That looks amazing. I went through your wikipedia page, and it seems you’ve been at this for a while. Would love to get your perspectives on the challenges faced, what worked, what didn’t, since India and Bangladesh share a lot of similar challenges - especially in terms of approaching institutions for information that can further the process really fast. I look at the map of just my neighborhood in Dhaka and how far its left to get it close to my old neighborhood in San Francisco and I get anxious! But the scale is even more immense in India!

I am trying to get the shape files for certain terrain and administrative regions and also for lat/long of public institutions like schools, medical and government service centers in Bangladesh and it has been slow and a lot of red tape so far.
