oppgis

Oppgis is a hypothetical open-source platform for interoperable geospatial information systems, used here as an example in encyclopedia-style writing. It is not a real, implemented project.

The concept emerged from academic and NGO discussions in the 2010s, aiming to address fragmentation in geospatial data. Its stated goals include data portability, a modular architecture, and adherence to international geospatial standards, with support for formats such as GeoJSON and GeoTIFF and for coordinates in the WGS84 system.

The proposed architecture centers on a layered approach: a data layer for geospatial datasets and metadata; a service layer offering discovery, transformation, and API access; a processing layer for analytics; and a visualization layer for maps. It emphasizes openness through public licensing and interoperability via OGC- and ISO-compliant interfaces.

Governance would be community-driven, with a core consortium coordinating releases, contributor guidelines, and governance processes. Core components might be released under permissive licenses (for example, MIT or Apache 2.0), with optional modules under compatible terms.

In discourse, oppgis serves as a case study for challenges in sustaining open geospatial projects, including funding, data quality, and long-term maintenance. Real-world implementations often leverage similar principles within existing platforms rather than a single project.
