Abstract
 Development of Data Standards for a Large Government Bureau Track: Federal Systems Implementation Author(s): Thomas Chatfield, Barb Kett Enterprise GIS implementation within the Bureau of Land Management (BLM) has required the development of data standards for themes as they become "National Data Layers". As with many organizations, GIS technology within the BLM developed over time in a distributed environment. Creation of data standards during that time was limited by the lack of a centralized IT organization. Within the Enterprise Architecture, the BLM is establishing national standards for geospatially enabled data. The BLM has created processes for data standards development for all types of data, whether spatially enabled or not. The process normally calls for consensus on a logical data model (LDM). Recognition of the difference of spatially enabled data occurs with the identification of geospatial features and the relationships between those features within the LDM. The standards process is completed by creating physical database models based on logical models and business rules, and implementation of Feature Level Metadata.
