USAF SDSFIE Data Models and Guidance


GeoBase is the Air Force Installation Geospatial Information and Services (IGI&S) program for geospatial information and was established to support the installation & environmental geospatial assets. The vision of the GeoBase program is to provide precise and reliable geospatial data that supports interoperability across the Air Force. The current Air Force 3.1 Adaptation Data Model (GeoBase 3.1) maintains an IGI&S data standard that supports the Air Force mission by providing flexibility within the program while remaining aligned with the SDSFIE 3.1 Gold model. All USAF commands and installations must implement the latest Data Model (GeoBase 3.1) to enhance capabilities in all related systems.

GeoBase 3.1 Data Model and accompanying documentation were released February 27, 2015.


Beginning in late 2013, several Tiger Teams met to standardize the AF Adaptation. The Tiger Teams met to focus on many specific aspects of the Adaptation and developed permanent standards and rules that were reflected in the 3.1 release. The Tiger Teams consisted of DWG members, SME’s, those with specific skills, experience in past migrations, or working knowledge. Each month in 2014, the Data Working Group had been kept informed of the progress of each Team. The collective purpose of these Teams was to standardize the logical and physical models for the data to be used seamlessly in related systems.

The utility and environmental models within the GeoBase 3.1 Data Model were developed by the direction and recommendations of Subject Matter Experts (SMEs). The SMEs defined the technical requirements for creating the geospatial data model to meet enterprise-wide business requirements. Other data elements, such as domain values and attributes for specific feature classes, were reviewed and improved per SME comments and suggestions. The requirement-collection effort included many people in and outside of the GeoBase program and spanned over one year.

Official AF Adaptation Documentation
Released February 27, 2015

Alongside the GeoBase 3.1 Data Model are documents that define standards to ensure geospatial data integrity. GeoBase documentation is designed to function at an acceptable level of quality for use by the Air Force Community related to the GeoBase program. Each document included in the 3.1 Adaptation Release Package have been developed specifically to define all elements in the Adaptation geodatabase.

Current Status

The current Air Force Data Model is GeoBase 3.1, which was released on February 27, 2015. Air Force GeoBase is working with DISDI Working Groups to start preliminary design on the future post-GeoBase 3.1 model.
