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?

We have a Github page here about the project:

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

Thank you,
Apple, Inc.

Also, we recently used our Atlas data analysis tool ( 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:
Impossible routing:
Connectivity check:
Invalid lanes:
Invalid turn restrictions:
Crossing roads:
Sharp angle roads:
Malformed roundabouts:
Road link check:

This is Andrew again with Apple. In addition to the road network improvements I messaged about before, we are planning to work on some limited data corrections and improvements to OSM in Indonesia around coastal and water features and land use and land cover polygons, such as parks, university and hospital campuses, airports and similar features.

For example, sometimes coastlines and national parks are missing a correct tag, or are digitized inaccurately (maybe due to old low resolution imagery). We will make sure to follow the appropriate OSM and local guidelines. We have been doing a similar project around Africa and in other regions for some time.

Also, thanks to those who contributed to the MapRoulette challenges I posted earlier! I have posted them all here:

I wanted to get your feedback and see if you had any suggestions or data resources we could use.
