Missing elevation in DataStream

[enricoboldrini]

It seems that latitude and longitude are being set in datastream after observations are added to the stream, reading these values from the location. However the elevation is not copied.

To reproduce:

curl -s -X POST "${BASE_URL}Things" -H "Content-Type: application/json" -d '{"@iot.id":"1", "name":"mything","description":"mything"}'

curl -s -X POST "${BASE_URL}Things(1)/Locations" -H "Content-Type: application/json" -d '{ "name": "myloc","description": "myloc","encodingType": "application/geo+json",
"location": {
"type": "Point",
"coordinates": [44.5, 11.3, 50]
}
}'

curl -s -X POST "${BASE_URL}ObservedProperties" -H "Content-Type: application/json" -d '{"@iot.id":"2","name":"myop","description":"myop","definition":"myop"}'

curl -s -X POST "${BASE_URL}Sensors" -H "Content-Type: application/json" -d '{"@iot.id":"3","name":"mys","description":"mys","encodingType":"application/json","metadata":""}'

curl -s -X POST "${BASE_URL}Things(1)/Datastreams"
-H "Content-Type: application/json"
-d "{
"name": "myds",
"@iot.id": "4",
"description": "myds",
"observationType": "http://www.opengis.net/def/observationType/OGC-OM/2.0/OM_Measurement\",
"unitOfMeasurement": {"name": "degree", "symbol": "°", "definition": "http://unit\"},
"observedArea": {
"type": "Point",
"coordinates": [44.5, 11.3, 50]
},
"Sensor": {"@iot.id": 3},
"ObservedProperty": {"@iot.id": 2}
}"

At this point the Datastream has been uploaded, but trying to retrieve it no observedArea is present, even if it was present in the just uploaded json.

curl -s -X POST "${BASE_URL}Datastreams(4)/Observations" -H "Content-Type: application/json" -d '{"result": 12.5,"phenomenonTime": "2025-01-15T12:00:00.000Z" }'

At this point, after one observation has been uploaded the Datastream observed Area appear, but without the elevation:

"observedArea": {
"type": "Point",
"coordinates": [
44.5,
11.3
]
},

I've had a quick look, and currently the geometry column that the observedArea is calculated from is being flattened to 2D. Maybe that can be made configurable.
