The Digital Roads Atlas (DRA) is received monthly via GeoBC/Province of BC. The DRA is a data management system representing a complete and accurate road
network of all the roads in British Columbia. The DRA includes a combination of spatial data (such as road geometry) and attribute data (such as surface type and address information). It includes all types of roads, from resource roads to alleyways. The road information is obtained from aerial photos or roads driven with GPS referencing. Roads and intersections are represented geometrically as centrelines and points, respectively. |
