Prototype: Austrian Elevation Service
The „Austrian Elevation Service“ is a prototype of a free and open elevation service basing on a Digital Elevation Model (DEM) with 10 Meter resolution. The service is basing on many textfiles with elevation data saved in EPSG: 3857 (Web Mercator).
The big advantage of this very simple approach is that every programming language can read textfiles. A database or a WMTS/WMS is not required.
The best way to test this prototype is a official Q-GIS-Plugin developed by Yasunori Kirimoto from Japan:
