Process_Step:

Process_Description:

The methodology used to produce the national forest type database combined ground-truth (from FIA plot data) with multi-date imagery and variety of other spatially continuous geospatial data. The predictor data themes include,

- Elevation, slope, and aspect - Unified Ecoregions - MODIS Vegetation Indices such as EVI, NDVI. - MODIS Vegetation Continuous Fields - Percent tree cover - MODIS fire points for developed from the MODIS Active Fire Maps - MODIS 8-day composites - Multiple dates from the spring, summer, and fall.

Statistical models developed in Rulequest's Cubist data mining software link the FIA plot variables with the imagery and geospatial data. Cubist creates rulesets, which have the advantage of not assuming parametric properties within the predictor data and are thus are more appropriate for the multi-scale, multi-source data, which are being used.
