CDB Vector Data in GeoPackage Interoperability Experiment

For more information please contact


The CDB Vector Data in GeoPackage Interoperability Experiment  has tested encodings of vector data via GeoPackage in the OGC CDB 1.1 Standard and Best Practices. A primary objective of this IE was to inform decision making for possible enhancements in the OGC CDB Standards Working Group (SWG). 


The proposed IE outcomes resulted in recommendations for changes to, alternatives to, or replacement of, the OGC CDB 1.1 Volume 1:  Core Standard (15-113r5) and OGC CDB 1.1 Volume 4: OGC CDB Best Practice use of Shapefiles for Vector Data Storage (16-070r3).  The proposed IE outcomes further resulted in recommendations for future work in the next major revision to the OGC CDB Standard and Best Practices (CDB 2.0).



Participants in this IE analyzed and/or perform one or more of the following experiments, and contribute to the IE Engineering Report.  Two ‘sample’ CDB datasets were in the process of being approved for release as resources to participants in this IE.
