[MapProxy] Custom grid, bbox problems and no GETs

[Starck Heinrich]

Hello,

I still try to access to a public wmts offer
http://srv.doris.at/arcgis/rest/services/Basisdaten/FlaeWi/MapServer/WMTS/1.0.0/WMTSCapabilities.xml
In QGis I can access the WMTS offer.


In the WMTSCapabilities.xml I see different grid/bbox definitions:
1.
<ows:BoundingBox crs="urn:ogc:def:crs:EPSG::31255">
         EPSG:31255 - bounding box:  -115771.3204, 130037.7189, 115359.4571, 408002.5351
         (see http://spatialreference.org/ref/epsg/31255/)
2.
<ows:BoundingBox crs="urn:ogc:def:crs:EPSG::31255">
         <ows:LowerCorner>-4624770.696 -348480.1199000002</ows:LowerCorner>
         <ows:UpperCorner>403981.5399999991 123233.68599999989</ows:UpperCorner>
</ows:BoundingBox>
3.
<TileMatrix>
         <ows:Identifier>0</ows:Identifier>
         <ScaleDenominator>2267861.678580215</ScaleDenominator>
         <TopLeftCorner>5001000.0 -5622500.0</TopLeftCorner>
         <TileWidth>256</TileWidth>
         <TileHeight>256</TileHeight>
         <MatrixWidth>36</MatrixWidth>
         <MatrixHeight>60</MatrixHeight>
</TileMatrix>
...
<TileMatrixSet>default028mm</TileMatrixSet>
...
x2: 5001000.0 + 256*0.28/1000.0*2267861.678580215*36  (correct?) <--- Question 0
y2: -5622500.0 + 256*0.28/1000.0*2267861.678580215*60


I tried to build an empty grid to see the bounding box (QGis):
  test_grid_cache:
    grids: [doris_flaewi_wmts_test_grid]
    sources: []

  doris_flaewi_wmts_test_grid:
    srs: 'EPSG:31255'
    origin: 'nw'
    bbox: [-115771.3204, 130037.7189, 115359.4571, 408002.5351]

In QGis (with 'polygon from layer extent') I get a different polygon/box. Why?   <--- Question 1

I add the x/y-differences and justify the bbox.

But now there is no access to wmts - I see no 'GET' in mapproxy-util output.
util/httpd is running but no result, no timeout, only waiting.



I tried the 3 different bounding boxes (mentioned above) and I tried different coverages.
But there is no result, not a single GET.
BTW: I have other WMTS/WMS definitions they can access and deliver results.

I am no Python programmer. Therefore I don't know bbox for WMTS access is calculated.
Currently I think it should be the bbox I calculate from <TileMatrix> (3).
Is this correct?  <--- Question 2

After this I consider the question about the missing GETs.


Thank you,
Heinrich Starck
