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 put on in the recent New Mexico wildfires. These maps DOQs (Digital Orthophotoquads) which ar aerial photographs are supplied by the US geologic Survey in Menlo lay California. DOQ images dirty dog also be found on the Microsoft TerraServer situate at http://terra seer.microsoft.com/default.asp These maps allowed firefighters to have a more accurate effigy of the terrain where a fire is burning and where it might spread. On DOQs trees feeling like trees or else then a green shaded vault of heaven on a topographic map. Buildings are more palpable and there square up and possible use can possibly be determined. Becaus e these 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 reap 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 impractical Photography Program (which is ho employ in Sioux Falls, S.D.). like a shot nearly 165,000 DOQs available in the U.S. Because DOQs can serve as a layer in a GIS system, they are peculiarly useful for community and special event syllabusners. Ex. . They were used in Atlanta for the 1998 sum! mer Olympics and are being used to give rise maps for the 2002 Salt Lake City Winter Olympics to layout event sites and plan tape transport 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: OrderEssay.net
