WMTS Calypso advertises incompatible tile matrix set for Costa Rica data #9

Open robinhoutmeyers opened 6 years ago

robinhoutmeyers commented 6 years ago

One of the advertised tile matrix sets in the WMTS Calypso capabilities is defined in EPSG:5042. This is a UPS South reference of which the projection bounds do not overlap with the data bounds (Costa Rica area). As such, the tile matrix set cannot be used to access the data.

No sure what is the issue here. The EPSG:5042 tile matrix is not correctly defined (it passed the validation tests) ?

When you look at the WMTS capabilities at http://cloudsdi.geo-solutions.it/geoserver/geoedge/gwc/service/wmts?SERVICE=wmts&REQUEST=getcapabilities&VERSION=1.0.0, the geoedge-sentinel2-tci-costarica layer links to various TileMatrixSetLinks, including one for EPSG:5042. The latter is however not applicable for the offered data, because Costa Rica lies outside the bounding box of the EPSG:5042 projection (see https://epsg.io/5042). This is not tested by any compliancy test. Thus, ideally this TileMatrixSetLink should be removed as clients will not be able to request the data in that tiling scheme.

Ah! Yes you are correct ... my apologies I misunderstood the issue. I just disassociated that layer with 5042:

It should be good now.

Great, thanks! Just to clarify, we were able to successfully connect with the service and retrieve the data (by using another linked gridset); we logged this for completeness.
