Die permanente dreidimensionale Datenerfassung geotechnischer Strukturen mittels webbasierter Anwendung terrestrischer LiDAR‐Sensorik

Abstract

As part of the i2MON research project, an integrated monitoring service was developed for the identification and evaluation of soil and slope movements in the context of coal mining. The focus was on the correct integration (to give reliability, accuracy and integrity) of a long‐range laser scanner into a web‐based monitoring system from an engineering geodetic point of view. A web‐based application of terrestrial laser scanners has been developed by cooperation between DMT GmbH & Co. KG and RIEGL Laser Measurement Systems GmbH. The system allows a high temporal and spatial resolution for measured value acquisition by means of permanent installation in the vicinity of a monitored object. This article shows how the laser scanner can be remotely controlled within a web‐based monitoring platform. In addition, the integration of various sensors (including total station, GNSS, geotechnical sensors) within a project into a uniform monitoring platform based on a web interface and the corresponding data analysis (including the automatic detection of geomorphological processes) will be described.
