Latest published version 2.0 of the OGC Two Dimensional Tile Matrix Set and Tileset Metadata standard: HTML PDF
Latest release notes: HTML PDF
This standard defines the models and encodings for the Tile Matrix Sets and Tileset metadata of OGC API - Tiles.
Before becoming an independent OGC standard, the original concepts were used in the OGC Web Map Tile Service (WMTS) and OGC GeoPackage.
The main new capabilities of this independent standard are:
- the concept of common Tile Matrix Sets that can be registered e.g., in the OGC Tile Matrix Set Register, re-used and easily recognized by URI,
- support for variable width tile matrices to better accommodate polar regions of Tile Matrix Sets defined in a geographic CRS,
- a new service-independent tileset metadata model and encodings, including the ability to describe schemas for component data layers of tiles of vector features or coverage data,
- a JSON encoding of Tile Matrix Set definitions.
This GitHub repository contains the draft content for a future revision or corrigendum of the standard.
The repo is organized as follows:
- registry/ - The authoritative source of the OGC Tile Matrix Set Register, maintained by the OGC API - Tiles Standard Working Group
- release_notes/ - the differences and improvements between versions 2.0 (OGC 17-083r4) and 1.0 (OGC 17-083r2)
- schemas/ - XML and JSON Schemas and examples for TileMatrixSet definitions and Tileset Metadata
- standard/ - the main standard document content
- standard/uml/ - The UML models used in the standard in EAP format.
