I have clipped buffer area around coordinate from one big raster (forest cover). Such created raster was loaded in R
where PatchStat
function (library SDMTools
) gives fragmentation index.
After detailed look of such created raster I noticed that I have equal classification for non-forest area (0) and corners (also 0).
My question is whether such surplus of empty area make an influence on the value of fragmentation index. I think solution bellow may be helpful, but I do not know how to do it.
