OpenGIS Harmonization

Resolve use of org.opengis java package between OSGeo and OGC.

The OGC GeoAPI Implementation Specification requires exclusive use of the org.opengis Java package to establish common interfaces and classes for interoperability between Java projects (similar to SFSQL interoperability between databases).

OSGeo projects experimented in cross-project collaboration between GeoTools, OpenJUMP and degree projects made use of “geoapi-pending” interfaces defined in the org.opengis Java package.

This activity requires your participation and support:

Initiative outcomes:

  1. Refactor the use of org.opengis interfaces in the GeoTools project
  2. Rollback design changes made to GeoTools to facilitate adoption of GeoAPI interfaces
  3. Provide downstream projects with a migration script
