[MapProxy] WMTS MatrixWidth at Level 0

[Oliver Tonnhofer]

Hi,

you need to convert the WMTS TileMatrixSet to a MapProxy grid. 
There is no script for that but you’ll find some guidance in this mail: http://lists.osgeo.org/pipermail/mapproxy/2013-August/001674.html

You can use mapproxy-util grids (http://mapproxy.org/docs/nightly/mapproxy_util.html#grids) to show you the final grid (MatrixWidth and MatrixHeight of each level).

Please let us know if it works and how the final grid looks like.

Regards,
Oliver
