GUNW product - gridmapping/z-values missing as meta-data for radarGrid fields #7
Description
Hi,
The GUNW product works well with the netcdf reader for the data layers, for plotting in QGIS, panopoly etc.
Confirm this both for the public product and a product created internally (as of 20 Feb). Below is consistent between both the public and internal version of GUNW created:
For the radarGrid:
- there seems to be a meta-data variable missing that identifies the
projectionvariable in the same folder to be the grid. - I also cdid not see a mapping to the
heightAboveEllipsoidfor the z-values.
Screenshots for radarGrid illustration
Details
see the difference between unwrapped layer meta-data (has projection and x-y coordinates referenced):
parallelBaseline meta-date layer (does not have projection, also z-coordinates aka heightAboveEllipsoid are not included):
Following could be used to replicate expected behavior
Details
For Unwrapped phase this is the output as expected using the netcdf drives (given CF compliance)

For the cubes we would expect something alike recognizing projection but also incorporating the Z-dimension
Below is the current produced output:

Separate note for GUNW product
Suspect this is already fixed (only applied to the public sample and not internally created product).
