2006 fires were updated using the UPDATE command using data by Jay Miller or RSAC; from same year imagery change to one year or more after fire imagery change (i.e. ChgTimePeriod from value 1 to value 2).

Fire names adjusted to all upper case, and uniform names used in replacement of multiple sources fire names. Any spelling errors corrected. Dissolved to create NWFP_Fire Severity94_07v2

All sources were clipped using the California Northwest Forest Plan Boundary layer.
The Interagency Fire History (perimeters) - up to and including 2007 layer was used to select all fires from 1994 to 2007 within the Northwest Forest Plan boundary. Only selected fields from this layer were retained.
Field 'ChgTimePeriod' added to reflect the period of time between time one and time two imagery layers used in the various change detection projects (i.e. value 5 was used to reflect the 5 years between image dates for ChangeDet94_98, 2 was used for VegSeverity07 and some RSAC data to show a year had passed between image dates, and 1 was used for recent fire severity data just processed quickly with imagery from the same year.
Added six fires retrieved from RSAC FTP site: <ftp://fsweb.rsac.fs.fed.us/RAVG/California/> 1999lowden_b_ba4class.img 2000cabbage_b_a4class.img 2004irongate_b_ba4class.img 2005deer_b_ba4class.img 1996fork_b_ba4class.img 2005wooley_b_ba4class.img

From USGS Monitoring Trends in Burn Severity (MTBS): CA-SHU-00000338-19940712, bs_comb_g and No Change (1). FireHistory07 features were updated using the UPDATE Command, the change detection and veg burn severity with value 0 was placed where no update occurred in the "Severity" field, to reflect 'no severity data'. MTBS data required re-projecting to Teale Albers NAD83.
Grid data was converted to feature classes and re-projected as necessary. Change Detection data values 70-100% decrease, 40-70% decrease, and 15-40% decreases in vegetation cover were crosswalked to fit the categories of high (4), moderate (3), low (2), and no change (1) values. Vegetation Burn Severity values are recorded in the field "Severity" following that domain value system, High (4), Moderate (3), Low (2), Unchanged (1)
Severity and Source were added and populated. All fire severity sources were appended into one geodatabase and updated into fire perimeters from the FireHistory07 layer.
