Heinz, the calculations were done a few weeks ago, but its still interesting to note the differences in length. If you can share the process you followed to do this it will help find the cause of the variation.

if I can’t get free data, let’s build it from scratch and share to anyone!

And when I think back, this was probably the line of thought that got me involved as well.

Amazing work Maning, its so great to see how all these efforts from various parts of the world have been the threads to help weave this beautiful carpet for everyone. Can’t even imagine what we will see in another 10 years!

It will be worthwhile to investigate to root cause of so many broken relations and how to reduce more breakage in the future. Working with relations definitely require a higher level of skill than other data types.

Its great to know there are QA tools like http://map.comlu.com/ and http://restrictions.morbz.de/ which help detect and fix them. The only problem is that it took me a random glance into the diary to find this out and I suspect most editors don’t even know that such tools exist. It would be great if all important tools like these were somehow accessible directly from osm.org for more visibility.

This is amazing @baditaflorin, thank you so much!

@SomeoneElse Languages in India is a complex situation and one would see majority of the signboards use both a regional language and English or Hindi.

To simplify tagging on OSM, we have been using name to represent the English/Roman name as it would be the most usable. Even though most of India does not know English, the roman alphabet is ubiquitous and in common use.

This will be of immense value in india where poor electricity and internet services for large parts of the country makes projects like OSM and Wikipedia inaccessible.

wonder if this is your primary method to evaluate the work of your mappers and if not what your primary method is and what role this tool plays in your data team controlling.

This is a great question. The most valuable way to evaluate the output of an OSM mapping team is community validation of the work. Tools like these helps the community review our work and close the feedback loop with the team.

The team is skilled to be able to contribute both in quality and volume, and this allows us to make large scale map improvements in a relatively short time period like the recent review of sidewalks. Each quality edit improves the map positively and that is what is important. It would great to hear your suggestions on how and what we could be doing better.

Beautiful work!

5,370 volunteers have committed nearly 16 million map changes

Amazing!

Thanks Rub21, this really saved a lot of time when cleaning up the Japan data.

1. In Seto Inland Sea
2. Bhopal Airport Terminal osm.org/#map=16/23.2909/77.3368
3. School ground osm.org/#map=18/39.76643/-86.21198
4. Near Fiji, Japan

Nice work Aarthy, a plugin like this will be extremely useful to avoid mistakes due to human error in customizing the various setting in JOSM especially during HOT activations.

Where can I download the plugin/code? Would love to try it out.

Good suggestion imagico. In future we’ll keep the OSM scale bar.

Issue file in iD to suggest alternate imagery based on map location to help new mappers set the correct background layer: https://github.com/openstreetmap/iD/issues/2826

Great work!Looks like there was someone else from Jorhat mapping too, you can try to check the history of objects and getting in touch.

Also interesting is to make a map with Assamese labels and pass it on to the local authorities. As a region which is constantly flood prone, these are very valuable resources for those on the ground.

@SK53 Good call, this will be some valuable documentation to have for reference.

A point to note here is that growing a community in a place with broken data is quite a challenge. The AND imports in Mumbai was such a gigantic mess that the city of 18 million had 0 mappers till I manually cleaned it up singlehandedly over months. Its very discouraging for a new mapper to start off cleaning issues rather than building of the good work of others.

@RicoElectrico Unlike the western world of open source where mailman lists and irc are the norm, in Asian countries, people prefer social networks like fb and whatsapp to connect and communicate. Its a matter of convenience for each community to decide the language and mediums to talk to each other.

Just tried out the export tool and was very simple to use, great work!
