Spezifikationen
Weblinks:
XYZ
Google Maps API / Bing SDK / OpenStreetMap API.
Achtung: Es gibt inkompatible Tiling-Spezifikationen, bzw. Implementationen: "Google Maps, Microsoft Bing/Virtual Earth, Yahoo Maps, and other commercial API providers as well as OpenStreetMap and OpenAerialMap are using the same projection and tiling profile and tiles are therefore compatible. The extents of all tiles as well as the zoom levels (resolution in meters per pixel) are predefined for the whole earth. Difference is only in the way how the equivalent tiles are indexed. There are three main systems of tile adressing: Google XYZ, Microsoft QuadTree and from the open-source world comming TMS (Tile Map Service). (Source: [3]; siehe dazu auch [4].
WMTS
