Lee,
I was getting null values when using unprojected data and/or a forced extent. Once I projected my point shapefile, the KDE ran smoothly but each animal ID has a different extent. I need to force the extents to be the same and when I include that in my for loop GME either runs into an ambiguous error or, if it does run, my output is null. Here is my for loop:
for(i in 1:length(ids)){
kde(in="animal_points_prj.shp", out=paste("KDE_",ids,".img"), bandwidth="SCV", cellsize=30,
ext="study_area_prj.shp", where=paste("BirdID='",ids,"'"));
}
Anyone else having trouble forcing the extents across multiple animal IDs? The old Hawth's Tools had a simple button to force extents.
Thanks,
LM
