The membership of the Open Geospatial Consortium (OGC) has approved version 1.1 of the GeoTIFF Encoding Standard.
The GeoTIFF format was initially developed during the early 1990’s (N. Ritter & Ruth, 1997) while Ritter was working at NASA Jet Propulsion Library. The objective was to leverage a mature platform independent file format (TIFF) by embedding georeferencing metadata to mage data.
Until recently, there has been no up-to-date specification for the GeoTIFF file format. The version version 1.1 of the OGC GeoTIFF Standard published September, 2019 will be backwards-compatible with the original GeoTIFF 1.0 specification of 1995.
This new OGC Standard, Geographic Tagged Image File Format (GeoTIFF) basically specifies requirements and encoding rules for using the Tagged Image File Format (TIFF) for the exchange of georeferenced or geocoded imagery. The OGC GeoTIFF 1.1 standard formalizes the existing community GeoTIFF specification version 1.0 and aligns it with the continuing addition of data to the EPSG Geodetic Parameter Dataset.
“GeoTIFF 1.1, as an international standard, allows the DGIWG GeoTIFF profile to rely on a standardized GeoTIFF standard inline with the modern EPSG register for the production of its elevation data, orthoimages, and raster maps products, or for such production by DGIWG nations. IGN and, more generally in Europe, all mapping agencies may now rely on a modernized and maintained specification for their raster or gridded products, such as the INSPIRE Orthoimagery and Elevation data specifications.” Emmanuel Devys, IGN and DGIWG Imagery and Gridded Data Technical Panel lead.

What are OGC Standards
OGC(R) standards are technical documents that detail interfaces or encodings. Software developers use these documents to build open interfaces and encodings into their products and services. These standards are the main “products” of the Open Geospatial Consortium and have been developed by the membership to address specific interoperability challenges.
Example are the OGC Web Services (OWS) which are OGC standards created for use in World Wide Web applications i.e. OWS,WMS,WFS, WMTS among a host of them. See more here

The Open Geospatial Consortium (OGC) is an international consortium of more than 530 businesses, government agencies, research organizations, and universities driven to make geospatial (location) information and services FAIR – Findable, Accessible, Interoperable, and Reusable.
OGC’s member-driven consensus process creates royalty free, publicly available geospatial standards. Existing at the cutting edge, OGC actively analyzes and anticipates emerging tech trends, and runs an agile, collaborative Research and Development (R&D) lab that builds and tests innovative prototype solutions to members’ use cases.
OGC members together form a global forum of experts and communities that use location to connect people with technology and improve decision-making at all levels.
