Rasql_project() missing geo-reference with NetCDF

[Bang Pham Huu]

When use crsTranform() in WCPS it return a coverage in NetCDF without georeference.

Update: The problem only happens if use a coverage with multibands (ranges) and encode all of these ranges in NetCDF. In this example: test_projection has 3 bands (Red, Green, Blue).

Describe Coverage metadata: https://www.diffchecker.com/9uk36tkw

If only select 1 band (Red) then it will have the full geo-referenced metadata.

WCPS query with metadata (select 1 band)

for c in (test_projection),  d in (eobstest) 
return encode(crsTransform((c.Red),
 { Lat:"http://www.opengis.net/def/crs/EPSG/0/3542", Long:"http://www.opengis.net/def/crs/EPSG/0/3542"}, {}), "netcdf")

WCPS query without metadata (multibands)

for c in (test_projection),  d in (test_projection) 
return encode(crsTransform((c + d),
 { Lat:"http://www.opengis.net/def/crs/EPSG/0/3542", Long:"http://www.opengis.net/def/crs/EPSG/0/3542"}, {}), "netcdf")
