Public Administrations as well as Assurance Companies need to continuously assess the stability of buildings and critical infrastructures they manage. Human activities and natural phenomena can seriously affect buildings up to their collapse, exposing people to the risk of their life and strategical assets to lose their functionality.
Traditional engineering analysis is very accurate but expensive if applied to a large number of buildings as could be the case of assurances or PA who manages council estate. e-GEOS technologies support Public Administration in monitoring wide areas with lower costs thanks to the COSMO-SkyMed capabilites.
PRELIMINARY IDENTIFICATION OF BUILDINGS AND STRUCTURE
The e-GEOS solutions could be a significant support to manager to address first deeper analysis and evaluate building safety.
The solution is based on the provision of data and services through the use on remote sensing data. In fact, remote sensing imageries allow to monitor wide areas with limited costs. Modern techniques are also able to guarantee high accuracy and high measurements density, mandatory for building stability analysis. Moreover, data derived by remote sensing analysis can be easily integrate and managed through GIS base platforms which allow data cross correlation for deeper analysis and modelling.
- To guarantee safety for population
- To analyse the stability of a large number of buildings
- To save money
Our solution enables the detection of slow movements and structural failures of buildings in their early stage by adopting e-GEOS patented processing technology (PSP-IFSAR©).
The method is based on the analysis of time series of SAR satellite data, allowing to measure displacements with millimetre accuracy. This solution allows to collect displacement measures over points scattered on the territory, with a density that, in urban areas, can exceed 20,000 points per squared kilometre: so, in general, a large amount of measurements for each building.
Measures are fully tri-dimensional and all measures can be managed in any GIS systems. Achievable accuracy in the velocity estimation is continuously tested vs ground measurements.
The PSP-IFSAR© analysis provides both an overall view of an urbanized area stability and also highly detailed (millimetre accuracy) information on single building and structures, without any kind of ground measurements and instrumentation setting up and maintaining.
