Hi all, Piero is right - what I said applies to the case that grid and CRS axes align - which addresses the vast marjotiy of cases in my experience. However, OGC coverages (to some extent CIS 1.0, more with CIS 1.1) can also address more complex cases (irregular grids, grids embedded in higher-dim

Hi all, why not simply check against the compliance tests of WCS 2 and maybe a reference implementation? Might be the easiest for answering all such questions. cheers, Peter On 04/10/2017 04:23 PM, Even Rouault wrote: > > On lundi 10 avril 2017 15:57:03 CEST Andrea Aime wrote: > > > Hi Even, >

Hi Even, in CIS 1.1 they state: Coverages are assumed to have a 1:1 correlation between the axis names given in axis-Labels and gridLabels, i.e.: they shall relate pairwise, given by their sequence position. For example, axisLabels=“Lat Long h date” and gridLabels={i j k l} implies a correspondenc
