[MapProxy] Custom grid, bbox problems and no GETs

[Oliver Tonnhofer]

Hi,

you need to use a bounding box that matches with the TopLeftCorner.
Your calculation (question 0) looks right, but you might need to switch x and y.


Q1: Additional buffers? It might use the LatLongBoundingBox?

You should remove all coverages, if the bbox is right and if you are still not seeing any requests.


Regards,
Oliver
