show beacon transmitter on ttnmapper

[TwentySixer]

As already discussed in the chat here the issue ;)

Actually my colleagues and I have an idea to place LoraWAN nodes to fixes places to measure the coverage of our gateways.
We would also like to provide this data to the ttnmapper but there is a problem.
We do not want to send the geocoordinate data in the payload, since you would have to store them in the firmware and you cannot use the nodes flexibly.
In the ttn-console it is possible to maintain a location for each device, longitude, latitude, height.
This data is included in the metadata.

metadata:
{
"time": "2020-01-22T09:15:09.746106679Z",
"frequency": 867.1,
"modulation": "LORA",
"data_rate": "SF7BW125",
"coding_rate": "4/5",
"gateways": [
{
"gtw_id": "eui-60c5a8fffe74d441",
"timestamp": 1614987531,
"time": "",
"channel": 3,
"rssi": -73,
"snr": 8,
"latitude": 51.55006,
"longitude": 12.137772,
"altitude": 3,
"location_source": "registry"
}
],
"latitude": 51.549404,
"longitude": 12.138148,
"altitude": 97,
"location_source": "registry"
}

It would be nice if the entered coordinates of the TTN console are used if none are delivered in the payload

Thanks in advance

For TTNv2 this has been implemented a couple of months ago. It still needs to be added for TTSv3.
