Kepta, your work is huge in helping mappers build a more navigable OSM for their areas. Thank you!

@BushmanK if there are indeed rules on the map, we should ideally enforce it in the software end rather than poking newbies, which would get out of hand as more and more new contributors come in through new tools and not necessarily a mapping party like the old days. It feels like the system is way too liberal in allowing data to break which could otherwise be prevented at the source if the editors or the API rejected any changes which breaks the rules.

Nice find. One issue is that state governments in India lack a open data policy to share such information under an open license. The work to collect this data is usually contracted to a private organization which retains the copyright and does not even openly share it back with the government.

You can try to email the municipal authorities, but they likely will have no clue and may not respond. A personal visit to your local councillor or someone else in state authority with their written word that the data is good for use to be shared publicly with an attribution of their choice is all you would need to get this into OSM.

Nice work Atikur! Went through the video and its quite informative.

Since there is no audio or subtitles, it would help to add an index in the description which links to various parts, like: Trace a road etc

Cheers,

Well done! Especially looking forward to some local language maps of Vizag in Telugu.

Thanks for the great writeup! We’ve all been waiting years for such a meetup, looking forward to the next one.

bushman, its great that you are sharing this for others. Its amazing what we can do now with Sentinel and Landsat, but too much is hidden behind complex workflows and cryptic commands. I think more work is needed to simplify these instructions for the common man, right now it still feels like most documentation is targeted at a developer who is comfortable with the terminal or had background theory of satellites.

In my spare time while playing around with such data, I document my journey so that it could be useful for others, and while writing i’m constantly thinking how to appeal to someone who is 12 years old to do this. If it helps, here’s some of my material.

joost, the purpose of the tool was exactly to help such projects where we need to compare and merge data into OSM. I think i’ll need to do a bit more work till its easily customizable, tracking updates here: https://github.com/osmlab/data-mapper

Welcome to the OSM city of India, Maning! The contradictions on the street reflect the un mappable reality of life. Glad you are enjoying the new neighborhood :)

Little known fun fact about the city: This is where one of the largest mapping projects in world history began.

Like Vincent de Phily says, my biggest issue with w3w is its language specific. Why Mongolia would chose to impose English as a prerequisite on its citizens to find locations within the country is beyond me.

A wild idea is some kind of spherical coordinates using the closest globally recognized location like an IATA airport code.

Like BOM 13.62 121.2 -> 13.62km and 121.2degrees southeast of Mumbai International Airport, India

Sorry for ^, better formatted:

• Maps.me does a check for similiar POIs in the location using the OSM API/Overpass before uploading to OSM, or as an alternative create a de duplication tool for the community to easily review/fix changes from the editor. Maybe this will help create its own community of Maps.me reviewers.
• Add ability to create custom tags and presets. There are possible many folks using the editor for field data collection but using incorrect tags to overcome this limitation. I do this as well, and later use overpass to fix the tags, obviously not easy for everyone
• Provide more granular data updates to maps where users are contributing

This is more of a case of users hacking around the limitations of the Maps.me editor according to their own understanding rather than an import.

These improvements might largely solve the issues we’re seeing: - Maps.me does a check for similiar POIs in the location using the OSM API/Overpass before uploading to OSM, or as an alternative create a de duplication tool for the community to easily review/fix changes from the editor.

Updating the map is a manual process from the dump Jochen is generating everyday. Have not thought about an update cycle, but can do once a week till there is demand to do it more often.

JBacc1: Just tested on Chrome and Safari, can you open a ticket with any console errors you are seeing here: https://github.com/osmlab/fixing-polygons-in-osm/issues

Or maybe a cache issues? I updated the map yesterday to fix this.

Mateusz Konieczny: Thats right, it looks like theres always going to be cases where it would be impossible to predict what was right without a deeper investigation. Have made an edit in my post.

JBacc1: If you click on any feature you will get an Open in JOSM dialog. I’ll need to make it more explicit on the map. I guess.

Great to hear your positive experience, welcome to OpenStreetMap!

Nice work in your hometown, if you know the name of the streets you should add them as well.

This looks like an error in how empty turn lanes were detected and I just documented it on osmlint for correction. The context for the cleanup was the occurrence of tags like turn:lanes:backward=none|none|none and similar, and checking if the turn lanes count matches the number of lanes.

One of those two checks seems to have flagged such cases in error, and it was a mistake on the mapper part to not highlight the inconsistency as it was spotted.

Is this a common pattern on only two lane roads, or does such marking appear on larger highways as well? Weighing the option to either revert all the changes or just those that match a certain tag combination.

Such an amazing writeup! This brings the total count of trees mapped in the city to 2259.

Do you tag the tree stumps as trees as well? I’m always confused when a plant becomes a tree and now my benchmark is if its 1 building floor high, its a tree!

Interestingly the Siachen Glacier In the Himalayas has a similar history of lying in an undemarcated zone that is claimed by India and Pakistan. The situation changed in 1998 after a war broke out between the two and the Indian army finally took control of the highest battlefield on earth.

Thanks SomeoneElse for the backstory. Always fascinating to read a disputed border story :)
