Level: Data Management - Intermediate

The implementation of geospatial data layers within the Bureau of Land Management (BLM) requires the development of data standards to enable them to become ‘National Data Layers’. These standards are needed so that internal and external users such as the public have a consistent and shared understanding when using the information. The BLM National Geodatabase would not exist without data standards, and patterns provide a more effective and consistent development process.

BLM data architects use patterns (data models for standard business situations) for developing data standards. These patterns are then used to design the physical database and implement feature-level metadata. As an example, we will use one of the first patterns developed, Boundary. We will discuss how this pattern is being reused for other BLM Boundary layers and how it is advancing the development of geospatial data standards across our organization.
