[Thomas Konrad]

Hello Oliver,

thanks for your response! I got it working with the following configuration (it was indeed the grid which I had to change to GLOBAL_WEBMERCATOR):

The source is the ViennaGIS multi-porpose map (https://www.wien.gv.at/stadtplan/). The capabilities document is here: http://maps.wien.gv.at/wmts/1.0.0/WMTSCapabilities.xml. I followed the instructions at http://lists.osgeo.org/pipermail/mapproxy/2013-August/001674.html to calculate the right scale factors and generally followed http://mapproxy.org/docs/nightly/configuration_examples.html#create-wms-from-existing-tile-server for the basic configuration (by the way, I’m using the 1.7.0a nightly build).
