Understanding Geospatial Data Rules in the Platform Independent Model (PIM)

This post continues a series describing our approach to using a platform-independent approach to managing data models and standards. In any situation where a geospatial data model is agreed upon and adopted by multiple participants, management of the model itself becomes a significant issue. Over time, modifications to the model are required. Such modification can […]

Applying Flexible, Yet Standard, Geospatial Conventions

Previous posts have touched the problems that traditionally face those wanting some geospatial consistency in data collection, data presentation, and data understanding. These issues drive much of the continual interest and push for increased Metadata and many of the “Use Liability” clauses that are attached to current datasets. After all, if you don’t really know […]

Expanding Usefulness of Geospatial Data Standards

Background: While many organizations see the clear advantages of establishing and using geospatial data standards, obtaining compliance from constituents continues to be a frustrating, and costly, problem. Users are frequently reluctant to adopt a new standard given the potential cost of modifying applications that use an existing, custom schema or simply having a ‘not invented […]

Understanding SDSFIE 3.0 Compliance

One of the more critical, and somewhat confusing, concepts in the SDSFIE 3.0 is the notion of what constitutes a ‘compliant’ data set. SDSFIE 3.0 offers considerably more flexibility in schema options than earlier releases. This capability was created to permit individual DoD users some naming options to accommodate existing legacy applications that use geospatial […]

Spatial Data Standards for Facilities, Infrastructure and Environment (SDSFIE): Five Fundamental Tools

The Spatial Data Standards for Facilities, Infrastructure and Environment (SDSFIE) is the single Department of Defense spatial data standard that supports common implementation and interoperability for installations, environment, and civil works missions. SDSFIE is being managed by the Defense Installations Spatial Data Infrastructure (DISDI) Group. The DISDI Group is a formal governance group reporting to […]
