I need to add a route layer for India in tilemill tool. how do i get data source from online for my particular place? |

Typically you would download the OSM data file (.osm.pbf format) either for all of India or for your region of interest, using one of the sources listed on the Export tab of the web site. Then you would use the osm2pgsql program to import this data into a PostGIS database they you have set up locally. Then you can use TileMill to access that database. Working with Shape Files is an alternative to a database install but depending on what you mean by "route layer", not all information you are interested in may be present in the shape file. |
Just in case you haven't see it already, I'd definitely run through TileMill's "crash course":
