Seafloor characterization using airborne hyperspectral co-registration procedures independent from attitude and positioning sensors

The advance of remote-sensing technology and data-storage capabilities has progressed in the last decade to commercial multi-sensor data collection. There is a constant need to characterize, quantify and monitor the coastal areas for habitat research and coastal management. In this paper, we present work on seafloor characterization that uses hyperspectral imagery (HSI). The HSI data allows the operator to extend seafloor characterization from multibeam backscatter towards land and thus creates a seamless ocean-to-land characterization of the littoral zone

MusA: Using Indoor Positioning and Navigation to Enhance Cultural Experiences in a museum

In recent years there has been a growing interest into the use of multimedia mobile guides in museum environments. Mobile devices have the capabilities to detect the user context and to provide pieces of information suitable to help visitors discovering and following the logical and emotional connections that develop during the visit. In this scenario, location based services (LBS) currently represent an asset, and the choice of the technology to determine users' position, combined with the definition of methods that can effectively convey information, become key issues in the design process. In this work, we present MusA (Museum Assistant), a general framework for the development of multimedia interactive guides for mobile devices. Its main feature is a vision-based indoor positioning system that allows the provision of several LBS, from way-finding to the contextualized communication of cultural contents, aimed at providing a meaningful exploration of exhibits according to visitors' personal interest and curiosity. Starting from the thorough description of the system architecture, the article presents the implementation of two mobile guides, developed to respectively address adults and children, and discusses the evaluation of the user experience and the visitors' appreciation of these application

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

A LOCAL SPATIAL DATA INFRASTRUCTURE TO SUPPORT THE MERAPI VOLCANIC RISK MANAGEMENT: A CASE STUDY AT SLEMAN REGENCY, INDONESIA

This research aims to implement an application of a Local Spatial DataInfrastructure (SDI) for evacuation planning of Merapi Volcano disaster. Theprocesses, problems and information flows in evacuation planning were examined.Geo-collaboration Portal was customized in order to provide spatial resources fordecision makers. It is equipped with usable maps presentation and interaction toolsto support collaborative decisions. User group assessment was carried out toevaluate usability of the application. The evaluation results showed thatcollaborative portals on top of a local SDI can facilitate effective decision makingprocess and improve coordination among involved stakeholders in thecontext of disaster preparedness and mitigation. Several aspects need to beconsidered in order to achieve a functional local SDI e.g. availability and qualityof the spatial data, establishment of local regulations and standards, developmentof metadata, and strengthening capable human resources

Mobile GIS: The Development of Spatial Analysis Tools in an Integrated Environment for Emergency Responders

Bringing GIS to the field has many limitations to the end user due to currently available mobile computing and connectivity shortcomings. Of major concern is the lack of spatial analysis and querying abilities currently available in commercial off-the-shelf (COTS) software for mobile applications. Current mobile GIS offers mapping and visualization capabilities, while providing no analytical means to discover the data spatially. Adding spatially-based analysis tools will enable emergency responders to more accurately record the state of a particular area and better understand their surroundings while collecting important field assessments. This allows for more timely and accurate assessments by emergency planners to better allocate resources in the field. This paper outlines the development of both connected or server run, and disconnected analysis tools for emergency responders in a mobile framework. The proposed tools were developed with ESRI‟s ArcGIS Server Mobile Software Development Kit utilizing server technology. They leverage the mobile application based data and internet-based services to perform these tasks. This project is focused on the development, and subsequent inclusion into, an enterprise emergency response system: PREACT

VATDIS Web Mapping - A Report on the Application of Open Standards and Open Architecture in Geospatial Interoperability for Emergency Management

This report provides an overview of the web mapping activities carried out in the VATDIS action in 2007. These web mapping activities aimed at integrating the work done for the Orchestra, Floodsite and Preview IP into one single demonstrator. In the main section of this report an outline is given of the reasons for integrating the projects and the contents of this integration. The report should be seen as a summary of the technical choices made in order to accomplish this integration. The annexes on this report help the more technical reader to understand the design of the demonstrator and to duplicate it for its own purposes.JRC.G.7-Traceability and vulnerability assessmen
