| 摘要： | In spite of the large investments in geographic information systems (GIS) technology and software by the Army and other institutions, implementation has typically occurred in more of an ad hoc manner than preferred, and more decentralized or 'grass-roots' initiated than from a comprehensive information resource management perspective. Some of the problems inherent with this history include insufficiently documented data, redundant and divergently evolving data, incompatible system and file formats, and a disconnect between the capabilities and expectations of a growing user community, and the individuals and organizations historically managing these resources. Enterprise GIS borrows from Enterprise information models used in the broader information systems industry to create a comprehensive framework for providing user information and minimizing problems due to the distributed and disaggregated implementation. This report discusses Enterprise GIS and a comprehensive review of the organization and implementation of systems at an installation to guide future information resource allocations. An installation-wide data model should be developed to identify a common set of data for installation-wide use, collection and attribute standards, accuracy requirements, and maintenance plans (periodicity of updates, notification procedures, etc). User-appropriate interfaces should be developed to minimize unnecessary training or diversion from mission requirements. |
