Tile Map Service or TMS, is a specification for tiled web maps, developed by the Open Source Geospatial Foundation. The definition generally requires a URI structure which attempts to fulfill REST principles. The TMS protocol fills a gap between the very simple standard used by OpenStreetMap and the complexity of the Web Map Service standard, providing simple urls to tiles while also supporting alternate spatial referencing system.
