U.S. Forest Service 20170504 vector digital data GTR WO-76 Washington, DC USDA - Forest Service The data sets were created using the PRISM climate mapping system, developed by Dr. Christopher Daly, director of the Spatial Climate Analysis Service (SCAS). More information about the data sets may be obtained through the PRISM Climate Group web page, http://prism.oregonstate.edu/. PRISM stands for Parameter-elevation Relationships on Independent Slopes Model. USDA - Forest Service ECOMAP Team 20170504 vector digital data Washington, DC USDA - Forest Service The Climate Subsections feature class contains ecological subsection polygons attributed with climate information to show the relationships between ECOMAP 2007 and various climate data from the PRISM climate mapping system. The EcomapSubections 2007 data set describes the ecological subsections within the conterminous United States. It contains regional geographic delineations for analysis of ecological relationships across ecological units. ECOMAP is the term used for a USDA Forest Service initiative to map ecological units and encourage their use in ecosystem-based approaches to forest land conservation and management. This is a collaborative effort with many partners. It is coordinated at the national and regional levels by USDA Forest Service staff and implemented in cooperation with State forestry agencies and others. ECOMAP mapping criteria are outlined in the National Hierarchical Framework of Ecological Units (https://www.ncrs.fs.fed.us/gla/reports/hierarchy.htm). The framework systematically divides the country into progressively smaller areas of land and water that have similar physical and biological characteristics and ecological processes. The purpose of the Ecomap Sections and Subsections data sets is to provide a baseline map of the ecological boundaries. The data can be used for ecological analysis of resource distribution patterns and associations among different ecological land units 20070101 publication date Complete As needed -124.762615 -66.798038 49.386392 24.530689 None precipitation temperature ecoregion PRISM subsection frost free climate ecomap relative humidity ISO 19115 Topic Categories climatologyMeteorologyAtmosphere geoscientificInformation None United States None The USDA Forest Service makes no warranty, expressed or implied, including the warranties of merchantability and fitness for a particular purpose, nor assumes any legal liability or responsibility for the accuracy, reliability, completeness or utility of these geospatial data, or for the improper or incorrect use of these geospatial data.
