摘要：	Geographic information creates unique challenges and opportunities for realizing the mission objectives of the U.S. Army, both in tactical operations and in readiness preparation. It is estimated the Federal Government spends over $3 billion on spatial data in each fiscal year and Geographic Information Systems (GISs) have been implemented at nearly every U.S. Army installation in the United States. In spite of the large investment in digital geographic information and systems, numerous challenges to effective creation, analysis, and delivery of geographic information exist. This research used a combination of theoretical work on the nature of geospatial data quality and a case study to assess the requirements for conducting a data quality assessment. The project develops and tests procedures for performing assessment of the quality of an existing data set (specifically, selected data from the Integrated Training Area Management (ITAM) GIS database in use at Fort Hood, TX). The procedures are intended to be generalizable to other installation ITAM data sets.
