Maps and plans (2D) are still the main resource to represent and consequently manage a city, a state and a complete country in Latin America. However, new trends in design and construction, together with accelerated geotechnical advances are changing the paradigms of the public policy. Currently, technology allows to manage complex objects in space (3D), changing the way that the territory, the property rights and their restrictions are described. Infrastructure and transport networks move through space in different ways, some are invisible by nature, such as cell phone microwaves, and others are invisible because they are underground, such as tunnels and pipes. Other networks are visible because they are built on the surface, such as roads and electrical service cables. The spatial relationships between networks and public and private properties, informal occupations, environmental reserves, mineral deposits and bodies of water have not been dealt with efficiently through 2D representations, so they require strategies to move to the 3D world. Structuring territorial cadastres and service networks in 3D is taking time along the region. It is in this context that the present work describes the processes used in Mexico to survey and represent everything related to power lines and proposes a gradual construction strategy for a cadastre 3D.
