overlap

nonoverlap

Special functions to calculate the degree of overlap and
 nonoverlap between trajectories

spatial

Provides classes and functions to calculate various
distance measures and routes in heterogeneous geographic
spaces represented as grids. The package implements measures
to model dispersal histories first presented by van Etten and
Hijmans (2010) <doi:10.1371/journal.pone.0012060>. Least-cost
distances as well as more complex distances based on (constrained)
random walks can be calculated. The distances implemented in
the package are used in geographical genetics, accessibility
indicators, and may also have applications in other fields of
geospatial analysis.
