New-Aquitaine: Primary roads BDTopo

BDTopo primary roads on the New Aquitaine region. The TOPO® BD version 2.2 contains a 3D vector description (structured into objects) of the elements of the territory and its infrastructures, of metric accuracy. It is delivered pre-symbolised in the most common proprietary formats on the market. The objects of the BDTopo® are structured into themes: — the road network and its address — the railway network — the energy transmission network — the hydrographic network — buildings — tree vegetation — orography — administrative structure — points of activity or interest (PAI) — the toponyms of the places mentioned. The 3D production process provides the altimetry of the objects, as well as the height of the buildings. The relief is described in the form of numerical terrain models (NTMs). In version 2.2, all objects have a unique identifier that is stable over time.
