RASTOOL proposes a set of tools which are targeting the preparedness against ground motion phenomena detectable by means of satellite interferometry. The outputs are intended for the use within the CP cycle, specifically in the preparedness and prevention stages.
2G-ADAtools
The job of this tools is to derive the so-called Active Deformation Areas (ADA), in other words the areas that record high ground motion rates. The ADA are a way to simplify the interpretation of the interferometric data and they allow the user to focus on specific areas without having to analyse millions of measurement points.
The tools are adapted to work with the enormous data volume of the EGMS and can read the EGMS data without any further action of the user. The tools are available to users though a user friendly frontend.
ADA Classifier tool
This tool aims to classify the detected ADAs based on the triggering deformation process that causes the active ground movement according to different detectable phenomena (i.e., landslides, sinkholes, subsidence, embankments, etc.).
The tool has a module that informs about the temporal evolution of the phenomena (TS classifier). The module automatically analyses the time series of deformation through a series of statistical tests that allow the identification of distinctive trends.
ADA-Impact tools
These tools rely on the outputs of the ADA Classifier to provide the potential impact assessment of the detected active deformation areas. The idea is to use the outputs of the ADA Classifier together with updated data on exposure and vulnerability.
These tools allow combining hazard, exposure and vulnerability, and quantifying risk to support decision making.
RASTOOL will test and demonstrate the use of the tools at two different scales. First, on the Portuguese-Spanish border with the goal to reach the best performances. Secondly, the tools will be applied along the borders between some of the members of the geological surveys part of Eurogeosurveys. The pilot areas will be selected considering the priorities of the geological surveys involved in the project.
