abstract: "La BD TOPO® est une description vectorielle 3D (structurée en objets) des éléments du territoire et de ses infrastructures, de précision métrique, exploitable à des échelles allant du 1 : 5 000 au 1 : 50 000.\n\nElle couvre de manière cohérente l’ensemble des entités géographiques et administratives du territoire national.\nElle permet la visualisation, le positionnement, la simulation au service de l’analyse et de la gestion \nopérationnelle du territoire.\nLa description des objets géographiques en 3D permet de représenter de façon réaliste les analyses spatiales\nutiles aux processus de décision dans le cadre d’études diverses.\n\nLa carte correspondante peut être\n[générée ici pour St Léger les Vignes, zoom 14](id.php/geodata/bdtopo/map/display?latlon=47.135,-1.730&zoom=14).\n"
