GeoServer producing transparent images for cascaded WMTS service when reprojected
Geographic Information Systems Asked on February 20, 2021
I’m cascading a WMTS service through GeoServer so I can consume it as a WMS service. This part now works with the below urls thanks to a very recent bug fix. I’m now attempting to reproject the coordinate system in order to allow WMS service calls using the localized coordinate system. Unfortunately all WMS calls using the reprojected SRS result in transparent images being served up rather than the expected imagery.
Any ideas of any steps I might be missing, problems with the WMS urls I’m constructing, or whether this might be due to a bug in GeoServer?
I’m consuming the following NZ Topo50 Maps service using the following WMTS capabilities endpoint:
Then I’m reprojecting the layer using the following settings:
An example WMS request I’m attempting to make using a bbox of 1221300,4965200,1293300,5037200 in the native EPSG:2193 coordinates:
- http://localhost:8080/geoserver/wms?service=WMS&version=1.1.1&request=GetMap&layers=gavin%3Anztopo50&bbox=1221300%2C4965200%2C1293300%2C5037200&srs=EPSG%3A2193&width=500&height=500&format=image%2Fpng
This is the area of imagery I’m expecting to see instead of the transparent image:
Workaround attempt…
Based on the feedback from Ian Turton I decided to try a work-around where I took the original WMTS capabilities XML served up by LINZ, stripped out the EPSG:3857 capabilities, then hosted the modified XML myself to register with GeoServer.
All looked promising, with GeoServer defaulting to EPSG:2193. However all requests made for imagery resulted in the following error being returned:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>

<ows:Abstract>The Topo50 map series provides topographic mapping for the New Zealand mainland, the Chatham Islands, and offshore islands at 1:50,000 scale.
Along with the paper-based Topo50 map series, digital images of the maps are also publicly available.
Georeferenced raster digital images are provided at a resolution of 300 DPI. Georeferencing allows adjacent maps to be accurately and automatically aligned within GIS systems.
For more information, and a description of the georeferencing keys:
http://www.linz.govt.nz/topography/topo-maps/topo50/digital-images
Please be aware of the following:
- Representation of a road or track does not necessarily indicate public right of access. For access rights, maps and other information, contact the New Zealand Walking Access Commission - www.walkingaccess.govt.nz
- The Department of Conservation and other agencies should be contacted for the latest information on tracks and back country huts. Closed tracks are defined as being no longer maintained or passable and should not be used.
- Not all aerial wires, cableways and obstructions that could be hazardous to aircraft are held in the data.
- Contours and spot elevations in forest and snow areas may be less accurate.
- Not all pipelines including both underground and above ground are held in the data or shown on the printed maps. For the latest information please contact the utility and infrastructure agencies
- Permits may be required to visit some sensitive and special islands and areas. Contact the Department of Conservation to see if you need to apply for a permit.</ows:Abstract>

I don't think that will work (as you have seen) - The project handling code in the WMTS (and WMS) cascading code is fairly rudimentary as it just picks the first one it recognises as valid, when it should really populate the Native Projections pull down with all the possible choices provided by the remote host.
I think the only current way to do what you want at present is to leave the native and declared SRS as they are and just request your WMS map in the projection you want (EPSG:2193) GeoServer will then either reproject to that or if it is smart request the correct tiles directly without reprojecting (I'd have to check the code but I don't recall it being that smart).
One thing to try is setting Force Declared rather than Reproject to Declared as that might force it to request the correct tiles.
It would be worth raising a bug report that declaring a supported CRS doesn't work, and may be an enhancement request to look at the whole WMS and WMTS projections issue (but with out sponsorship that is unlikely to get fixed soon).
