Dear IndiaGII, Rolf Kleef rolf@drostan.org drew attention to the OpenStreetMap project and wrote something of relevance to our part of the world. Rolf commented as below, but meanwhile could you please help to take these initiatives ahead, if you see something good coming of it? --FN PS: Apologies for cross-posting, just trying to build the links...

I'm copying a message I found with possible contacts, and especially want to point out possible work by FSF India on uploading map data via SMS and possibly developing free GPS devices. I don't know anything further about this. Maybe Frederick or others in APC have access to more information? It could be a valuable development to enable more participation worldwide.

Hi Ante
I'm also very interested in mapping India.
A couple notes on those data sources...
I've talked to Schuyler about this, he's one of the organizers of the Mumbai Freemap. Mumbai Freemap is an impressive data set -- it covers all of Mumbai, from digitized municipal documents. Issue is that it's currently not in a form usable for OpenStreetMap. The digitization was done in CAD, and is pretty directly a trace of those original documents. For example, both sides of the road are drawn precisely, but there's not single object representing the road itself.
So a second workshop would need to be organized, to transform the current freemap into OpenStreetMap. Technically this is quite simple -- the mumbai freemap can serve WMS, which can be read into JOSM. In JOSM, that imagery is retraced in the "OSM way". It's a lot of work, but my impression is that there's a lot of people in Mumbai willing to work very hard on this, and that with some organizational effort it's entirely doable.
I'd be up for helping on this.
AND in India is basically VMAP0. So we're talking major roads, somewhat out of data, but no detail within cities. VMAP0 contains other layers like rail, not sure if that's included in the AND data set. When I was last in India, VMAP0 was actually pretty decent for major roads, though anything built within the last few years was missing.
Still a good start, and since that import path is already worked out for the NL data, it makes a lot of sense to push that ahead too.

I met Nagarjuna G, chairman of the FSF India. One of the projects he is working on is open map data in India. They are experimenting with things like uploading tracks via sms. They would like to buy gps chips and build their own devices. Especially in Mumbai mappers are active.
I told him AND offered the main roads of India to OSM. He was very interested.
I'm rather ignorant about OSM's international contacts, so I just tried google. This seems to be the project Nagarjuna talked about:
These pages suggest there are already contacts between openstreetmap.org and mappers in India:
http://www.freemap.in/ http://wiki.freemap.in/moin.cgi/HbcseWorkshop The second one mentions the openstreetmap editor JOSM. Actually, I see his name as a workshop leader there too. If JOSM is used in India too, it should be doable to exchange data.
India is rather empty on our map yet: http://www.informationfreeway.org/?lat=15.686938643550643&lon=76.8613690...
Converting the AND data should be rather straithforward since we already have a conversion script. Intergrating it may be not too much work since most of our map is empty. It will be more difficult to integrate it with data collected by the India project. But that is where it starts to become interesting.
vriendelijke groet, cordialmente,
Ante
