| 43 | * There are two ready-made MapAdapters: |
||
| 44 | * - TileMapAdapter, which is ready to use for OpenStreetMap or Google (Mercator projection) |
||
| 45 | * - WMSMapAdapter, which could be used for the most WMS-Server (some servers show errors, because of image ratio) |
||
| 46 | * |
||
| 47 | * MapAdapters are also needed to form the HTTP-Queries to load the map tiles. |
||
| 48 | * The maps from WMS Servers are also divided into tiles, because those can be better cached. |
