And it so happens that i managed to get a handle on all the zip codes in India and their corresponding longitudes-latitudes. This is what you get when you connect all the zipcodes in India :
And then when you order the long-lat pairs :
The next in this series is going to be :
1) Calculate the total distance travelled when you connect all the zipcodes (from map#1).
2) Do a TSP(Travelling Salesman Problem) on the zipcodes (from #1 above) and plot the route. Calculate the distance.
3) Do #2 for each of the states. (this "can" be used when you are planning your travel)
