GIS, Remote Sensing and Geospatial Sciences
Geographic Information Systems (GIS) help visualize and analyze spatial data—such as points, lines, and areas—along with related labels or data values. Remote sensing involves observing and measuring the physical characteristics of an area by detecting reflected and emitted radiation from a distance, usually via satellites or aircraft. Geospatial science applies information technology to study and understand the relationships between people, places, and Earth's processes.
