Abstract: Web Fire Mapper is an internet based mapping tool that delivers locations of active fires in near real time. For selected regions and countries you can view an interactive map showing active fires for a specified time period, combined with your choice of GIS layers and satellite imagery.
Each fire detection represents the center of a 1 km pixel flagged as containing one or more actively burning ... fires within that pixel. The active fires are detected using data from the MODIS (or Moderate Resolution Imaging Spectroradiometer) instrument, on board NASA's Aqua and Terra satellites.
Web Fire Mapper is up dated with additional GIS data and remote sensing layers in collaboration with GOFC-GOLD partners. Web Fire Mapper is primarily aimed at supporting natural resource managers, by helping them understand when and where fires occur.
GIS from the map is available for download. The coverages are in ESRI shapefile and ARC/INFO export files format. Each page contains downloadable arc/info/view data layers in a zip format that is readable by both PC and UNIX machines. Each .zip package contains the .shp, .shx, .dbf, .sbx, and .sbn files that correspond to the product layers. PC users can use PKZIP from &www.pkware.com& to unpack .zip files. UNIX users can use the unzip command. JPEG files are for illustration.
This section of the web site offers users the capability to download GIS shape files from the various Web Fire Maps GIS websites. The coverages are in ESRI shapefile and ARC/INFO export files format.
Web Fire Mapper is updated throughout the day; it takes approximately 4-6 hours after the satellite overpass to process the data and update the website. To find out what time the satellite passes overhead you can check the MODIS orbit tracks via the link on the MODIS Rapid Response Real-time webpage.
