The modernization of the U.S. Border Patrol necessitated initiatives bringing together the potent mix of geographic imaging, geospatial information systems (GIS), global positioning systems (GPS), infrared aerial photography, and sophisticated sensors for recording activity along the border. Leica Geosystems representatives accompanied U.S. Border Patrol and California Air National Guard into the field. During this field test, the Leica GS5+ Integrated Antennae was mounted on top of a truck, and a data stream was collected and immediately transferred to a laptop inside the truck, running ERDAS IMAGINE® software.
