Quizplus · Accepted Answer

Remote sensing involves the collection of data about the Earth's surface from a distance using satellites, spacecraft, or high-altitude balloons. GIS (A) refers to the analysis and interpretation of that data, while GPS (B) is a navigation system that uses signals from satellites to determine location. Aerial photography (D) is a method of capturing images from an airplane or helicopter, but it is not necessarily equipped with specific sensors for data collection. USGS (E) stands for United States Geological Survey, which is a government agency responsible for studying the Earth's natural resources, but it is not a method of data acquisition.
