MapFactor Forum

Hi,

I assume that you use the "(Ramer–)Douglas–Peucker" algorithm in your map generation to simplify ways and so on, but how does that work in your map generation process?
I'm sure I did some "tagging" to (small) road segments. If you (MapFactor) simplify these roads (OSM ways), do you simply remove parts and thereby lose some of the tagging, or do you only simplify ways with the same tagging?

If you have something like
 _____X                      |
        \_X__________X_______X___
                             |
   A   B      C         D      E

A-E way segments (road segments); X the nodes.
You could simplify C & D into one way part, but if D has different tagging (like turn=, turn:lanes=, destination:lanes=, destination:ref:lanes= and destination:int_ref:lanes=) which are normally in the last part of a way before a junction, you would lose these if you simply only looked at simplifying the curve in the way.
I did some heavy tagging up to 30 August. All tagging is there in OSM, but it is not always reflected in the Navigator maps.

So: how do you process (linear) curves (if you use Ramer–Douglas–Peucker)?
