Description:
Abstract:
The forest type product was created using See5. This software package produces a "confidence" value. According to www.rulequest.com, this confidence value is the confidence with which the prediction is made. The dataset was developed as a collaborative effort between the USFS Forest Inventory and Analysis and Forest Health Monitoring programs and the USFS Remote Sensing Applications Center.
Purpose:
The purpose of this dataset is to provide "confidence" information to the forest type product. The data should not be displayed at scales smaller than 1:63,360.

Other_Citation_Details:
The Forest Inventory and Analysis program of the Forest Service has been in continuous operation since 1930 with a mission to "make and keep current a comprehensive inventory and analysis of the present and prospective conditions of and requirements for the renewable resources of the forest and rangelands of the United States." FIA reports on status and trends in forest area and location; in the species, size, and health of trees; in total tree growth, mortality, and removals by harvest; in wood production and utilization rates by various products; and in forest land ownership. FIA data is protected by the Food Security Act of 1985 as amended (7 U.S.C. 2276(d)), and as such is not publicly distributable.

Title: National Elevation Dataset
Other_Citation_Details:
The USGS National Elevation Dataset (NED) was developed by merging the highest-resolution, best quality elevation data available across the United States into a seamless raster format. NED is the result of the maturation of the USGS effort to provide 1:24,000-scale Digital Elevation Model (DEM) data for the conterminous US and 1:63,360-scale DEM data for Alaska.

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, percent herbaceous cover, and percent bare ground
- MODIS fire points for developed from the MODIS Active Fire Maps
- MODIS 8-day composites
- Multiple dates from the spring, summer, and fall
- All MODIS 32-day composite images that are cloud-free between the years 2001-2003
- Alaska Vegetation Classification

Statistical models developed in Rulequest's See5 data mining software link the FIA plot variables with the imagery and geospatial data. See5 creates classification trees, 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.
