The attributes were checked against the original source for accuracy.
The polygons have been checked for dangling lines and closure. This theme is built for polygon topology.
This theme covers both public and private lands in the western portion of BLM Salem and Eugene Districts, and a small portion of the northern half of BLM Roseburg and Coos Bay Districts.
Fire history Maps
Polygons and Attributes
The fire history map was digitized in ADS by BLM contractors. The ADS map was then translated into MOSS and plotted for QC against the original map.
MOSS map of the fire history was translated into ARC by use of the MOSSARC command. Then the theme was inserted into the Q100 library.
The Q100 Library was converted from Arc/Info ver. 6.1.2 to Arc/Info ver. 7.0.3.
