Hi,
How to make a successful test with the nurc__Img_Sample demo coverage
http://localhost:8080/geoserver/wcs?service=WCS&version=2.0.1&request=describecoverage&coverageid=nurc__Img_Sample
Check the axis labels from the boundedBy Envelope, for me they are axisLabels="Lat Long". So use them in the most simple request:
http://localhost:8080/geoserver/wcs?service=WCS&version=2.0.1&request=GetCoverage&coverageid=nurc__Img_Sample&&SUBSET=Lat(20,30)&SUBSET=Long(-130,-100)
Axis labels seem to be case sensitive for GeoServer and "lat" does not mean the same as "Lat"
I verified also the SUBSETTINGCRS does not make trouble at least in this request:
http://localhost:8080/geoserver/wcs?service=WCS&version=2.0.1&request=GetCoverage&coverageid=nurc__Img_Sample&&SUBSET=Lat(20,30)&SUBSET=Long(-130,-100)&SUBSETTINGCRS=http://www.opengis.net/def/crs/EPSG/0/4326
You can
I have noticed that Geoserver is sending wrong envelope for the non-flipped Easting-Northing projections. This is from the demo coverage nurc__Pk50095
<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>
Here the labels E and N are correct but the first coordinate in the Envelope is not Easting but it is Northing.

Try
Where 'lat', and 'long' are the names of the axes reported in your GetCapabilities response.

Subject: [Geoserver-users] Cannot specify subset in WCS 2.0.1Hello,
I'm trying to make a WCS GetCoverage call on a subset of a coverage
like
below:https://localhost:8080/geoserver/wcs?SERVICE=WCS&Version=2.0.1&REQUE
ST=GetCoverage&CoverageID=test&format=image/geotiff&SUBSETTINGCRS
=http://www.opengis.net/def/crs/EPSG/0/4326&outputcrs=http://www.op
engis.net/def/crs/EPSG/0/4326&SUBSET=lat(34.53627,38.88686)&SUBSET=lo
ng(25.43366,31.32234)But it keeps complaining with the error
<ows:ExceptionReport xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:ows=http://www.opengis.net/ows/2.0
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.0.0"
xsi:schemaLocation="http://www.opengis.net/ows/2.0
http://schemas.opengis.net/ows/2.0/owsExceptionReport.xsd"><ows:Exception exceptionCode="InvalidAxisLabel" locator="lat">
<ows:ExceptionText>Invalid axis label provided: lat
</ows:ExceptionText></ows:Exception>
</ows:ExceptionReport>
I have tried multiple axis labels, including latitude, x, y, long,
etc. listed in the
http://mapserver.org/ogc/wcs_server.html#wcs-2-0-kvp-request-
parameters <http://mapserver.org/ogc/wcs_server.html#wcs-2-0-kvp-
request-parameters> , but GeoServer seems to not like it all.What's the current correct format of specifying subset? I'm using
GeoServer 2.8.Thanks.
