I am trying to prepare a base map of road network of Cooch Behar District of West Bengal, India. I have been trying to download the OpenStreetMap (OSM) for the district but found that many roads are missing in the downloaded shapefile. I have also tried to download the same area from geofabrik and the issue remains the same. I saw when I downloaded the same from a small area all roads came but I need the complete road network shape file for the entire district.
I have decided to purchase the road network shapefile for the area but the cost is huge.
