Default Coordinates GPS position 0.0,0.0 and latitude 0 should not be send
From looking at the MQTT data and map of the global channel it looks like some nodes report their latitude, longitude and altitude as "0".
{"channelId":"LongSlow","gatewayId":"!a84c7038","packet":{"from":1230671069,"to":-1,"channel":177,"decoded":{"latitudeI":0,"longitudeI":0,"altitude":0,"batteryLevel":33,"time":1639753585},"id":1481766144,"rxTime":1639753583,"rxSnr":5.25,"hopLimit":1,"wantAck":false,"priority":"UNSET","rxRssi":-36}}
From looking at the code (https://github.com/meshtastic/Meshtastic-device/blob/6fc3c9c8689e754869097b797c6d9dfe101cc182/src/gps/GeoCoord.h#L85) it seems that those values get initialized as 0 and are sent like this later on.
The behaviour should be changed so that values that can't be determined do not default to 0 and are not reported / used at all.
This would come from the backend. latitudeI and longitudeI are not in the device.
