+### Tournament is not shown with the correct location on the map
+
+This is a known issue. The location of the tournament is not always correct. This is due to the fact that the [OSM](https://www.openstreetmap.de) is not always capable of performing the geocoding right. There are two potential outcomes:
+
+  1. Tournament location falls back to the default address of the corresponding tennis federation. There will then be a list of tournaments associated to the default address.
+     * <img width="20%" src="images/geocoordsNotFound.png">
+  2. Tournament location is showing a completely different location. In this case please click on the link next to "Adresse". This will then lead you to the address on [Google Maps](http://maps.google.com) and this location is mostly correct.
