sstein/ojhorae/horae_documentation_v1.2final.pdf. If not then the authors may be willing to help. – user30184 Aug 12 at 7:05

    That nine-page scientific paper is nice as a supporting document, but please summarize what you're trying to achieve in the body of your question. And please use the full term at least once of any abbreviations you include. – csk Aug 12 at 17:28
