We present a case study on the migration to a Cloud Computing environment of the advanced differential synthetic aperture radar interferometry (DInSAR) technique, referred to as Small BAseline Subset (SBAS), which is widely used for the investigation of Earth surface deformation phenomena. In particular, we focus on the SBAS parallel algorithmic solution, namely P-SBAS, that allows the production...
This paper presents the integration of the advanced Differential SAR Interferometry (DInSAR) algorithm referred to as Parallel Small BAseline Subset (P-SBAS) within the ESA's Grid Processing on Demand (G-POD) environment in the framework of ESA Geohazards Exploitation Platform (GEP). The aim of this activity is to set up a scientific service that allows, in unsupervised manner, the generation of SBAS-DInSAR...
The advanced Differential SAR Interferometers (DInSAR) methodologies are widely used for the investigation of Earth's surface deformation phenomena. In particular, the advanced DInSAR approach referred to as Small Baseline Subset (SBAS) technique is able to produce deformation velocity maps and the corresponding displacement time-series from a temporal sequence of space borne SAR acquisitions. Considering...
One of the main open issues in the development of applications for sensor network management is the definition of interoperability mechanisms among the several monitoring systems and heterogeneous data. Interesting researches related to integration techniques have taken place, they are primary based on the adoption of sharing data-mechanisms; furthermore in the last years, the Service-Oriented Architecture...
Nowadays, there is a large diffusion of open and dynamic cooperative architectures that are based on services (SOA). In general, a customer is not only interested in service functionalities, but also in its quality (i.e. performance, cost, reliability, security and so on). In this scenario, models, techniques and tools supporting the effective selection of the service that provides the better quality...
A common approach to formally describe security mechanisms is the definition of proper policies. In many contexts, a system could be considered secure and trustworthy if the policy enforced by its security administrator is trust-worthy as well; within such contexts it is possible to evaluate the system security by evaluating its policy. In a previous paper we have proposed a policy-based methodology,...
In dynamic cooperative architectures that are based on services (SOA), customers are not only interested in service functionalities, but also in their quality, such as performance, cost, reliability, security and so on. In this scenario, models, techniques and tools supporting the selection of the best service are needed. In this paper, we propose an evaluation framework that includes a flexible quality...
Obtaining a measure of the trustability of a system in an open environment is a difficult task since trust concepts involve different quality criteria including non-technological aspects. Quality criteria and, above all, security mechanisms are commonly characterized by means of a set of statements making part of a policy. We are working on an evaluation methodology allowing automatic management for...
