I am working with rasters of forests and need to compute (some) fragmentation index.

I am looking for "single-value" index for each raster. My first try was to do it in QGis but desirable plugin (LecoS – Land cover analytics) is damaged. Also I tried to do it in R and in ImageJ but I can not find any suitable package/plugin or function. I am running out of options.

Can you please recomend some software (Linux preffered)?

what exactly are you trying to calculate? any particular metric? – Paulo E. Cardoso Mar 21 '14 at 10:31
some metric which will reflect the ratio between the area of patches to the length of forest edges of patches. – Ladislav Naďo Mar 21 '14 at 10:37

Do you know [SDMTools Tools](https://www.rforge.net/doc/packages/SDMTools/PatchStat.html)? – Paulo E. Cardoso Mar 21 '14 at 15:53
Thanks! There are many metrics ! PatchID, n.cell, n.core.cell, n.edges.perimeter, n.edges.internal, area, core.area, perimeter, perim.area.ratio, shape.index, frac.dim.index, core.area.index. – Ladislav Naďo Mar 22 '14 at 09:00
