Final answer:
Remote sensing technology allows geographers to obtain data about the Earth's surface through aerial photographs or satellite images. GPS and GIS are not examples of remote sensing, but they can be used alongside it. GPS provides location coordinates, while GIS integrates and analyzes geospatial data.
Step-by-step explanation:
Remote sensing technology is a method to obtain data about the Earth's surface through aerial photographs taken from airplanes or images created from satellites orbiting the Earth. It allows geographers to identify, understand, and explain the landscape and determine the land use of a place.
GPS and GIS are not considered examples of remote sensing, but they can be used in conjunction with remote sensing to enhance its capabilities.
GPS (Global Positioning System) is a navigation system that uses a network of satellites to determine the precise location of an object on Earth. It provides accurate latitude, longitude, and altitude coordinates. While GPS can collect spatial data, it does not acquire data about the Earth's surface directly like remote sensing does.
GIS (Geographic Information System) is a computer program that integrates, analyzes, and displays geospatial data. It can incorporate data from remote sensing, GPS, and other sources to create specialized maps and perform spatial analysis. GIS enhances the interpretation and visualization of remote sensing data, but it is not a form of remote sensing itself.
