GIS in Fighting Wild heightens Recently there has been an invasion of wildfires end-to-end southern California, brisk Mexico and Florida. GIS and the USGS select come to the facilitate of firefighters contend these wildfires. New digital maps that atomic number 18 the combination of aerial photographs and the geometric qualities of a map were design in the recent New Mexico wildfires. These maps DOQs (Digital Orthophotoquads) which ar aerial photographs argon supplied by the US geologic Survey in Menlo parkland California. DOQ images digest also be found on the Microsoft TerraServer land site at http://terra seer.microsoft.com/default.asp These maps allowed firefighters to have a more accurate foresee of the terrain where a fire is burning and where it might spread. On DOQs trees count like trees or else then a green shaded land on a topographic map. Buildings are more megascopic and there square up and possible use can possibly be determined. Because the se maps were in high demand during the wildfire, these maps were delivered electronically, downloaded and printed by the recipient, thus speeding up the process of determining a way to mend these fires out. This is in sharp contrast to a time when topographical maps had to be updated by hand scribers and printed on special presses. USGS began producing these maps in 1991.

Images are derived from the archives of the National aerial Photography Program (which is ho employ in Sioux Falls, S.D.). at present nearly 165,000 DOQs available in the U.S. Because DOQs can serve as a layer in a GIS system, they are especi ally useful for community and special event ! syllabusners. Ex.. They were used in Atlanta for the 1998 summer Olympics and are being used to induce maps for the 2002 Salt Lake City Winter Olympics to layout event sites and plan transferee corridors. With USGSs DOQs New Mexico was able to contain one of there... If you destiny to get a full essay, order it on our website: OrderCustomPaper.com
