Remote Sensing in a Nutshell

According to the National Oceanic and Atmospheric Administration (NOAA), remote sensing is a science that obtains information regarding objects or areas from a distance,  typically using aircraft or satellites to take radar or infrared photography. In 1972, a joint initiative between the U.S. Geological Survey (USGS) and NASA launched the first earth resource satellite (Landsat-1). The Landsat Project is the world’s longest continuously acquired collection of space-based moderate-resolution, land remote sensing data.  The remote sensing data collected has been used by agriculture, commercial, education,  emergency response geology, government, forestry, industry, and military and many other communities.

According to the International Society for Photogrammetry and Remote Sensing (ISPRS), satellite observation has several advantages. It allows users to observe a broad area for a long period, including change detection and invisible information on the electromagnetic spectrum without visiting the area.
