Geodetic monitoring defined as the systematic measurement and monitoring of changes in the shape or dimensions of objects or surfaces as a result of forces applied to them.
Geodetic monitoring due to its relatively low cost comparing to other methods, is widely spread and used in all projects.
Conventional Geodetic Monitoring
Leveling measurements of preinstalled pins on buildings, structures, pavements, deep points, embankments, using high accuracy digital levels and invar stuffs.
3D optical targets
Three dimensional displacement measurements on bi-reflex targets or monitoring prisms, that are installed in tunnels, on structures, buildings etc., using high end total stations.
To achieve semi automatic measurements and to maximize their accuracy but also to minimize the field time, an in-house software is developed. Terramon field software can be installed in tablet, laptop, pc and Terramove Control Box of the Automatic Monitoring System (A.M.S.)
Automatic Monitoring system (AMS)
Modern project’s safety requires 24/7, high frequency and accurate measuring monitoring systems.
Encardio-Moniterra Group uses an in-house developed system that consists of a series of networked robotic total stations, each one controlled by the Terramon Software, installed in the dedicated Terramove Control Box.
This system ensures valuable and timely monitoring of the displacements, providing high measurements density, simultaneous wireless transmission and automatic entry of the results in to the Terramove Monitoring Data Base.
The system can be accessed and controlled remotely from anywhere by the users.
It is a method based on exceptionally dense mapping of three dimensional coordinates of the points on the surface to be monitored.
Laser scanning is a rapid and reliable surveying method, collecting data in Static, Stop & Go or Kinematic mode.
From the point cloud produced , the exported section profiles can be used to monitor deformations or displacements mainly in tunnels, but also on other structures or landslide and rock fall areas, glaciers, etc.
Monitoring using UAVs
A rapid and safe way of collecting data for large scale areas, like deserts, mountains or glaciers, where millimeter accuracy is not necessary, but motion of mass is vital to be determined.
Unmanned and remotely piloted aircrafts follow a preprogrammed flight path. Equipped with HD/IR/Thermal cameras they capture aerial images, over a defined area.
The point clouds, meshes and 3D models produced are the data to be compared between sequel flights during monitoring time.
Rail Monitoring system
To-the-millimeter accuracy is vital during track operation. Owners, supervisors and operators of high-speed rail links naturally count on reliable surveying technologies to monitor the impact of the huge forces of traffic or construction activities on the rails.
For the purposes of measuring accurately the rail tracks, a proper device should be used. Amberg’s GRP FX trolley system is equipped with high-end technology sensors to record Cant, Gauge and Odometer. It is getting and correcting its position using the control points with an on board total station or disto-meter and an integrated IMU sensor.
Analysis of the recorded inner and outer track geometry, follows in dedicated software, so that, evaluation, conclusions and actions to be taken.
