It is centered on the office work focused on the property purification of more than 1032 properties belonging to Empresa de Acueducto y Alcantarillado de Bogotá (EAAB). The main purpose is to update the cadastral information of these properties, ensuring the accurate and updated representation of their boundaries, in accordance with current regulations. The importance of the Cadastre in Bogota for tax management and the need to keep the real estate information updated for the calculation of the property tax is highlighted. It is noted that the lack of updating of the EAAB's cartography has generated difficulties for land and infrastructure planning in the city.
