This API provides geolocated data on underground sections of medium-voltage (HTA) power lines belonging to French electricity distribution networks. HTA, also known as Moyenne Tension, generally covers voltages between 1,000 volts (1 kV) and 50,000 volts (50 kV). The dataset is published by Agence ORE (Organisation pour le Respect de l'Environnement dans les réseaux électriques), which aggregates network infrastructure data from French distribution system operators, and can be used to map underground medium-voltage cable routes across the national territory.Ce jeu de données permet de visualiser l’emplacement géographique des tronçons de ligne électrique souterraine moyenne tension des réseaux de distribution. La Haute Tension A ou HTA (ou Moyenne Tension) peut être comprise entre 1 000 volts (1 kV) et 50 000 volts (50 kV). En principe,…
