| * There are two ready-made MapAdapters: |
| * - TileMapAdapter, which is ready to use for OpenStreetMap or Google (Mercator projection) |
| * - WMSMapAdapter, which could be used for the most WMS-Server (some servers show errors, because of image ratio) |
| * |
| * MapAdapters are also needed to form the HTTP-Queries to load the map tiles. |
| * The maps from WMS Servers are also divided into tiles, because those can be better cached. |
