Beers to you!

Amazing, this is a great example of how valuable projects like HOTOSM are for developing nations like India where millions of citizens are vulnerable to disasters like cyclones and flooding. Nice work all!

Having set foot in the Rann, its essentially a very large mudflat crusted with an inch of salt, atleast when its not submerged. There is a very clear boundary where land ends and the saltmarsh begins, but its unclear where the marsh ends and the coastline begins.

The Rann during monsoon and when its dry. NASA

Have tried cleaning up this area before, but it just seemed unclear how to proceed. Nobody has brought it up for discussion in the Indian community either.

Maps in India usually depict it like this:

Btw, great post. its interesting how humans so far away geographically evolve very similiar habitations.

This is very similar to the structure of villages in India near the deserts in the northwest. The compound is essentially a fenced land that includes multiple landuses.

My suggestions for tags is to use barrier=fence for the perimeter and landuse=’residential’ for the enclosed property. The gardens and crops within a very much residential in nature and are completely for domestic consumption than to sell to a market.

SomeoneElse, the ground mapper is always the most important part of the process. The objective with tools like these is to allow ground mappers to easily modify and run an analysis for their areas of interest and fix it themselves. These are still early days of trials and testing the output and its great to detect such issues early on rather than later.

What you highlight is an issue worth solving, there are many mappers in the world who are interested in data ‘gardening’ of areas outside where they live, and we need to see how we can build tools to support such needs. Whats a reliable definition of what constitutes an area that has a ‘reasonable concentration of mappers’? Checking the history of each way or visual check of completeness cannot always work. Maybe evaluating the average freshness for the data in an area?

It might then be possible to easily distinguish which are areas with active communities that one can get in touch with for ground support or alternatively such cleanup tasks could ignore these areas altogether.

^ sorry, that came from me, left my new LA buildings account logged in..

Fantastic work Manoj!

Can’t really recommend one over the other since I have not tried generating vector tiles myself. My guess is that the standard osm2pgsql/postgres setup should work.

And yet another is to use the OSM QA tiles that are updated daily, although these do not yet support relations.

Another workflow is to use minjur to convert OSM data into geojson and tippecanoe for conversion into vector tiles.

pnorman, the first step is to create vector tiles of the data you want to render. One can do this from a regular mapnik source using https://github.com/mapbox/tilelive-bridge .

Next is to use a JS library like https://www.mapbox.com/mapbox-gl-js/api/ to request vector tiles and render them on the client side using a GL stylesheet https://www.mapbox.com/mapbox-gl-style-spec/ which will give the same results.

The hard lift in the process is to manage vector tiles and keep them in sync with OSM data. This is essentially what is simplified by using Mapbox hosted vector tiles.

It seems like the end of the year sees a regular pattern of drops .

This is amazing, maps.me has been the most user friendly OSM app i’ve used by far. Going to try editing tomorrow.

One of the very interesting observations in Indian cities were they all evolved from little villages or grew around a fort a large temple. The patterns of streets and buildings are organic and radiate along directions that are the shortest path to the next village or settlement.

This is very different from the gridded cities of US, where the convenience of the planner took precedence over the plan or aspirations of the residents.

MapMakinMeyers: The query for the raw data is in the post: http://overpass-turbo.eu/s/f5N

Vincent de Phily: Thank you. The boundaries on OSM was updated using various sources, should have clarified that.

Yes, we don’t have a consistent addressing scheme or street signages in India. Finding a home usually involves asking for a landmark like an important junction, building or shop and then asking the local people for the exact house.

This is an amazing exercise. We have really poor footpath infrastructure in India, especially in terms of accessibility for visually impaired and those on a wheelchair, although I suspect Kerala is far ahead on these matters.

Every community has their own approach to tagging footpaths as separate ways. I’m for mapping them separate especially in town centers with heavy foot traffic, this allows for much more precise pedestrian routing. But on residential roads, it makes more sense to have it as an added attribute sidewalk on the road.

It seems like the common understanding of a halt is a minor station with limited services on the railway line. With this definition, it certainly does not make sense to tag subway stations as halts.

Would there be a better way to tag the type of a station, especially terminal stations and interchanges which one would want to be more visible on a map?

Awesome! Wish there was a MapCSS setting to not display small features as POIs so everyone can see the same style.
