GEOSPATIAL TECHNOLOGY INCLUDES three different technologies that are all related to mapping features on the surface of the Earth for environmental management. They are geographical information systems (GIS), global-positioning systems (GPS), and remote sensing (RS). This is also synonymous with spatial information technology. Together, the three components of geospatial technology can track, map, analyze, and disseminate environmental management information. RS technology helps survey the entire Earth with unprecedented regularity, thus any environmental change can be noticed. Global atmospheric conditions are monitored on an hourly basis by weather satellites. RS imagery provides information on drought, vegetation, flood damage, forest fires, deforestation, and other natural disasters. GIS provides the tools to accurately map this information in both global and local perspectives. GPS technology accurately tracks the position of environmental fallout. Geospatial information technology can play a vital role in global warming research by ...
