The planning, design and management of infrastructures require a in-depth knowledge of the territory and its dynamics.
It is essential to have updated information regarding the risk of landslides, their localization, delimitation and speed to plan and manage new infrastructural networks (motorways, railways dams and industrial sites).
Preciso® landslide is a service of territorial mapping designed for the monitoring of large infrastructures, which supplies detailed information on:
- Localization of areas at risk
- Degree of landslide activity
Applications
- Timely identification of subsidence phenomena
- Optimization of monitoring in situ
- Planning emergency maintenance intervention
Target
- Infrastructure and works managers and builders
Benefits
- Updated knowledge of ground conditions
- Continuous monitoring of landslide areas
- Limited cost of service management
- Safeguarding of investments

Technical Characteristics
Preciso® landslide uses readings taken from Synthethic Aperture Radar (SAR) data to measure sub-centimetric movements of reference points on the ground.
The ample availability radar satellites, such as Cosmo-SkyMed, ERS, Envisat, Radarsat and Terrasar-X give the possibility of frequent readings, allowing continuous territorial monitoring in any area of the globe, with historical data cover the last ten years.
The maps of movement are used as database to classify the state of the landslide.
The service also uses optical stereoscopic images to define the areas of subsidence.
Informative content
Preciso® landslide provides periodical supply of a geographical database containing polygons of the landslide areas, associated with the information on condition and the trend of movement in recent years.
The frequency of information updating is based on the users’ needs.
In areas where the perimeters of the landslides are unknown, the activation phase of the service includes new mapping or updating of landslide charts.
Preciso® landslide was designed in collaboration with the experts from CNR IRPI of Perugia, Italy, specialized in satellite data processing and geomorphological interpretation. The extraction of interpherometric measurements of the movement of reference points on the ground taken from SAR (Synthetic Radar Aperture) satellite data is made with the SPINUA algorithm created by GAP Srl, a spin-off the Politecnico of Bari.
