Tile Matrix Sets
Custom tiling schemes, in addition to the predefined ones, follow the OGC Two Dimensional Tile Matrix Set and Tile Set Metadata 2.0 Standard. They are used by the building blocks Tile Matrix Sets and Tiles and by tile providers.
The JSON representations of the predefined tiling schemes are available on GitHub and can serve as templates.
Storage
Tiling schemes reside in the Store as values with type tile-matrix-sets and relative path {tileMatrixSetId}.json.
