Precise coordinates
octavo opened this issue · comments
The user would like vespucci to get precise user coordinates to map points, like fire hydrants.
I don't quite understand what the request is.
Note that you can already query the current position and create an object there, and move a node to a manually specified position.
The user would like to map the point with an accuracy value. The user would like to map the point again for increased accuracy. The user would like to waypoint average on a phone.
There isn't really a big advantage to (short term) averaging because the major component of errors in a GPS position are systematic, that is difference between reality and the model of the ionosphere used and other issues for example reflections.
There is a case to be made for some kind of PPP support which uses "raw" GPS data from the device (you can easily already do this with an external receiver and there are a number of Vespucci users that do that), but that is a larger undertaking as there is no ready made library available for this.
Note that this is in any case a duplicate of #900 pls continue the discussion there.
Just a PS: if you simply want to wait till the position has stabilized, for example because you were moving and now at rest, you can use the "Current position info" function in the location menu so display a continuously updated position and use that to create a node at that position.
