Basement Technical Cadastre (CTSS) - Geotechnical Point

APIExecutable4/7Query nowOpen workbench Subscribe🇨🇭Switzerland

This API provides access to the Technical Subsoil Cadastre (CTSS) for the canton of Geneva, Switzerland, focusing on geotechnical point data. It identifies and records underground objects such as pipes, constructions, and construction accessories located permanently in private and public subsoil that are not already listed in the official cadastre or in other specific infrastructure cadastres. The dataset is maintained by the Geneva territorial information system (SITG) and supports planning, construction, and infrastructure management activities requiring detailed knowledge of underground installations within the canton. Access is free and does not require authentication.The purpose of the technical basement cadastre (CTSS) is to identify and report all the objects of the pipes, constructions and construction accessories, occupying the private and public basement on a permanent basis, and not appearing in the official cadastre or in the specific cadastres of the pu…
