JPEG Microsoft Windows XP Version 5.1 (Build 2600) Service Pack 2; ESRI ArcCatalog 9.2.4.1420 Not yet evaluated. unknown N/A Polygon topology present. Work on locating additional perimeters is ongoing. Some perimeters are partial where they cross quad boundaries or the Alaska-Canada boundary, when one or more maps were not located. Some fires may be missing completely if no incident report was located. No formal evaluation conducted. RMS error of map registration when digitizing is no greater than 20 ground meters. No evaluation of true vs. digitized feature position has been conducted. Estimate about +-200 meters since 1980 and up to +- 500 meters prior to 1980. 20 RMS error was restricted to no more than 20 ground meters when digitizing perimeters from source maps. Peimeter mapping methods have varied over time, and the accuracy of the source maps is unknown. Much more emphasis have been placed on accurate fire mapping in recent years. No formal evaluation has been made as to the verticle accuracy of this data.

Fire perimeters from 2007 fire season and previous years were exported from ESRI SDE feature class. 2007 fire season perimeters were collected in various ways: (1) hand drawn by field observers and screen digitized on USGS digital rasters graphics, (2) collected by GPS on the ground or helicopter, or (3) heads-up digitized from various satellite imagery platforms (e.g., Landsat 5, Landsat 7, MODIS). Perimeters were generally collected as shapefiles, then converted to SDE geodatabase feature classes, or heads-up digitized directly into a versioned SDE feature class using on-screen graphics such as satellite imagery. In 2007, approximately 200 previously missing perimeters were discovered and digitized using fire records and/or satellite imagery. Fire records without known perimeters that were previously indicated by 10 meter buffers in earlier releases were removed in this release. Metadata was imported from the 2007 release and modified. http://agdc.usgs.gov/data/blm/fire/index.html 2008 Parker Martyn BLM Alaska Fire Service GIS Specialist mailing address
