SPATIAL ACCURACY: A CRITICAL FACTOR IN GIS-RELATED ACTIVITIES
Citation:
Brilis, G M. SPATIAL ACCURACY: A CRITICAL FACTOR IN GIS-RELATED ACTIVITIES. Presented at Association of Environmental Health Sciences and US Navy Eleventh Annual West Coast Conference, San Diego, CA, March 19-22, 2001.
Impact/Purpose:
The overall objective of this task is to provide the Agency with improved science guidance and strategies for more effective science management and administration.
Description:
Onsite analyses are critical to making timely decisions. The results of these decisions may not be realized for many years. In order to increase the value of onsite analyses and to create and utilize meaningful environmental models, the Environmental Protection Agency (EPA) developed and implemented a Locational Data Policy (LDP).
The intent of this policy is to extend the usage of environmental analyses and allow data to be integrated into GIS systems based upon location, thereby promoting the enhanced use of EPA's extensive data resources for cross-media environmental analyses and management decisions. The EPA Locational Data Policy applies organizations and personnel of agents (including contractors and grantees) of EPA who design, develop, compile, operate or maintain EPA information collections developed for environmental program support.
The EPA's new initiative, the Geospatial Quality Council, is committed to working with all organizations to ensure that spatially related tools, such as the LDP, are supported. An overview of the EPA GIS-QA Team and primary components of the Locational Data Policy will be presented. Internet sites will be provided for future reference.
