How are GPS and GIS related?

GPS, or Global Positioning System, is a technology that provides precise location data based on satellite signals. This spatial data includes latitude, longitude, and altitude information, which can then be utilized within a Geographic Information System (GIS). GIS is a framework for gathering, managing, and analyzing geographic data, allowing users to visualize and interpret spatial information. By providing foundational data about locations and positions, GPS plays a vital role in the input layer of GIS.

In practical applications, GPS data can be used to map phenomena, track movements, and conduct analyses that reveal patterns over specific areas. For instance, when conducting environmental studies, GPS devices can collect data points that GIS can then layer onto maps for better understanding and visualization, thereby enhancing decision-making processes.

The other choices highlight aspects that are either incorrect or misrepresent the relationship between GPS and GIS. For instance, GPS is not a subset of GIS, but rather a complementary technology that feeds data into GIS for processing. Additionally, while GIS does provide valuable data, it does not enhance GPS accuracy; instead, it utilizes the accuracy of GPS data. Finally, GPS does not prevent the misuse of GIS technology; rather, responsible use of both systems is essential in any navigational context.
