Sajjad and Arun, Thanks for your replies. I have looked into using OSM as a source, but I need accurate temporal data. As OSM is user generated, changes to the map do not necessarily represent the actual date of construction. Changes are only recorded when a user notices a road has changed, and because PMGSY is a rural program, these road (most of which are under 1km) are often not recorded.
But maybe I'm missing something. I'll look into it again. Maybe I'll write a grant to hire some folks to go through these OSM files and match them to the 1+ lakh PMGSY projects. Again, thanks for your input.
