i2MON - Geomonitoring

Within the framework of the research project i²MON - "Integrated Impact MONitoring for the detection of
ground and surface displacements caused by coal mining" funded by HORIZON 2020 through the RFCS
(Research Fund for Coal and Steel), the authors in cooperation with various European institutions are
concerned with the development of an integrated monitoring service for the identification and evaluation
of ground and slope movements in connection with coal mining. The focus is on the correct integration of a
long range laser scanner into a continuous web-based monitoring system from an engineering geodetic
point of view. The knowledge thus derived can also be transferred to other applications such as the
monitoring of mass movements in general. Current research topics deal with the reliability, accuracy and
integrity of 3D point clouds in a monitoring system.
In this paper, the authors present test installations of long range laser scanners in permanent operation and
limiting factors to the LIDAR technology. It is shown how the laser scanner can be controlled remotely within
a web-based monitoring platform. In addition, the integration of different sensors into a unique monitoring
platform bases on a web interface and is presented. Keywords: LIDAR, Multi-temporal 3D Point Cloud
