This OGC Testbed 20 Report defines a draft OGC Specification for Geographic High Efficiency Image Format (GeoHEIF). The Report specifies requirements and encoding rules for using the High Efficiency Image File Format (HEIF) for the exchange of georeferenced or geocoded imagery. The GeoHEIF specification defines HEIF properties to include the georeference information in one or more image items. In addition, other HEIF properties are added to define the semantics of dimensions and cell properties that together allow for converting HEIF into a datacube container.

Please note that while the intent is to submit this document to the OGC for consideration as an OGC Standard, this document is internally referred to as an OGC Testbed 20 Report or more simply “this Report” or “this specification”.
