Hi Thomas The scale of the zoom levels depend on the type of map.
For raster maps the scale at zoom level 1 is the native scale of the file. For example 1m/pixel. Zoom level 2 will be 2m/pixel and 3 will be 3m/pixel. Overzoom 2 is 0.5m/pixel. For TMS maps it's the usual power by 2 scaling of the earth's size. An for WMS it's what ever is defined in the XML file. For vector maps, the scales are read from the table CMapTDB::scale_t CMapTDB::scales[] HTH Oliver > I'm new in the list and first I want to say hello. > > I want to know what is the basis of the zoom level.
