Rapid developments in engineering, microelectronics and the computer sciences have greatly changed both instrumentation and methodology in engineering geodesy. To build higher and longer, on the other hand, have been key challenges for engineers and scientists since ancient times. Now, and for the foreseeable future, engineers confront the limits of size, not merely to set records, but to meet the real needs of society minimising negative environmental impact. Highly developed engineering geodesy techniques are needed to meet these challenges. The SC will therefore endeavour to coordinate research and other activities that address the broad areas of the theory and applications of engineering geodesy tools. The tools range from conventional terrestrial measurement and alignment technology (optical, RF, etc.), Global Navigation Satellite Systems (GNSS), geotechnical instrumentation, to software systems such as GIS, decision support systems, etc. The applications range from construction engineering and structural monitoring, to natural phenomena such as landslides and ground subsidence that have a local effect on structures and community infrastructure. The SC will carry out its work in close cooperation with other IAG Entities, as well as via linkages with relevant scientific and professional organisations such as ISPRS, FIG, IEEE, ION.

Objectives

To monitor research and development into new technologies that are applicable to the general field of “engineering geodesy”, including hardware, software and analysis techniques.
To study advances in dynamic monitoring and data evaluation systems for buldings and other manmade structures.
To study advances in monitoring and alert systems for local geodynamic processes, such as landslides, ground subsidence, etc.
To study advances in geodetic methods used on large construction sites.
To study advances in the application of artificial intelligence techniques in engineering geodesy.
To document the body of knowledge in this field, and to present this knowledge in a consistent frame work at symposia and workshops.
To promote research into several new technology areas or applications through the SC4.2 Working Groups.

Program of Activities

To study the technology and applications of engineering geodesy in order to address the objectives for SC4.2 (see above).
To organize and to participate in professional workshops, seminars, meetings, etc.
To establish a web page providing information on SC4.2 activities, professional meeting calendar, etc.

WG 4.2.4: Investigation of Kinematic and Dynamic Behaviour of Landslides and System Analysis

Chair:	Gyula Mentes (Geodetic and Geophysical Research Institute of HAS, Hungary)
Co-Chair:	Paraskevas Savvaidis (University of Thessaloniki, Greece)

Terms of Reference: Worldwide landslides are one of the major types of natural hazards killing or injuring a large number of individuals and creating very high costs every year. There has already been done a wide range of research work on landslides. Most of this work had a bias towards one discipline, like remote sensing or geology. The new idea of the working group is to promote multidisciplinary integration of different methods. The main goal is to set up an integrated workflow for landslide hazard management.

Objectives

To study advances in dynamic monitoring and data evaluation systems for landslide prone areas.
To study advances in multi-sensor monitoring and alert systems for landslides.
To study the interactions between landslides and geophysical, geological, geomorphological, hydrological, geomechanical, meteorological, etc. processes.
To develop knowledge based systems for landslide risk assessment.
