A Global Positioning System (GPS) is a satellite-based navigation system that provides location and time information in all weather conditions, anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. In the context of Advanced Placement Human Geography, it is a critical tool for geographic data collection, analysis, and visualization. For example, researchers may use this technology to map urban sprawl, track migration patterns, or analyze the impact of natural disasters on population distribution.
The significance of this technology in human geography stems from its ability to generate precise spatial data. This enhances the accuracy and efficiency of geographic research, enabling geographers to study spatial relationships and patterns with a high degree of confidence. Historically, reliance on less accurate methods limited the scope of geographic inquiry. The advent of satellite navigation has revolutionized the field, enabling studies of phenomena at various scales, from local community dynamics to global environmental changes. The benefits include improved mapmaking, better resource management, and enhanced understanding of human-environment interactions.
