Hi, I found that DescribeCoverage is also defining gml:coverageFunction
<gml:coverageFunction> <gml:GridFunction> <gml:sequenceRule axisOrder="+2 +1">Linear</gml:sequenceRule> <gml:startPoint>0 0</gml:startPoint> </gml:GridFunction> </gml:coverageFunction> I do not understand the meaning of "+2 +1" here. Does it mean that for that coverage the second number of the coordinate pair should be picked before the first one? In that case the nurc__Pk50095 (EPSG:32633) would be OK and lead to Easting-Northing. The same axisOrder="+2 +1" is used also for nurc_mosaic (EPSG:4326) and that would lead to Long-Lat. Is that the correct end result? -Jukka Rahkonen- Lähettäjä: Rahkonen Jukka (MML) [mailto:[email protected]] Lähetetty: 6. elokuuta 2015 13:18 Vastaanottaja: [email protected] Aihe: [Geoserver-users] BoundingBox axis troubles with WCS 2.0.1 Hi, I am not sure if I understand it right but I feel that some bounding boxes in the WCS 2.0.1 GetCapabilities and DescribeCoverage are wrong. They are optional in the CoverageSummary but Geoserver delivers them. This is about nurc__mosaic coverage from GetCapabilities <wcs:CoverageSummary> <wcs:CoverageId>nurc__mosaic</wcs:CoverageId> <wcs:CoverageSubtype>RectifiedGridCoverage</wcs:CoverageSubtype> <ows:WGS84BoundingBox> <ows:LowerCorner>6.346 36.492</ows:LowerCorner> <ows:UpperCorner>20.83 46.591</ows:UpperCorner> </ows:WGS84BoundingBox> <ows:BoundingBox crs="http://www.opengis.net/def/crs/EPSG/0/EPSG:4326";> <ows:LowerCorner>6.346 36.492</ows:LowerCorner> <ows:UpperCorner>20.83 46.591</ows:UpperCorner> </ows:BoundingBox> </wcs:CoverageSummary> The WCS 2.0.1 Core standard defines WGS84BoundingBox and BoundingBox this way: wgs84-BoundingBox: Minimum bounding rectangle surrounding dataset, using WGS 84 CRS with decimal degrees and longitude before latitude boundingBox: Minimum bounding rectangle surrounding dataset, in available CRS Thus in the nurc__mosaic case the WGS84BoundingBox is correct but BoundingBox should have axis flipped to suit with http://www.opengis.net/def/crs/EPSG/0/EPSG:4326 <ows:LowerCorner>36.492 6.346</ows:LowerCorner> <ows:UpperCorner>46.591 20.83</ows:UpperCorner> CoverageSummary has both bounding boxes right for the nurc__Pk50095 coverage which is in EPSG:32633. However, in DescribeCoverage the axis order is different and for my mind wrong: GetCapabilities: <ows:BoundingBox crs="http://www.opengis.net/def/crs/EPSG/0/EPSG:32633";> <ows:LowerCorner>347649.93086859107 5176214.082539256</ows:LowerCorner> <ows:UpperCorner>370725.976428591 5196961.352859256</ows:UpperCorner> </ows:BoundingBox> DescribeCoverage: <gml:boundedBy> <gml:Envelope srsName="http://www.opengis.net/def/crs/EPSG/0/32633"; axisLabels="E N" uomLabels="m m" srsDimension="2"> <gml:lowerCorner>5176214.082539256 347649.93086859107</gml:lowerCorner> <gml:upperCorner>5196961.352859256 370725.976428591</gml:upperCorner> </gml:Envelope> </gml:boundedBy> -Jukka Rahkonen-
