Hi Mark,
Thanks for your response.
OK, pixels don't have an ID but I meant to identify the response with the
request. The example was with 4 layers, but the idea is that it can be 'n'
layers requested so I get 'n' values in the same response so I need a way to
match the value and the layer requested.
This is the response in json format
{"type":"Feature","id":"","geometry":null,"properties":{"GRAY_INDEX":11735}}
{"type":"Feature","id":"","geometry":null,"properties":{"GRAY_INDEX":15902}}
{"type":"Feature","id":"","geometry":null,"properties":{"GRAY_INDEX":16547}}
In this response I can't match the value with layer directly. There's no way.
But, if I do the same request, talking about more than 1 layer in the same
request, but using application/vnd.ogc.gml I get a GML file in which I have the
value linked to the layer name:
<gml:featureMember>
<TELEDETEKZIOA:S2A_20170512T111302456Z_NDVI fid="">
<TELEDETEKZIOA:GRAY_INDEX>11735.0</TELEDETEKZIOA:GRAY_INDEX>
</TELEDETEKZIOA:S2A_20170512T111302456Z_NDVI>
</gml:featureMember>
<gml:featureMember>
<TELEDETEKZIOA:S2A_20170422T111300457Z_NDVI fid="">
<TELEDETEKZIOA:GRAY_INDEX>15902.0</TELEDETEKZIOA:GRAY_INDEX>
</TELEDETEKZIOA:S2A_20170422T111300457Z_NDVI>
</gml:featureMember>
So in each featureMember I get a tag with the Workspace:Layername. That's why I
was asking..
Thanks.

I don't think pixels have an id or a geometry, they are not actually features
It would be great to have the layer name there to identify the requested layer
and the returned value..
but you already now the layer because you have just requested data from it?...
Just like if the INFO_FORMAT is application/vnd.ogc.gml
the gml does not provide the layername and if you look closely does not provide
a fid or a geometry, so the behaviour is the same for both types of response.
