3 November 2015. The Open Geospatial Consortium (OGC) announces a Call for Participation (CFP) in the OGC GeoPackage (GPKG) Elevation Extension Interoperability Experiment (GPKG-EE IE).
The OGC GeoPackage Standards Working Group (SWG) has identified a need to store tiled gridded elevation data in a GeoPackage. GeoPackage is an open, standards-based, platform-independent, portable, self-describing, compact format for transferring geospatial information. The SWG has developed a candidate extension to the GeoPackage Encoding Standard to support elevation data.
