Surveying technology and equipment
The right instrument depends on the accuracy you need and on the site. Here is the equipment we own and use on our projects.
Equipment
Our equipment
An earthworks site, a listed facade and a utility network several
kilometres long call for neither the same instrument nor the same
accuracy. Our fleet covers every scale of capture, from the
millimetre on a detail to the square kilometre flown in a
morning.
The instrument is chosen before we go on site:
accuracy required, area to cover, access, satellite reception,
deadline. It is this fit to the real constraints of the site that
determines the quality of the result, far more than any
instrument's data sheet.

3D digitisation by drone: from field survey to BIM model
This video was filmed during the L'Industreet training, a 12-day programme on 3D data acquisition and BIM modelling. It shows the equipment GEOREVO uses every day on building sites and existing buildings across Switzerland: a drone for photogrammetry, a laser scanner for interiors and fine detail, and point clouds for modelling.
Drone and photogrammetry
The drone flies the site along a prepared flight plan (overlap, ground resolution). It produces orthophotos and point clouds that can be used for earthworks, roofs and facades. See our aerial photogrammetry service.
3D laser scanner
Inside a building or on a fine detail, the laser scanner records millions of points. The scans are then registered, structured and checked before delivery. See our 3D laser scanning service.
Point cloud to BIM
Point clouds are modelled (architectural, structural and technical packages) and coordinated to deliver a model that is true to the existing building. See our BIM modelling service.
Frequently asked questions about drone and scanner surveys
Why combine a drone and a laser scanner?
The drone quickly covers large areas and high parts (roofs, terrain, facades), while the laser scanner adds detail indoors and on nearby elements. Together they give a single consistent dataset, from the site to the building.
What do you receive after a 3D survey?
Depending on the project: orthophotos, point clouds, a 3D model or a BIM model. Every deliverable goes through a quality check before it is handed over.
Where does GEOREVO work?
From our geomatics office in Lausanne, we work throughout Switzerland for architects, developers, engineering firms and municipalities.
Security & performance
Secure, reliable infrastructure
Secure servers
Data hosted in Switzerland on protected infrastructure, keeping sensitive information confidential and secure.
Regular backups
Frequent backups of databases and mapping systems, so recovery is quick when needed.
Performance tuning
Fast response times even on limited connections, through compression and caching.
