This page presents the Spatial Individual Specialization Index (SpatIS) and the Spatis Individual Complementary Specialization Index (SpatICS). The two indices were created to assess individual specialization in the use of space by animals and are implemented within R, with support of the packages sp and adehabitatHR.
We present here the documentation of the R functions for running SpatIS and SpatICS using tracking data of individuals. We also present examples on how the indices work. They are based on the appendices of the paper by Kercher-Rogeri et al. (2020). You may find a direct link to the source code in the Github repository in the panel above.
