Abstract
Methods and systems for electronically tracking the progress of teams as they cover an assigned geographic area are described herein. A server computer establishes a coverage area, divides the coverage area into a plurality of regions, and assigns each region to a team. Each team carries a tracking device capable of autonomously determining its present location without user assistance, thus allowing the team to focus on the assigned task, such as searching for a missing person, plowing a field, paving a road, etc. The server monitors the location of each tracking device as each team covers its assigned region, and updates on a visually displayed geographic map a historical path associated with each tracking device based on the monitored location of each tracking device. In this manner, users can quickly view the visual depiction of the historical to determine as yet uncovered areas.
