To minimize
losses from fires, organizations involved in fire management need to actively
manage fire risk by mapping existing fuels. Sanborn applies cost-effective remote
sensing and GIS technologies to develop surface fuels model maps at the Wildland,
Urban Interface and Urban levels. By targeting areas of high risk and loss potential,
and identifying the actual sources of hazards, Sanborn can provide consistent
and up-to-date methodologies for aggressive fuel management programs. Fuels
are traditionally mapped to Fire Behavior Prediction System (FBPS) fuel models.
There are a total of 13 fuel models that fall within four basic groups: grass,
chaparral and shrub, timber, and slash. Wildland fuels are mapped using Landsat
TM imagery (30 meters) as a baseline. Optionally, high-resolution multispectral
imagery can be used to map Urban Interface and Urban fuels at 4-meter resolution
or better. The enhanced spatial mapping resolution of fuels in the Urban Interface
affords better delineation of urban features such as property and buildings. Both
aerial and satellite data acquisition options are available depending on the resolution
and geographic extent of the assessment. The automated classification
scheme takes into consideration the following factors: - Vegetation
cover type or species composition
- Vegetation structural or stand
development stage
- Crown closure or percent vegetation cover
- Slope position
- Shaded relief
- Topography
- Population density
