What type of data is contained in a GPS receiver database?

The correct answer focuses on the core functionality of GPS receivers, which is primarily to provide navigational data. This includes essential information such as geographic locations, routes, and waypoints that are used to guide users from one point to another. Navigational data is critical for determining the course, estimating distances, and improving overall navigational accuracy.

While topographical maps, weather patterns, and aerial imagery might be associated with various geographic information systems or other related applications, they do not represent the primary data stored or accessed by a typical GPS receiver. The emphasis on navigational data illustrates the GPS’s fundamental role in positioning and guiding users in travel or exploration.
