GeoAPI represents a free software solution providing Java interfaces tailored for GIS applications, created under the auspices of the Open Geospatial Consortium. It adheres to international protocols from the ISO 19100 series alongside OGC standards, customizing them to fit Java's specific requirements. The principal standards incorporated include:
- ISO/TS 19103:2005 — Conceptual schema language
- ISO 19115:2003 — Metadata
- ISO 19115-2:2009 — Metadata extensions for imagery and gridded data
- ISO 19111:2007 — Spatial referencing by coordinates
Recognized as an official OGC standard, GeoAPI 3.0 is published as an implementation specification. Its Java Archive (JAR) files can be accessed through the Apache Maven central repository. The interfaces are organized within the org.opengis package hierarchy.
History
The first public distribution of Java interfaces under the org.opengis namespace took place on January 12, 2001, within the OpenGIS Coordinate Transformation Service Implementation Specification, later designated as GeoAPI 1.0.
In response to a 2002 initiative seeking a geospatial API, the OGC established the GeoAPI Standard Working Group and launched GeoAPI 2.0 in June 2005. After a period of inactivity, the group reconvened in 2009 and subsequently released GeoAPI 3.0 in 2011, with further revisions issued in 2017 (version 3.0.1) and 2023 (version 3.0.2).
The GeoTools project participated in developing GeoAPI 2 but diverged by forking the interfaces before the release of GeoAPI 3, maintaining the org.opengis namespace. This led to incompatibilities with later OGC versions, a situation remedied with the release of GeoTools version 30 in October 2023.
