Apologies for the blog spam but you don't find something about Indian Railways on hn everyday :) I recently tried visualization of routes and live running status of trains in India using jupyter notebook -- [http://abhirag.in/articles/train_of_thought_1.html http://abhirag.in/articles/train_of_thought_1.html]. Someone here might find it useful :)
- kalyan02 9y agoBrilliant. I love indian railways and keep wishing for frequent open data set releases. Looking at your notebooks, my interest has rekindled again. What are your thoughts on geocoding names of stations, to obtain GPS coordinates with better accuracy? It would largely be a one time effort imo.
- abhirag 9y agoThanks :) if you look at part 2 -- [http://abhirag.in/articles/train_of_thought_2.html http://abhirag.in/articles/train_of_thought_2.html] I already have a decent algorithm to find stations with wrong coordinates, regarding geocoding, if you zoom into the map, you will find that the stations are marked with a star so OpenStreetMaps presumably has that data already. Cleaning up the location data is definitely doable but wouldn't be easy. One main issue is the duplicate names of stations, although the station codes would be different, we still need to have a rough idea of where the station is. I did try and improve my results using the MapQuest geocoding api, but I would label that effort as "work under progress" for now :)
- cscurmudgeon 9y agoBeautiful. What theme are you using?
- abhirag 9y agoGlad you liked it :) I am not using any theme, custom built the css to my liking.
