WCPS1.5_Scaling on irregular axes is not supported

[Dimitar Misev]

Spawned from #823, should be investigated why is scaling not possible on irregular axes.

​http://212.201.49.21:8080/rasdaman/ows/wcs?SERVICE=WCS&VERSION=2.0.1&REQUEST=GetCoverage&CoverageId=irr_cube_2&SCALEFACTOR=2.0
should return a gmlcov, the exception is as below:

    <ows:Exception exceptionCode="UnsupportedCombination">
        <ows:ExceptionText>Error converting WCPS query to rasql query:
Scaling on irregular axis is not supported.</ows:ExceptionText>
    </ows:Exception>

can we do this now, or should we wait for CIS 1.1 to implement it?

[Bang Pham Huu]

Test in my petascope, returns a gmlcov correctly, maybe it has been fixed?

the grid vectors are missing in the above output, they are the critical part: are they scaled properly?

[Bang Pham Huu]

You can see the full diff in here (left scale 2.0, right not scale)

From my view, it is scaled correctly

<GridEnvelope>		                     <GridEnvelope>
   <low>0 0 0</low>		                   <low>0 0 0</low>
   <high>30 17 1</high>		                   <high>62 35 3</high>
</GridEnvelope>		                     </GridEnvelope>

That looks valid to me, can someone else in addition check ​https://www.diffchecker.com/6jeqamms

[Bang Pham Huu]

This ticket can be closed soon if Alex/Vlad has a confirm from ​https://www.diffchecker.com/6jeqamms

[Alex Dumitru]

This seems expected behaviour based on Bang's example so let's close it.
