US Forest Service - FIA Forest Types (Generalized) of the Southeastern United States
Dataset Identification:
Resource Abstract:
This dataset portrays 61 forest group types across the southeastern United States. These data were derived from a product
created by the USFS Forest Inventory and Analysis (FIA) program and the Remote Sensing Applications Center (RSAC). Â The
original dataset (accessible from the <a href="http://svinetfc4.fs.fed.us/rastergateway/forest_type/index.php">US Forest Service
Website</a>) consists of 141 forest types across the contiguous United States. <br /> <br /> The original dataset was downloaded
on 12/13/2013, clipped to the southeastern states, Â and used in a generalization procedure which involved the
application of a majority filter (8 neighbors, half replacement threshold) followed by a sieving process which removed pixels
in groups of four or less by reassigning them to their nearest neighbor value. <b><br /><br /><br />Abstract: </b> <br />
<br /> This dataset portrays 141 forest types across the contiguous United States. These data were derived from MODIS composite
images from the 2002 and 2003 growing seasons in combination with nearly 100 other geospatial data layers, including elevation,
slope, aspect, ecoregions, and PRISM climate data. 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. <br /> <br />
<b>Purpose: </b> <br /> <br />The purpose of this dataset is to portray broad distribution patterns of forest cover in the
United States and provide input to national scale modeling projects. The data should not be displayed at scales smaller than
1:2,000,000. Independent accuracy assessments were conducted using a 10% holdout of the training data, and are available through
the data source contact. <br /> <br />Complete metadata is available on the <a href="http://svinetfc4.fs.fed.us/rastergateway/forest_type/conus_forest_type_metadata.php">USFS
website</a> in HTML format.
