Road network improvements in Indonesia

Hello, my name is Andrew, I work for Apple on the Maps team. My team is interested in doing some work on the road network in Indonesia on OpenStreetMap, things like adding missing roads, making sure roads connect properly, fixing incorrect alignments, ensuring road classifications are consistent, and other similar issues. We may also do some improvements to other data such as coastlines, water, and others if we find issues, but the main focus to start is roads.

Are there places you know of that need improvement or types of problems you see frequently? Also I saw these guidelines, are they the most recent road classification guidelines used by the community, or are there any others we should be aware of? https://wiki.openstreetmap.org/wiki/Wik … _Indonesia

We have a Github page here about the project: https://github.com/osmlab/appledata/issues/151

Please let me know if you have any suggestions or feedback.

Thank you,
Andrew

Re: Road network improvements in Indonesia

Also, we recently used our Atlas data analysis tool (https://github.com/osmlab/atlas) to look at a few types of potential issues related to roads and routing, such as roads that have overly sharp angles, roads that cross but don't connect, routing problems, turn restrictions, places where navigation is impossible due to missing connections or potentially incorrect one-way roads, and other similar issues.

I've posted the results of those checks on MapRoulette, a tool that lets you go through potential issues one by one and either correct them or indicate they are not a problem. I wanted to let you know they are available in case others wanted to try fixing some of them — I also plan to go through some of them myself.

In MapRoulette you can either pick a random task to fix or click on a specific one. If you want to do tasks around a certain location, such as somewhere you are familiar with, you can click on one from the map view, and then click Next task: Nearby when you finish it. Here are the challenges:

Floating and disconnected roads: https://maproulette.org/browse/challenges/8700
Impossible routing: https://maproulette.org/browse/challenges/8696
Connectivity check: https://maproulette.org/browse/challenges/8697
Invalid lanes: https://maproulette.org/browse/challenges/8702
Invalid turn restrictions: https://maproulette.org/browse/challenges/8703
Crossing roads: https://maproulette.org/browse/challenges/8698
Sharp angle roads: https://maproulette.org/browse/challenges/8699
Malformed roundabouts: https://maproulette.org/browse/challenges/8704
Road link check: https://maproulette.org/browse/challenges/8706
