This API provides the location and description of stormwater collectors within the Angers Loire Métropole territory in France, maintained by Angers Loire Métropole. The dataset, described as still under construction, includes a unique identifier for each object and its type, classified according to the collector's shape, such as circular, box culvert, engineering structure, ovoid, pipe, or unspecified. It is intended for use in mapping and managing local stormwater drainage infrastructure.Localisation et description des collecteurs. Base de données en construction.
