Hi! I’m a musician, programmer, and proponent of free software, free data, free culture, and privacy.
As a software freedom advocate, I boycott all proprietary software. For that reason, I improve OSM every chance I get, in the hope of making libre software like Organic Maps, OsmAnd, and OsmAPP a viable alternative to proprietary maps. I use…
* Vespucci for mobile mapping,
* OpenCamera for geotagged photos,
* JOSM for public transport,
* OpenTracks (and earlier OsmAnd~) for recording tracks and waypoints.
* MapComplete for adding ratings and reviews to Mangrove Reviews.
I like contributing all kinds of public transport data - nearly all bus routes in Delhi are my work.
Since 2023, I’ve been organizing monthly mapping parties in Delhi and NCR. See the OSM India Mastodon (with photos!), or the forum thread.
I’m proud to have done a professional ground survey for Médecins sans frontières (a.k.a. Doctors Without Borders), in Delhi’s Bhalaswa, Adarsh Nagar, and Jahangirpuri regions.
I conduct OSM workshops in colleges, e.g. at IIT Roorkee in collaboration with HOT.
I’ve also organized OSM tables, talks, and workshops at conferences like IndiaFOSS, DelhiFOSS, and FOSS Meetup Delhi. I have a Git repository containing my (libre) designs for a variety of OSM promotional material.
