[gdal-dev] WMTS generating GET URL problem

[Michał Kowalczuk]

Sorry for the mistake in the last email. Instead of pasting *gfdalinfo *command
i should paste this:
*gdal_translate -srcwin 0 0 12235811 6137602 -outsize 512 512
"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*
