Hi Peter, Not sure if I understood correctly. If a srsName would be provided for the <gml:DomainSet> in CIS 1.0 and if it should not be http://www.opengis.net/def/crs/OGC/0/Index2D, than should be the same as in the gml:Envelope,... view reply

just briefly, need to leave: sequence rule is just about linearization in a file, so low-level storage parameter. Has nothing to do with the high-level axis sequence definition. Sequencerule would take whatever axis sequence is given and then,... view reply

Hi Iurie, I do not have time to dive through the INSPIRE documentation, but from what you say some examples seem to be plainly wrong: using a uom different than defined in the CRS cannot work. I like your coloring which shows nicely how axis... view reply

I try to conclude from what I understood, supposing that a Geotiff image in EPSG:3035 with one band looks like in the next picture (37258 pixels along West - East axis and 29841 pixels along North - South axis): Than the response from a... view reply

Hi Peter, I almost clarified and I will try to conclude. Just I need a small clarification. You mentioned that: <<as per CIS 1.0 it is not mandatory to have srsName mentioned in the domainSet. In case it is missing, the value from... view reply

Hi, In a separate tread https://themes.jrc.ec.europa.eu/discussion/view/207594/habitatsandbiotopes-in-wcs we arrived to the conclusion that with current XSD schemas, a WCS is not able serve any INSPIRE data theme that has a rectified grid... view reply

But in example 19 and 20 the GetCoverage requests uses the CoverageID=Glasgow_bron_b which seems to indicate that the respond will be coverage-data for a sub-area (Glasgow). In this example (Glasgow_bron_b) is a full coverage, not a subset, it... view reply

re axisLabels in your earlier question: as per CIS 1.0 it is not mandatory to have srsName mentioned in the domainSet. In case it is missing, the value from Envelope will be taken (loosely speaking, "inherited"). -Peter PS: if you... view reply

I cannot check in detail, but it might well be that the INSPIRE example is plainly wrong (as per OGC CIS 1.x and ISO 19123-2). INSPIRE has deviated from OGC and ISO coverage model, maybe that is the reason. FYI, currently efforts are under way to... view reply

Hi Peter, I see an issue with the declaration of the srsName="http://www.opengis.net/def/crs/EPSG/0/3035" in the gmd:domainSet, because neither of the values provided in the GridEnvelope element are in EPSG 3035, but are the... view reply

Hi Iurie, I cannot check all the coverage, marked parts look good except for the axis swap. sequenceRule is just about storage linearization (row major vs column major), not related to the logical level like axis sequence. Hence, axes must remain... view reply

Thank you Peter, indeed it really helps. This difference between CIS 1.1 and GMLCOV/CIS 1.0 is really important. Currently the INSPIRE Application Schema for Elevation points to GMLCOV 1.0 and not to CIS 1.1, so I am not sure if Member... view reply

- as per CIS 1.0: axis labels must be axisAbbrev items in CRS definition, as per OGC resolver (cf. URL of CRS), in this case: "Y X". - as per CIS 1.1 (due to an intervention by the ISO 19111 group): axis labels must agree with CRS axes... view reply
