Using the EPSG:2193 projection from WMTS capabilities for a layer: https://data.linz.govt.nz/services;key=60c2f93ec4dc45448ff7d93df524eb75/wmts/1.0.0/layer/50767/WMTSCapabilities.xml
I'm trying to produce a JSON layer definition for use in MapFish Print requests.
I can get other WMTS layers to work, but this one is eluding me. I'm wondering if the XML provided by the service is actually correct as it states that each TileMatrix has a:
<TopLeftCorner>10000000.0 -1000000.0</TopLeftCorner>
But the bounding box provided would suggest a different TopLeftCorner?
<ows:BoundingBox crs="urn:ogc:def:crs:EPSG::2193">
<ows:LowerCorner>3087000.000000 274000.000000</ows:LowerCorner>
<ows:UpperCorner>7173000.000000 3327000.000000</ows:UpperCorner>
</ows:BoundingBox>
I've tried updating TopLeftCorner based on these values, but I'm still not seeing any tiles come through on my maps.
I can pull the WMTS layer into QGIS without issue. Perhaps there's a way I can export the JSON I need from QGIS itself? Looking at the Layer Properties, QGIS also reports a 10000000.0 -1000000.0 top left though.
The layer JSON I've manually created from the XML capabilities, which doesn't work, is as follows. Can anyone see anything I might be getting wrong?
