The manner in which wild, free-ranging primates spatially utilize their environment is useful for studies of home ranges, environmental variability, territoriality, climate change effects, ecology, and travel patterns. The emergence of satellite-based technologies including global positioning systems (GPS) and geographic information systems (GIS) has provided an invaluable set of resources with which to track the movement of primates and other animals across vast landscapes with great detail. The strength of these systems, as described elsewhere in this volume, is the increasingly accurate ability to record the use of space by individuals and groups over distances that would be difficult to cover using other technologies. There are circumstances, however, in which satellite-based systems are unnecessary, ineffective, or simply not tenable for use. Most notably, they are problematic when spatial analysis is required within small captive settings such as laboratories, zoos, or sanctuaries.
