Geographic information systems (GIS) technology can be used for scientific investigations, resource management, and development planning. For example, a GIS might allow emergency planners to easily calculate emergency response times and effected areas of the ocean during an oil spill based on the spills location. You may ask, what is GIS?

AVHRR is only one of many sensor systems used for Earth surface analysis. More sensors will follow, generating greater amounts of data. With this type of technology, scientist not only have the resources to help preserve our earth, they also have the proof of destruction at a global scale derived from GIS.
