Does anyone know of an "almost always available" service URL for a public facing Web Map Tiling Service (WMTS)?
I'm keen to test WMTS client capabilities without having to configure a WMTS server.
Answer
Take a look at:
Those looking to test their web map applications against an Esri REST WMTS, please use USGS The National Map basemap services, which are published using ArcGIS Server 10.2:
http://basemap.nationalmap.gov/arcgis/rest/services
Click on any of the services in this directory and you will see a 'WMTS' link in the upper left corner which points towards the getcapabilities file for that service.
An example Tile request from the 'USGSShadedReliefonly' map service: http://basemap.nationalmap.gov/arcgis/rest/services/USGSShadedReliefOnly/MapServer/WMTS/tile/1.0.0/USGSShadedReliefOnly/default/default028mm/4/7/4.jpg
You can find a public APOLLO imagery WMTS available here. You can consider this an "always on" service
The service is compliant to the OGC Team engine test suite but note;
- The image tiles returned are generated on the fly with no server-side caching. The server is located in Atlanta, GA
- To improve performance of web clients, the server can be aliased against iws.erdas.com, iws2.erdas.com and iws3.erdas.com to workaround concurrency limits
- it does not implement some of the optional components such as the REST interface (KVP only) or feature info
- ESRI ArcGIS for Desktop 10.1 has a major bug in its WMTS client implementation that will mean no tiles will drawn with the service. This is a bug with ESRI and the way it issues KVP requests, specifically the format param
