Because of increasing security problems of Java applets, their replacement had to be advanced: A new map viewer based on JavaScript and OpenLayers 2 was launched.

Following the original development schedule, a viewer based on OpenLayers 3 replaced it in 2015.

The site search was improved: The results of an own (complete and up-to-date) database search and of a Google site search, which is more input-tolerant, are listed.
