NGDA Overview

In November 2010, the Office of Management and Budget (OMB) released the OMB Circular A-16 Supplemental Guidance. Its primary focus was on geospatial data as a capital asset and providing the foundation for a portfolio management approach to a National Geospatial Data Asset (NGDA) Portfolio. The portfolio consists of National Geospatial Data Asset Themes (NGDA Themes) and their associated National Geospatial Data Asset Datasets (NGDA Datasets).

An NGDA Dataset is an asset that has been designated as such by the Federal Geographic Data Committee (FGDC) Steering Committee and meets at least one of the following criteria:

  • Used by multiple agencies or with agency partners such as State, Tribal and local government
  • Applied to achieve Presidential priorities as expressed by OMB

  • Expressly required by statutory mandate.

    decisions, redistribution of resources, management of issues and mitigation of risks to the


The National Geospatial Data Asset (NGDA) Portfolio Community provides information related to the NGDA Portfolio, NGDA Portfolio Management, NGDA Themes, and NGDA Lifecycle Maturity Assessments. The NGDA Portfolio is based on the goals, objectives, and actions outlined in OMB Circular A-16 Supplemental Guidance and the National Spatial Data Infrastructure (NSDI) Framework.

The NGDA Portfolio Community contains temporal reports for NGDA, NGDA Themes, NGDA Lifecycle Maturity Assessments, NGDA Roles and Responsibilities, and various other NGDA Portfolio reports.
