Digital road network

Road network

The previous digital road network of Saint Lucia was digitised from satellite imagery. During the RMMS project the entire digital road network is redone. Currently, most of the ABC roads have been now surveyed, post-processed, cleaned, coded, verified and imported in the road asset database. The advantage of surveying the road alignment with GPS instead of satellite images is higher accuracy for altitude, which is important when road lengths are calculated correctly. Establishment of the digital road network is on-going for lesser roads.
