Data qualification

According to the law, what is a Surveyor ?

The chartered surveyor “carries out topographical studies and work to establish the boundaries of landed property and, as such, draws up topographical plans and documents, at any scale and in any form, concerning the definition of rights attached to landed property, such as plans for the division, sharing, sale and exchange of landed property, plans for the demarcation or demarcation of landed property…”. Article 1° of the law of May 7 1946.

The mission entrusted to the surveyor, and the responsibility that goes with it, require irreproachable quality in the geographic data produced, as well as a thorough understanding of the process by which it is created.
It is crucial that the measurements carried out in the field by surveyors are not only precise, but also accurate.

The evolution of surveying technologies now enables us to announce accuracy of the order of a few centimetres under optimum conditions. However, it is important to note that environmental, human and technical factors can affect the quality of the measurement, without the surveyor necessarily being informed, even though he or she may be held responsible.

So, in some cases, the equipment may be accurate or even very accurate, but the measurements may be incorrect…

In this context, TERIA has initiated a profound reflection on the qualification of geographic data and how to guarantee levels of precision and accuracy during field operations.
During two workshops, Paul Chambon, General Manager and Head of TERIA’s Technical Department, presented the automatic control methods that could be configured by the surveyor according to accuracy class. These advances could protect surveyors in case of anomalies.

A not so ordinary Annual General Meeting

EXAGONE TERIA’s traditional Annual General Meeting took place alongside the Summer Universities in Le Mans. It was an opportunity to report on the year’s achievements and present the latest news. Important announcements were made at the meeting, explaining the very special nature of the event.

After 30 years of dedicated work at EXAGONE TERIA, Jean BERTERRECHE has decided to retire.

He has been succeeded by Patrick DI RENZO, formerly General Manager, and Paul CHAMBON, who now holds the position of Managing Director.

Patrick DI RENZO

It’s a great honor for me to take on the role of Chairman of EXAGONE TERIA. I will carry out this new role with enthusiasm and passion, but also with humility and determination.
In this year of Olympic preparations, I’d like to quote Pierre de Coubertin’s motto: “Faster, higher, stronger, together” – yes, together! Because you are our raison d’être, and I’m counting on you to support me during my term of office.
Thanks to the progress we have made since 2005 and the numerous projects that have come to life within TERIA, our teams can be proud of the work they have accomplished to develop our Company and give it its current base.
I am very confident in our ability to pursue this managerial policy and to take advantage of new prospects to place TERIA among the leaders in the precision geolocation sector.

I would like to thank our shareholders for their confidence.
We will continue to develop TERIA’s project by extending the panel of users and by continuing, together with all our staff and stakeholders, to work for a responsible growth and sustainable development.

Executive Director

The ceremony ended with a warm round of applause and a lot of emotion. After these rich revelations, the TERIA team invited customers and partners to their stand for a “verre de l’amitié“, to celebrate the news in a warm and friendly atmosphere.
