Estimation of the shortest paths from a building to join the PHC. a Shows an illustrative example of shortest paths obtained thought OSRM, with building values for travel distance and time to reach one of the district’s PHC b Shows how the travel distance calculated by OSRM improves on typical Euclidian distance estimations, providing more realistic and accurate values by using the footpath network
