Hi, Consider the following WMTS server: *https://geoservices-urbis.irisnet.be/geoserver/gwc/service/wmts <https://geoservices-urbis.irisnet.be/geoserver/gwc/service/wmts>*
One of the subdataset path generated by GDAL is *WMTS:https://geoservices-urbis.irisnet.be/geoserver/gwc/service/wmts?SERVICE=WMTS&REQUEST=GetCapabilities&VERSION=1.0.0,layer=Ortho,tilematrixset=EPSG:4326 <https://geoservices-urbis.irisnet.be/geoserver/gwc/service/wmts?SERVICE=WMTS&REQUEST=GetCapabilities&VERSION=1.0.0,layer=Ortho,tilematrixset=EPSG:4326>* When I try to download a map I notice URL issue/error. *gdalinfo "WMTS:https://geoservices-urbis.irisnet.be/geoserver/gwc/service/wmts?SERVICE=WMTS&REQUEST=GetCapabilities&VERSION=1.0.0,layer=Ortho,tilematrixset=EPSG:4326 <https://geoservices-urbis.irisnet.be/geoserver/gwc/service/wmts?SERVICE=WMTS&REQUEST=GetCapabilities&VERSION=1.0.0,layer=Ortho,tilematrixset=EPSG:4326>" tile.png --debug on --config GDAL_ENABLE_WMS_CACHE NO* from debug: *HTTP: Requesting [1/4] https://geoservices-urbis.irisnet.be/geowebcache/service/wmts/rest/Ortho <https://geoservices-urbis.irisnet.be/geowebcache/service/wmts/rest/Ortho>//EPSG:4326/EPSG:4326:7/27/129?format=image/jpeg* look at the double slash (//) chars in the above URL When you go to service Capabilities you can find the following resource URL: * <ResourceURL format="image/jpeg" resourceType="tile" template="https://geoservices-urbis.irisnet.be/geowebcache/service/wmts/rest/urbisNL/ <https://geoservices-urbis.irisnet.be/geowebcache/service/wmts/rest/urbisNL/>{style}/{TileMatrixSet}/{TileMatrix}/{TileRow}/{TileCol}?format=image/jpeg"/>* but in the layer definition *Style* tag is empty: *<Style isDefault="true"><ows:Identifier/></Style>* This is probably the reason that GDAL make path using an empty string and this generate double slash chars. If you remove redundant slash the server responses and returns a tile, the example: *https://geoservices-urbis.irisnet.be/geowebcache/service/wmts/rest/Ortho/EPSG:4326/EPSG:4326:14/3567/16784?format=image/jpeg <https://geoservices-urbis.irisnet.be/geowebcache/service/wmts/rest/Ortho/EPSG:4326/EPSG:4326:14/3567/16784?format=image/jpeg>* And the question is: is this service or GDAL bug? :-) Wouldn't it be a good idea for GDAL to check the URL path for correctness before sending the request?
