One-to-many route calculations using Google Routes API
Click on the map to set an origin point. Destinations may be added either in census mode or postcode mode. Census mode takes several layers of census geography from Census Merged Local Authority Distrcits (i.e. 'Leeds'), to MSOAs (i.e. 'E02002330 : Leeds 001'), LSOAs (i.e. 'E01030525 : Mole Valley 008B'). Postcode mode takes either full postcodes or outcodes.
The results can be output as either GeoJSON polylines or a summary .csv file.
