Fibre optic measurements of ferryboat

IGMS 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 Cave

IGMS 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 Graz

The 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 presents project SIBS at VÖBU fair

IGMS presented first results of the research project SIBS at the VÖBU fair in Vienna. The project SIBS focuses on the automated remote detection of damages of retaining walls along motorways and railway tracks. IGMS records mobile mapping data using a platform with 2 laser scanners, 1 IMU, 6 cameras and 1 differential GNSS receiver. The resulting high-resolution point clouds are analyzed automatically with newly developed algorithms. More information about the project can be found at the VÖBU Blog.


IGMS interview on radio station

Werner Lienhart explains the benefits and challenges of Structural Health Monitoring (SHM) in a radio interview. The research work of IGMS in this field supports predictive maintenance and provides early warnings in case of structural failure. The interview was broadcast on the webradio of TU Graz and on Radio Soundportal.

Field Trip Tunnel Stein

 On January 13th, IGMS organized a field trip to the construction site of the Tunnel Stein for the students of Engineering Geodesy. The Tunnel Stein is part of the Koralmbahn which, after completion, will reduce the travel time from Graz to Klagenfurt from 2 hours to 45 minutes.

Ingenieurvermessung 2017

The program for the International Course on Engineering Geodesy IV2017 is new online and registration has been started. Reduced prices are available until 31.01.2017!

Geoday 2016

On November 25th IGMS co‐hosted the 4thGeoday – the open house presentation of the Geomatics Engineering 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.

IGMS Monitoring Project on Austrian TV Show

The patented IGMS monitoring solution (AT516158 B1) for tunnel segment linings is featured in the science magazine Newton of the Austrian TV channel ORF EINS. The embedded distributed fibre optic measurements deliver the complete strain field inside the tunnel segments and can be used to determine stresses within the segment. An optimization of the segment design is possible based on the fibre optic measurements during detailed investigations on a tunnel segment test rig.

KinderUniGraz visits IGMS

On September 26th, KinderUniGraz visited IGMS. Pupils from a 3rd grade elementary school (Volksschule Gralla) gained hands-on experience with modern geodetic measurement systems.

IV 2017 - Call for Abstracts opens

Abstracts can now be submitted to the 18th International Course on Engineering Geodesy (Internationaler Ingenieurvermessungskurs) which takes place at Graz University of Technology from 25. to 29. April 2017. This course is jointly organized by ETH Zurich, TU Munich and TU Graz. Deadline for abstract submission is 17.10.2016. More information is available at iv2017.tugraz.at.

Best Paper Award at ICSIC

IGMS and its co-authors won the best paper award at the International Conference on Smart Infrastructure and Construction (ICSIC) held at the University of Cambridge. Werner Lienhart received the award from Professor Lord Mair at the conference dinner at St. Johns College. The awarded paper Condition monitoring of railway tracks and vehicles using fibre optic sensing techniques is based on the IGMS research in a railway monitoring project.

Guest lecturer em. Prof. Brian Culshaw finalizes his visit at IGMS

After two weeks staying at Graz University of Technology Brian Culshaw gives his final lecture and discusses the challenges of fiber optic sensing with students. Thank you Brian for visiting IGMS and the exchange of research ideas.

IGMS Master Students visit tunnel construction sites

IGMS students visit the tunnel construction sites Fröschnitzgraben, Longsgraben and Grautschenhof of the Semmering Train Tunnel. At Fröschnitzgraben two 400m deep shafts are being constructed for an intermediate tunnel access. The disposal site of this and other construction sites is located at Longsgraben where IGMS operates the long term fiber optic monitoring of a reinforced earth structure. Another intermediate access is located at Grautschenhof where a gas pipeline has to be permanently monitoring in order to detect deformations caused by tunnel construction.

Em. Prof. Brian Culshaw gives a guest lecture at TU Graz

Brain Culshaw, emeritus Professor of University of Strathclyde Glasgow, stays for two weeks in Graz to give a guest lecture on Enhanced (fiber optic) Sensing and Monitoring. Brian is a renowned researcher of fiber optic sensors, published several books in this field, founded sensor companies and initiated leading fiber optic conferences. During his stay students will get an insight view of fiber optic sensors and also see fiber optic sensing in action during an excursion to the monitoring site Longsgraben.

Month of Open Education

As part of the project Month of Open Education, the lecture Surveying was held at the urban public park of Graz. The students and park visitors enjoyed the relaxed atmosphere while learning the principles of different distance measurement techniques.

Matthias Ehrhart receives Heinrich Wild Award 2015

Matthias Ehrhart has been awarded the Heinrich Wild Award 2015 on January 20th. The Heinrich Wild Award recognizes outstanding young researches in the field of Engineering Geodesy. This prize is awarded by Leica Geosystems Austria GmbH and Matthias Ehrhart was selected as winner for his innovative work in structural monitoring using imaging total stations.

Field Trip to the Tunnel Chain Granitztal

On January 22nd IGMS organized a field trip to the construction site of the Granitztal Tunnels for the students of Engineering Geodesy. The tunnel chain consists of three tunnels. Two tunnels are constructed with the New Austrian Tunnelling Method (NATM) and third tunnel is an open construction site. During the excursion, the students gained insights into the challenges of geotechnical monitoring and tunnel steering.
