Abstract

Geospatial Data Standards Development Using Data Model Patterns
Track: Database Design, Automation, and Management
Author(s): Christine Hawkinson, Tom Chatfield

Recently, BLM data architects began to use patterns for developing data standards. A pattern is a business-view of the data which identifies the business rules and common data elements (logical data models for standard business situations). Patterns provide a more effective and consistent development process, and provide the basis for business rules. Once the pattern is approved, it can be used by itself or in combination with other patterns in the design of the physical database and implementation of feature-level metadata. Patterns speed up the standardization process. And the data standards have enabled the new BLM National Geodatabase.

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.
