From Earth Observation to Government Decisions: An Evidence-Based UN-IGIF Assessment Framework Applied to Rwanda Space Agency’s GeoHub

National geospatial infrastructures increasingly connect Earth Observation (EO), geospatial artificial intelligence (GeoAI), interoperable services, and public-sector decision processes. However, an explicit method for assessing whether these technical functions operationalize the nine pathways of the United Nations Integrated Geospatial Information Framework (UN-IGIF) remains underdeveloped. This Communication develops a pathway-to-function-to-evidence assessment framework and applies it illustratively to the Rwanda Space Agency (RSA) GeoHub case. Using the UN-IGIF pathway definitions as normative criteria and the available GeoHub description as case material, we classify reported functions, map their institutional and technical dependencies, and identify the records required to substantiate operational performance and decision uptake. Worked mappings cover EO data stewardship, GeoAI processing, interoperable delivery, and sectoral decision workflows. The contribution is a transparent analytical procedure that distinguishes reported capabilities, proposed applications, and independently verified outcomes; it does not constitute an audit or quantitative impact evaluation. The framework offers a transferable basis for planning and evaluating EO-enabled geospatial infrastructures in emerging space ecosystems.
