EO based monitoring of transport infrastructure in the Czech Republic

Gisat has successfully implemented the development project focusing on introduction of InSAR services to support monitoring of risk phenomena in the transportation domain.

In the frame of this research project Gisat has introduced the methodology aiming at provision of common framework for selection of interferometric data and methods in support of subsidence and deformation risk monitoring within the transportation sector by means of persistent scatterers interferometry.

Movements due to slope instabilities or undermining, deformation of bridges as well as applicability of installation of artificial corner reflectors were covered. The project presents InSAR methods and data, their feasibility, precision and interpretability as well as cost of the solution to responsible authorities in the Czech Republic.

A couple of demonstrational use cases have been carried out utilizing time series of both newly acquired very high resolution commercial SAR data and archive high resolution data from ENVISAT ASAR. The later shall demonstrate the potential of Sentinel-1 imagery for future applications. Utilization of advanced EO based technology for deformation monitoring should supplement traditional geodetic or inclinometric detection methods.

Development of sustainable services based on InSAR shall provide temporally-rich information and cost-effective tools supporting early detection of potential risks and threads related to operation of transportation infrastructure in the Czech Republic.

This project has been funded through the BETA programme of public procurement in research, experimental development and innovation for the government run by the Technology Agency of the Czech Republic.

Gisat provides wide range of geoinformation services based on Earth Observation technology. It focuses on operational application of satellite mapping to monitor various aspects of our environment and development of dedicated web based platforms for geoinformation analysis and assessment Web // E-mail // Tel:+420 271741935 // Fax: +420 271741936
