Topographic Monitoring: Tools for Risk Management

In this in-depth exploration of geodesy and topography as sciences that deal with the study of the Earth and the graphical representation of portions of its surface, we have outlined the evolution of the topographic surveying method through the use of topographic instruments in various fields of application.

We have seen how the total station, with its measurement precision and reliability, has found wide use in architectural and archaeological surveys, proving effective in challenging work environments.

We have also seen how the GPS and GNSS positioning method applied to topographic surveying allows for easy positioning of points on the Earth’s surface, even in complex operational conditions, giving the operator the ability to carry out their activities independently.

At this point in our exploration, we want to dedicate a brief reflection to topographic monitoring as an ongoing activity for territorial control, an area of great relevance closely connected to the need to verify the condition of buildings, structures, bridges, dams, tunnels, and landslides.

Topographic monitoring and risk management

The safety of structures represents a critical issue in our country. We are experiencing a condition of fragility caused by both insufficient maintenance activities and the risk factors to which the territory is exposed due to its position and natural conformation. The likelihood of threats is high, and the vulnerability of the territory and built environment is also high. Mapping the territory and conducting control and verification activities are more necessary than ever to contain and mitigate the risks to which assets and people are exposed.

Risk management has taken on emergency proportions in recent decades due to the impact of climate change, exposing cities and neighboring territories to the consequences of extreme weather events that severely test the safety of infrastructure and the lives of people living in particularly vulnerable areas.

This brief introduction immediately highlights the importance of conducting ongoing monitoring activities to assess settlements, displacements, deformations, movements, and subsidence.

What is the purpose of topographic monitoring?

Topographic monitoring allows for measuring the extent of change over time in structures and the territory, as well as monitoring the risks associated with movements and deformations. In this sense, topographic measurements of angles, distances, and level differences can be very useful in determining the variation in the position of a point in space.

In this article, we wanted to delve into an area of topographic instrument usage that has gained significant relevance due to the fragility of our territory and infrastructure. We have also seen how topographic monitoring, which involves repeated geometric measurements over time, enables the control of potentially dangerous movements and deformations.
