Geoinformatics in Citizen Science

The book features contributions that report original research in the theoretical, technological, and social aspects of geoinformation methods, as applied to supporting citizen science. Specifically, the book focuses on the technological aspects of the field and their application toward the recruitment of volunteers and the collection, management, and analysis of geotagged information to support volunteer involvement in scientific projects. Internationally renowned research groups share research in three areas: First, the key methods of geoinformatics within citizen science initiatives to support scientists in discovering new knowledge in specific application domains or in performing relevant activities, such as reliable geodata filtering, management, analysis, synthesis, sharing, and visualization; second, the critical aspects of citizen science initiatives that call for emerging or novel approaches of geoinformatics to acquire and handle geoinformation; and third, novel geoinformatics research that could serve in support of citizen science

A principled approach to measuring the IoT ecosystem

Internet of Things (IoT) devices combine network connectivity, cheap hardware, and actuation to provide new ways to interface with the world. In spite of this growth, little work has been done to measure the network properties of IoT devices. Such measurements can help to inform systems designers and security researchers of IoT networking behavior in practice to guide future research. Unfortunately, properly measuring the IoT ecosystem is not trivial. Devices may have different capabilities and behaviors, which require both active measurements and passive observation to quantify. Furthermore, the IoT devices that are connected to the public Internet may vary from those connected inside home networks, requiring both an external and internal vantage point to draw measurements from. In this thesis, we demonstrate how IoT measurements drawn from a single vantage point or mesaurement technique lead to a biased view of the network services in the IoT ecosystem. To do this, we conduct several real-world IoT measurements, drawn from both inside and outside home networks using active and passive monitoring. First, we leverage active scanning and passive observation in understanding the Mirai botnet---chiefly, we report on the devices it infected, the command and control infrastructure behind the botnet, and how the malware evolved over time. We then conduct active measurements from inside 16M home networks spanning 83M devices from 11~geographic regions to survey the IoT devices installed around the world. We demonstrate how these measurements can uncover the device types that are most at risk and the vendors who manufacture the weakest devices. We compare our measurements with passive external observation by detecting compromised scanning behavior from smart homes. We find that while passive external observation can drive insight about compromised networks, it offers little by way of concrete device attribution. We next compare our results from active external scanning with active internal scanning and show how relying solely on external scanning for IoT measurements under-reports security important IoT protocols, potentially skewing the services investigated by the security community. Finally, we conduct passive measurements of 275~smart home networks to investigate IoT behavior. We find that IoT device behavior varies by type and devices regularly communicate over a myriad of bespoke ports, in many cases to speak standard protocols (e.g., HTTP). Finally, we observe that devices regularly offer active services (e.g., Telnet, rpcbind) that are rarely, if ever, used in actual communication, demonstrating the need for both active and passive measurements to properly compare device capabilities and behaviors. Our results highlight the need for a confluence of measurement perspectives to comprehensively understand IoT ecosystem. We conclude with recommendations for future measurements of IoT devices as well as directions for the systems and security community informed by our work

Semantic discovery and reuse of business process patterns

Patterns currently play an important role in modern information systems (IS) development and their use has mainly been restricted to the design and implementation phases of the development lifecycle. Given the increasing significance of business modelling in IS development, patterns have the potential of providing a viable solution for promoting reusability of recurrent generalized models in the very early stages of development. As a statement of research-in-progress this paper focuses on business process patterns and proposes an initial methodological framework for the discovery and reuse of business process patterns within the IS development lifecycle. The framework borrows ideas from the domain engineering literature and proposes the use of semantics to drive both the discovery of patterns as well as their reuse

Training of Crisis Mappers and Map Production from Multi-sensor Data: Vernazza Case Study (Cinque Terre National Park, Italy)

This aim of paper is to presents the development of a multidisciplinary project carried out by the cooperation between Politecnico di Torino and ITHACA (Information Technology for Humanitarian Assistance, Cooperation and Action). The goal of the project was the training in geospatial data acquiring and processing for students attending Architecture and Engineering Courses, in order to start up a team of "volunteer mappers". Indeed, the project is aimed to document the environmental and built heritage subject to disaster; the purpose is to improve the capabilities of the actors involved in the activities connected in geospatial data collection, integration and sharing. The proposed area for testing the training activities is the Cinque Terre National Park, registered in the World Heritage List since 1997. The area was affected by flood on the 25th of October 2011. According to other international experiences, the group is expected to be active after emergencies in order to upgrade maps, using data acquired by typical geomatic methods and techniques such as terrestrial and aerial Lidar, close-range and aerial photogrammetry, topographic and GNSS instruments etc.; or by non conventional systems and instruments such us UAV, mobile mapping etc. The ultimate goal is to implement a WebGIS platform to share all the data collected with local authorities and the Civil Protectio
