Hundreds of laser scans were completed around Tlatelolco including at the Ex-convento de Tlatelolco which today houses an important historical archive.

Supporting Conservation

The data collected is being used to support the conservation of these important buildings, many of which have experienced damage from earthquakes and subsidence.

LiDAR Data

In this laser scan, you can easily see how the three towers of the Chihuaha building in Tlatelolco are leaning at different angles caused by subsidence and shifts due to tectonic activity. 

In some parts of Mexico City, the city sinks more than 20 inches (50cm) per year due to subsidence.

Laser scanning is a quick method, experts can use to quantify and better understand the changes occurring in the urban fabric of the city. Learn more about CyArk's work in Mexico here.
