) in its 19100 series of documents and the Open Geospatial Consortium ( OGC) in its abstract and implementation specifications. GeoAPI provides an interpretation and adaptation of these standards to match the constraints and usages of the target programming language. The international standards translated to Java interfaces are: * ISO/TS 19103:2005 — Conceptual schema language * ISO 19115:2003 — Metadata * ISO 19115-2:2009 — Metadata — Part 2: Extensions for imagery and gridded data * ISO 19111:2007 — Spatial referencing by coordinates GeoAPI 3.0 has been approved as an OGC standard and is published as an OGC implementation specification.GeoAPI specification

History

The first public release of Java interfaces in org.opengis packages was in the OpenGIS Coordinate Transformation Service Implementation Specification standard, published on January 12, 2001.OpenGIS Coordinate Transformation Service Implementation Specification

/ref> Developers of Open Source projects joined later, following a public email calling for the creation of a geospatial API in October 2002.Call for the creation of a geospatial API
/ref> OGC created a GeoAPI Standard Working Group and published GeoAPI 2.0 in June 2005.
