Sandra Ponzo

Sandra Ponzo is an agrimensora and the Operational Manager of Physical Cadastre at the Urban Development Secretariat in Buenos Aires. She plays a crucial role in managing the city's topographic reference system, specifically the 'puntos fijos' or fixed points, which are essential for determining the elevation of various locations in the flat landscape of Buenos Aires. Her work ensures that these metal plaques, which indicate altitude relative to sea level, are preserved during construction projects, thus maintaining the integrity of the city's infrastructure.
