I am using MapProxy to serve an MBTiles file (treated as a cache only source) as a WMTS. The getCapabilities response from such a WMTS has a BBox -180/-85 to 180/85. However, I know that the tiles in the set are much more localised and
wish to impose a BBox ans min/max scale on the layer. Unfortunately there appears to be no way to apply a BBox to a
cache (only to a source – which this scenario doesn’t have because the whole tile set is served from the MBTiles file as if it were a cache).
Is it possible to impose a BBox on a cache, and if not, is it possible to otherwise correct the GetCapabilities response?
