The customer learned the Webmercator fix which was deployed on May 31st 2023 had the goal to convert the Capabilities/Contents/Layer/TileMatrixSetLink/TileMatrixSet information to the latitude of Switzerland. This was necessary so that the GetCapabilities document does not publish zoom levels that cannot be provided in the backend service (service-wmts), because the resolution of the data of the corresponding layer does not allow this.
When implementing this adjustment, the list of available TileMatrixSet have not been adjusted correctly. This caused inconsistency in the GetCap between:
Capabilities/Contents/Layer/TileMatrixSetLink/TileMatrixSet
Capabilities/Contents/TileMatrixSet
There were layers where the set specified in Capabilities/Contents/Layer/TileMatrixSetLink/TileMatrixSet could not be found in Capabilities/Contents/TileMatrixSet. This caused a parsing error for certain clients.
With the fix of 07/04/2023 all TileMatrixSet specifications in the document:
Capabilities/Contents/Layer/TileMatrixSetLink/TileMatrixSet
Capabilities/Contents/TileMatrixSet
can be referenced.
