PHOTOGRAMMETRY
Photographs to monitor your structures •
•
Aerial photogrammetry allows the generation of georeferenced point clouds from photographs acquired from a drone. The operation is based on a strong overlap between the different shots. Our drone is equipped with a very high resolution photogrammetric camera that can take pictures pointing towards the nadir or the zenith. This allows us to reach millimeter precision in the position of points in various configurations.
•
The drone can cover very large areas and can fly in rough areas or at altitude.
•
The flight plan is fully automated to ensure productivity and time savings. This allows to plan in advance the customer's expectations and the quality of the desired renderings.
•
Different renderings can be derived from these point clouds being useful for different applications. Our photogrammetric surveys can also be used on land for more restricted applications or when flying is not possible.
•
Photogrammetry can also be used to complete visual inspections, especially in hard-to-reach areas.

3D SCAN / LASERGRAMMETRY
Geospatial acquisition and data processing system •
•
•
•
Terrestrial lasergrammetry is a fast and automatic 3D data acquisition technique, using laser light, to measure the 3D coordinates of points on surfaces from a static terrestrial position and without direct contact with the object of interest. The main difference compared to classical topography is that the object is surveyed as a whole and not only its characteristic points. The raw data is a cloud of points from which a 3D model is derived after processing. The latter allows us to reach a better resolution. This technique is mainly used for the knowledge of the geometry of the installations, their follow-up and maintenance, as well as their archiving in 3D. It is also used in BIM projects that provide architecture, engineering and construction (AEC) professionals with the information and tools needed to more effectively plan, design, construct and manage buildings and infrastructure.

•
•
The NodeLog is a 4-channel analog LoraWAN datalogger designed for infrastructure monitoring, including its ability to interface with potentiometric, 4-20 mA, PT 100 or 05 V sensors, for a complete wireless monitoring solution. The NodeLog is a completely autonomous solution, which can be installed in harsh environments. Its very low power consumption is particularly suitable for long-term monitoring. It can send all its data wirelessly over very long distances using LoRaWAN technology and can be reconfigured remotely.

DELTAINSAR®: MEASUREMENTS BY RADAR SATELLITES A method of measurement via satellites •
•
• •
DeltaINSAR is a Radar satellite monitoring system. It allows the measurement of horizontal and vertical displacements of large structures and the surface of the environment with millimeter accuracy and a high density of measurement points. DeltaINSAR can be set up without any prior insitu installation. This is of great interest when the monitored area is inaccessible or unsuitable for ground-based instrumentation. If necessary, the density of the measurement points can be increased by installing artificial radar reflectors called Corner Reflector (CR). Our solution allows for continuous and regular monitoring of deformation that occurs before, during and after construction projects, underground operations or unstable areas.

TEMPERATURE SENSOR PT 100 : TEMPERATURE SENSOR Suitable for all temperature measurements •
The PT100 temperature sensor from SOCOTEC Monitoring allows temperature measurement in free air, on the surface of a structure or in concrete.
•
They are highly reliable sensors, widely used in all industries. A PT100 is a resistive probe, whose electrical resistance depends on the temperature.
•
If the cable used is standard, the maximum temperature will be 80°C, but it is possible to change the cable for temperatures ranging from -200°C to 650°C.
