Two benches on top of the Katrin mountain hill top near Bad Ischl, Salzkammergut, Austria. From the top, visitors can spot seven lakes in the valleys below, each indicated by a bench. The names are applied by a router using some form of Isonorm, adesign for technical lettering as issued in 1980 by the International Standard Organisation (ISO). A detail of some of Isonorm’s characters, plus instructions for drawing and application can be found in this pdf (1997).
Most likely, Isonorm as installed in the router software was used for these benches, but Isonorm comes in various digital versions.
