Binds a QML item to a specific geodetic location in screen coordinates.
@ Incomplete
Data is missing and some error occurred when trying to retrieve it (e.g. network failure)
@ WaitingForData
Rendering is based on no or partial data, more data was requested (e.g. pending network queries)
@ Complete
All data is there and up to date.
@ WaitingForUpdate
Rendering is based on complete, but outdated data, data update was requested.
