Cartonama, Open Mapping in BangalorePosted: March 29th, 2012 | Author: mikel | Filed under: events, India, talks, tech | Leave a comment »
The keystone to GroundTruth’s trip to India was the Cartonama workshop in Bangalore.
My comrade in maps was the amazing Schuyler Erle, in a reprise of our epic 2008 Free Map India tour. India, Banalore, and its OpenStreetMap have transformed (as you can see in this heart-filled animation of OSM Bangalore). This time, rather than visit 7 cities in 4 weeks, we crammed even more information into two days. As ever, I learned a ton from Schuyler. Perhaps the choicest bit being, “Canada is often projected as if the Earth was wearing a dunce cap”.
This was an intense two day workshop, covering everything needed to make an open web mapping application: from data collection in OpenStreetMap, to data juggling with OGR/PostGIS etc, making tiles with TileMill, and finally building an Ajax Web app with Leaflet and the OSM API. Oh, and also a survey of basic geographic concepts (geodesy, projections, etc), and the intricacies of the operation of GPS satellites. Really it was four workshops in one. Or maybe 10. Possibly a semesters worth. I think it’s a format worth replicating.
The end result was a modification to the amazing POSM POSM by Yuvi Panda. He built this HTML5 web app for first collecting bus stops in Mumbai. There were wonderful audible gasps when we integrated our home baked MapBox tiles into the locally running POSM app (even if we discovered lingering problems with handling of Indic fonts in Mapnik).
Cartonama was an Editor’s Pick in TimeOut!
Another great moment, during the ice breaker we stole from Gunner: “What’s your first memory of a computer?” “We had to take our shoes off before going in the lab because computers are holy, right?”
HasGeek did a wonderful job bringing bringing the workshop together, and are lighting up the geek event space in India. They’re really fostering community in the best way, and I’m excited to see what happens with all the mappers from our workshop, and the upcoming full Cartonama conference. So big thanks to HasGeek, and the Centre for Internet and Society for hosting and sponsoring the workshop.
