Re: [Talk-in] Id editor on Bhuvan
Well, the foundation does exist. Does this mean everyone creates an account on Bhuvan before starting to trace in OpenStreetMap? I'm still not clear how this could work. Might make sense to ask others. Paul, Mikel - do you have thoughts? Would be good to know what Paul and Mikel think here. It seems a question of what is public domain, not just according to OSM but also per Indian law. Apart from the discussions on Bing and the License Working Group, this is the only statement I find on the OSM wiki: https://wiki.openstreetmap.org/wiki/Legal_FAQ#2._Contributing Hmm, 20 tiles a day is not going to work. This is going to be high traffic. And it does require reliable infrastructure. Worthwhile to consider how we can support Bhuvan on this. Also, few imagery are not in web mercator, those will have to be reprojected. Yes, agreed, the 20 per day limit I see is not just for GeoTIFF downloads but also for the tile service. There could perhaps then be a role for HBCSE-TIFR here as a educational institution, and government client able to redistribute and serve high-availability imagery for scientific and developmental purposes to the OSM community. The fact that Bhuvan is already using ID, tilecache, etc. is the opening I believe Nagarjuna was looking for when he initiated this thread. We are ready to approach NSRC and ISRO via TIFR to support using Bhuvan for OSM mapping, if folks here can advise on what we should ask for. We're also approaching them for raw data which we're using for image processing and analysis at HBCSE.

Re: [Talk-in] Id editor on Bhuvan
Nice, I finally poked at this. For those on list who don't know tiles
URL syntax, you can drop this URL into ID and it works great!
http://tile1.nrsc.gov.in/tilecache/tilecache.py/1.0.0/bhuvan_imagery2/{zoom}/{x}/{y}.jpg
The subdomain prefix tile1 can be replaced with tile2, 3, 4 (I
guess these are backup servers?)

Re: [Talk-in] Id editor on Bhuvan
Hey Shekhar -
Can we get more clarity on the license before we start using this please?
Again, we need it in writing that this is public domain or usable for
tracing in OpenStreetMap.
We cannot use it otherwise.
