Working Group 6.1 - Deformation Measurements and Analysis
Policy Issues
Deformation studies in Engineering Surveying are based on a broad knowledge
of suitable sensors and their potential, modern data storage and communication
solutions and advanced processing and analysis methods. Additionally a thorough
understanding of the behaviour of monitoring objects (large scale structure or
landslide effected area), is essential to set-up and operate an optimum
monitoring system. Nowadays deformation tasks are more and more oriented towards
real-time systems, which require automation of data capture and new concepts in
data processing, analysis and interpretation.
WG6.1’s main goals will be to support specialists in deformation studies with
state-of-the art solutions and provide latest developments and future oriented
concepts:
- Promoting studies on the potential of existing and new sensors to
determine geometric deformation quantities from surveying and adjacent
fields such as geotechnics;
- Promoting the development of concepts for automated data storage, data
transfer and data pre-processing;
- Promoting the adaptation of numerical algorithms to derive relevant
deformation quantities in real-time, including concepts from time series
analysis;
- Promoting a multidisciplinary collaboration between surveying,
structural and geotechnical engineers to understand the behaviour of
structures and geotechnical objects;
- Study of most modern concepts for data analysis like artificial neural
networks, fuzzy logics and generic algorithms;
- Initiate investigations to extend the range of deformation studies to
higher frequencies, which are important in Structural Health Monitoring,
i.e. to be able to study oscillations and vibrations and their effects on
critical structures;

Working Group 6.2 - Engineering Surveys for Construction Works
and Structural Engineering
Policy issues
- Promoting the use of adapted survey techniques in industry &
engineering;
- Promoting a multidisciplinary collaboration between survey engineers,
civil engineers, structural & mechanical engineers;
- Promoting the use of adapted survey techniques in the rail and railway
building and operating sector;
- Promoting the understanding of fibre optic sensors, e.g. interferometric
sensors, Brillouin and Raman scattering and Bragg gratings;
- Study the use of embedded sensor arrays and the role of advanced
surveying techniques for structural monitoring;
- Creating an awareness of surveyors through a task force “Fibre optic
sensors” of the rapidly emerging technology of fibre optic sensors as
"non-geodetic" sensors to measure deformations (strain) and temperatures in
civil engineering structures
- Promoting the use of Terrestrial based RF positioning system in
engineering surveying;
- Creating an awareness of surveyors through a task force “Geotechnical
sensors” as the trend today is going for an integration of those sensors in
the geodetic deformation analysis.
- Creating an awareness of surveyors through a task force “Railways
Trolley monitoring system.

Working Group 6.3 - Machine Control and Guidance (MCG)
Policy issues
The importance of real-time 3D-position sensors for navigation of machinery
on construction sites of roads, tunnels, railways, and airports has increased
over the last years and the market is still growing. Also in the field of
agriculture GPS-based applications such as crop mapping and automatic steering
are well introduced. The new FIG Working Group 6.5 will intensively deal with
following topics:
- Kinematic Measurement and Sensor Technology (focus on L1 RTK Cow-cost
systems, adjustments of total station MCG requirements, additional Sensor
like Slope Sensors, INS, Orientations Sensors, etc.)
- 3D-Applications (Agriculture, Construction, Special Applications e.g.
UAVs),
- Multi-Sensor Systems and -platforms
- MCG Data Processing and Data Flow
- Control Process and Control Algorithm
- Standardization of Major Construction Projects
The main goal of Working Group 6.3 is the interaction of research and
industry activities.
