How accurate are the data points?

The location will be determined in the course of the measurement with your device. The localisation is done depending on the capabilties and settings of the device

  • via GPS,
  • through the network (WLAN or mobile network) or
  • via the IP.

The localisation over GPS is most accurate. The localisation via mobile network provides only rough results, localisation via IP-address is often not very helpful.

Localisations with an accuracy of less than 2 km are not shown on the map, points with accuracy less than 10 km are not listed under the details. Therefore activating GPS (if available) is recommended. The accuracy of a specific measurement is available as open data (shown under details and via clicking on a pop-up in the map).
