Identification_Information: Citation: Citation_Information: Originator: USDA Forest Service Originator: U.S. Geological Survey Publication_Date: 200212 Title: Forest Cover Types Edition: 3 Publication_Information: Publication_Place: Reston, VA Publisher: U.S. Geological Survey Online_Linkage: Description: Abstract: This data set portrays general forest cover types for the United States. Data were derived from Advanced Very High Resolution Radiometer (AVHRR) composite images recorded during the 1991 growing season, with the exception of Puerto Rico, for which Landsat Thematic Mapper (TM) data were used. A total of 25 classes of forest cover types were interpreted from the AVHRR and TM imagery, aided by field observations and refined with ancillary data from digital elevation models. The data available through the National Atlas of the United States are in GeoTIFF format. This is a revised version of the May 2002 data set, with a corrected shoreline for Greenland. Purpose: The forest cover types data set was developed to portray broad distribution patterns of forest cover in the United States. The data should be displayed at scales appropriate for 1:7,500,000-scale data. No responsibility is assumed by the U.S. Geological Survey in the use of these data. Supplemental_Information: This data set was combined with a shaded relief backdrop to produce a printed map of forest cover types. The original forest type classification was developed by the U.S. Forest Service to accompany a report on forest resources of the U.S. as mandated by the 1974 Forest and Rangeland Renewable Resources Planning Act (PL 93-378). Information on the report, "Forest Resources of the United States, 1997", may be obtained from the U.S. Department of Agriculture Forest Service (). Details on development of the forest cover types data set are in Zhu, Z. and Evans, D.L., 1994, U.S. Forest Types and Predicted Percent Forest Cover from AVHRR Data: Photogrammetric Engineering and Remote Sensing, v. 60, No. 5, p. 525-531.
