> Dear all

> I am working on a 3D home range estimator, we want to calculated home ranges and core areas on primates that were followed sleeping site to sleeping site. We collected GPS locations and animals height at equal intervals along the day. 
> We already calculates home ranges and core area in 2D using Delaunay triangulation and then applying a hot spot analysis in ArcGis( Getis Ord G*) using the perimeter of the triangles. Then, to calculate it on 3D we first created a 3D convex hull formed by tetrahedrons using animals locations (coordinates in meters)  and height.

> we are wondering if it is possible to use the function Local G or Global G test (package Spdep) for 3D locatios (X,Y,Z) as we previously  did in 2D (Hotspot with rendering, ArgGis)

Thanks in advance
