This national French API provides point-based location data for underground cavities, covering the Gironde department. Maintained by the Bureau de recherches géologiques et minières (BRGM), the French geological survey, the dataset identifies known cavity sites and is also available for download in AutoCAD DWG format. It supports land-use planning, geotechnical risk assessment, and hazard mapping related to ground subsidence in areas affected by natural or man-made underground voids. Access is free and does not require authentication.Dictionnaire Public Ce jeu de données localise par un ponctuel les cavités sous-terraines sur le territoire Girondin. Ce jeu de données est disponible dans un format additionnel : Téléchargement au format AutoCAD DWG
