GeoPackage Elevation Extension Interoperability Experiment

For more information please contact innovation@ogc.org

This interoperability experiment (GPKG-EE IE) tested a proposed extension to the OGC GeoPackage Encoding Standard (12-128r1). Testing was achieved by building GeoPackages using the proposed extension and then using those GeoPackages in visualization and analysis software. This IE produced an OGC Engineering Report that discusses whether the elevation extension meets community requirements and can proceed to the OGC standards adoption process. The OGC GeoPackage Elevation Extension Interoperability Experiment Engineering Report is now available.

The revised Interoperability Experiment Activity Plan can be downloaded from:

The Activity plan was regularily updated to reflect consensus decisions of the group.

An elevation extension is required to store tiled gridded elevation data in a GeoPackage to support a variety of visualization and analysis operations. The proposed extension is based on work documented in the OGC Discussion Paper, “Envisioning an Elevation Extension to the GeoPackage Encoding Standard” (OGC 15-039) and subsequent work performed by the GeoPackage Standards Working Group. The SWG proposes to leverage the existing GeoPackage structure for raster tiles using PNG or TIFF files as the container for the elevation values themselves.
