This dataset, published by Angers Loire Métropole (the intermunicipal authority around Angers, France), provides the location and description of stormwater drains (avaloirs) within its territory. It is described as a database still under construction. Each object is identified by a unique number (NUMERO) and classified by type (TYPE), distinguishing categories such as grates, drain openings with a cover plate, and drain openings with a grate. The data supports local stormwater infrastructure management and mapping.Localisation et description des avaloirs. Base de données en construction.
