OpenStreetMap
I started with mapping roughly I year ago. At this time Korea was more or less a white spot. Since I´m travelling a lot on highways I did a lot to collect data and mapped as two oneway lanes and connected carefully the junctions and IC´s.
In the meantime I have to recognize that some stupids are deleting my work and either replace the nicely prepared curves with a few dots or just delete. Only repairing my work is not real fun.
I do not know why peaple are doing something like this.
As I have other things to do I´m deeply considering to stop my activities in mapping and leave.
Maybe somebody has the same experience or knows how to protect.
Best regards vineldi

I have not seen any vandalism on OSM so far, but there is probably some. However, most changes that make parts of the map worse than before are not malicious but simple mistakes. You can use the new area history function to find out who made a particular change and can just ask what the intention of it was. In case it was really vandalism, there are tools to "undo" a changeset.

Maybe somebody has used the JOSM way optimizer which reduces the number of dots.
Optimizing increases the average distance between dots from 10 metres to roughly 50 metres, depending on curve degree. Optimizing reduces calculation time for routing and database storage capacity.
Did you ever try to use the JOSM way optimizer?

Optimizing Ways should not touch the route calculation time, if it does it's a bug ;)
(It might reduce the time to prepare the data for the routing engine, though)

Optimizing Ways does not reduce database storage capacity - at least in main server. But you are right for exports.

Hello all together,
I´m not complaining about optimizing the way via the JOSM optimizer function. In some cases the road is replaced by another road not created by JOSM but some other tool (I do not have in mind and have to check). Bridges and tunnels are deleted and connections to interchanges are cutted. In addition these roads are made only very roughly (as mentioned in my previous blog).
In the other case a part of a highway (let´s call it the the northward bound part) is simply erased (maybe peaople think highway as double lane is enough). But also in that case all IC´s and junctions are cutted.
Dear lyx,
here in Korea I´m sometimes facing the problem that the people doing something strange to map are unable to understand English language so it is hard to ask them why they did and even harder to explain taht they something wrong.
But maybe I´m wrong in transferring the German approach to map a highway always as 2 roads in different direction is not longer applicable (in that case I´m asking myself how a routing SW can work on the OSM dataset).
If there is a chance to restore it would be helpful to know how.
Best regards + thanx a lot for your comments Dieter = vineldi

Maybe someone’s ladling in a lot of data without any regard for whether there’s anything better. Let’s hope their source is legitimate for copyright. If there’s a language barrier try contacting one of the Korean mappers to see if they can help.
