Applied GIS and Remote Sensing

Geographic Information System (GIS) is a system designed to capture, store, manage, analyze, manipulate, and present geographic or spatial data -- satellite remote sensing provides an important source of spatial data

Remote sensing is the process of detecting and monitoring the physical characteristics of an area by measuring its reflected and emitted radiation at a distance (typically from satellite or aircraft). Special cameras collect remotely sensed images, which help researchers "sense" things about the Earth
