Master class on total station measurements at IcGSMWerner Lienhart gave a master class on total station measurements at the 5th International Course on Geotechnical and Structural Monitoring (IcGSM) in Rome. In this interactive tutorial potential error sources of total station based monitoring were discussed and the participants had the chance to experience the impact of wrong instrument settings or insufficient equipment in hands on experiments.
Visitor Record at Long Night of Research 2018The Long Night of Research had a new visitor record of 228 000 people visiting exhibitions at Austria’s research institutes. TU Graz was strongly involved with 30 exhibition areas. IGMS demonstrated "How to digitize the whole world" using laser scanners, tracking total stations and mobile mapping systems.
Research visit from ItalyPaolo Caporossi, PhD student at the University of Rome Sapienza, joins IGMS for a 2 months research visit. Paolo focusses in his research on the development of imaged based methods for monitoring of natural hazards. During his stay in Graz, Paolo will evaluate his methods in the IGMS measurement lab. Additionally his methods will be used with other monitoring techniques of IGMS to observe the behavior of a rock face in Austria. We welcome Paolo and wish him a fruitful stay in Graz.
Distributed Fiber Optic Installation at Semmering Base TunnelIGMS successfully performed a second distributed fiber optic installation in the shotcrete lining at the Semmering Base Tunnel. Permanent Brillouin and Rayleigh measurements are used to assess the deformation behavior at the early stage right after excavation. Periodic long term measurements will be used to assess the long term behavior of the tunnel. More about the fiber optic activities of IGMS in tunneling can be found here.
Christoph Monsberger receives Heinrich Wild Award 2017Christoph Monsberger received the Heinrich Wild Award 2017. The Heinrich Wild Award recognizes outstanding young researches in the field of Engineering Geodesy. This prize is awarded by Leica Geosystems AG and Christoph Monsberger was selected as winner for the development of innovative solutions for monitoring of tunnel linings based on distributed fiber optic sensing.
Invited Talk of SLACGeorg Gassner, Department Head for Metrology at the SLAC National Accelerator Laboratory operated by Stanford University for the U.S. Department of Energy, visited IGMS and gave an invited talk on “Alignment activities at the SLAC National Accelerator Laboratory”.
Dipl.-Ing. Matthias Ehrhart successfully defended his PhD Thesis with the title “Applications of image-assisted total stations: Concepts, experiments, results and calibration”. This thesis is available at the Shaker Verlag. The examiners Prof. Thomas Wunderlich from TU Munich and Prof. Werner Lienhart from TU Graz congratulate Dr. Ehrhart on his new doctor title.
Geoday 2017On November 27th IGMS co‐hosted the 5th Geoday– the open house presentation of the Geodesy and Geomatics Science courses at TU Graz. Several school classes from different Austrian counties experienced hands‐on demonstrations and exciting presentations of the wide range of geodetic applications. More information about this event can be found at http://geoday.tugraz.at/.
KinderUniGraz visits IGMSOn September 25th, KinderUniGraz visited IGMS. Pupils from a 4th grade elementary school (Volksschule Premstätten) learned about the principles of surveying and went on a treasure hunt with total stations.
Fibre optic measurements of ferryboatIGMS performed in collaboration with Fróðskaparsetur Føroya (The University of the Faroe Islands) and the University of Nottingham Ningbo (China), fibre optic deformation measurements of a ferryboat. High frequent strain data of the ship's hull were recorded during the loading and unloading of the ship and while the ship was sailing on the sea. The high-resolution data are expected to provide new insights into the ship's behavior.
3D Modelling of a Stalactite CaveIGMS bachelor students performed terrestrial laser scanner measurements in the stalactite cave Katerloch. The Katerloch is one of the largest stalactite caves in Austria. Goal of the measurements are the development of a 3D model of the cave, which can be used to determine the dimensions of the cave. Furthermore, the number and size of the stalactites as well as 2D plans shall be derived from the 3D model.
18th International Course on Engineering Geodesy held at TU GrazThe 18th International Course on Engineering Geodesy was held at TU Graz from April 25th until April 29th. TU Graz, ETH Zurich and TU Munich jointly organized this prestigious conference. More than 300 experts attended the tutorials with practical exercises, the presentations or joined the excursion. The program and impressions from the course can be found at iv2017.tugraz.at.
IGMS Professor Fritz K. Brunner explains the challenges of accurate GNSS positioning in the new video of Leica Geosystems AG. In this video the crucial elements of reliable positioning with cm accuracy are highlighted. These are: 1) Reception of the analogue signals with excellent multipath mitigation and stable phase centre for all signals. 2) AD conversion with minimum noise but still high sensitivity for tracking under canopy. 3) Smart algorithms to fix and validate phase ambiguities. The full video is available on YouTube.
