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

The Exploitation of Data from Remote and Human Sensors for Environment Monitoring in the SMAT Project

In this paper, we outline the functionalities of a system that integrates and controls a fleet of Unmanned Aircraft Vehicles (UAVs). UAVs have a set of payload sensors employed for territorial surveillance, whose outputs are stored in the system and analysed by the data exploitation functions at different levels. In particular, we detail the second level data exploitation function whose aim is to improve the sensors data interpretation in the post-mission activities. It is concerned with the mosaicking of the aerial images and the cartography enrichment by human sensors—the social media users. We also describe the software architecture for the development of a mash-up (the integration of information and functionalities coming from the Web) and the possibility of using human sensors in the monitoring of the territory, a field in which, traditionally, the involved sensors were only the hardware ones.JRC.H.6-Digital Earth and Reference Dat

Enforcement Guide: Near Shore Artisanal Fisheries

We need healthy oceans to support our way of life. Unfortunately, fish stocks are under growing pressure and the need to find innovative and pragmatic resource management strategies is more important than ever. Disregard for fisheries and environmental laws is common and if we are to succeed in reversing the declining trend, we must draft relevant regulations, design and fund comprehensive enforcement programs and cultivate a culture of compliance. Historically, marine law enforcement has been the competency of Naval and Coast Guard authorities; however, many fishery and park agencies, who lack training, equipment, and at times controlling legal authority, are tasked with fisheries management and enforcement. Complicating matters, most agencies are understaffed; lack budgetary resources, and possess limited authority (i.e. power of arrest and the ability to use force). WildAid in cooperation with The Nature Conservancy developed this guide to assist managers in designing a cost effective enforcement strategy for near shore artisanal fisheries. This document is not a recompilation of literature, but a practical guide based on our experience in the Eastern and Western Pacific. Generally, an enforcement system is designed to monitor all activities within a given area ranging from tourism, investigation, and transportation to fisheries; however, this guide will focus primarily on near shore artisanal fisheries. The objectives of this guide are three-fold:1. Examine all factors considered for the design and operation of a marine law enforcement system; 2. Illustrate key components of an enforcement system and evaluate surveillance technology and patrol equipment options; 3. Guide managers in the design and implementation of an enforcement system.In summary, it aims to equip managers with the tools needed to strengthen fisheries management and design enforcement systems that are practical, affordable and feasible to implement in a timely manner. Fisheries enforcement requires a holistic approach that accounts for surveillance, interdiction, systematic training, education and outreach and lastly, meaningful sanctions. Although it explores many surveillance technologies and management tools, this guide more importantly provides a blueprint for the capacity building and professionalization of enforcement officers, who truly are the core component of any fisheries enforcement program

To Develop a Database Management Tool for Multi-Agent Simulation Platform

Depuis peu, la Modélisation et Simulation par Agents (ABMs) est passée d'une approche dirigée par les modèles à une approche dirigée par les données (Data Driven Approach, DDA). Cette tendance vers l’utilisation des données dans la simulation vise à appliquer les données collectées par les systèmes d’observation à la simulation (Edmonds and Moss, 2005; Hassan, 2009). Dans la DDA, les données empiriques collectées sur les systèmes cibles sont utilisées non seulement pour la simulation des modèles mais aussi pour l’initialisation, la calibration et l’évaluation des résultats issus des modèles de simulation, par exemple, le système d’estimation et de gestion des ressources hydrauliques du bassin Adour-Garonne Français (Gaudou et al., 2013) et l’invasion des rizières du delta du Mékong au Vietnam par les cicadelles brunes (Nguyen et al., 2012d). Cette évolution pose la question du « comment gérer les données empiriques et celles simulées dans de tels systèmes ». Le constat que l’on peut faire est que, si la conception et la simulation actuelles des modèles ont bénéficié des avancées informatiques à travers l’utilisation des plateformes populaires telles que Netlogo (Wilensky, 1999) ou GAMA (Taillandier et al., 2012), ce n'est pas encore le cas de la gestion des données, qui sont encore très souvent gérées de manière ad-hoc. Cette gestion des données dans des Modèles Basés Agents (ABM) est une des limitations actuelles des plateformes de simulation multiagents (SMA). Autrement dit, un tel outil de gestion des données est actuellement requis dans la construction des systèmes de simulation par agents et la gestion des bases de données correspondantes est aussi un problème important de ces systèmes. Dans cette thèse, je propose tout d’abord une structure logique pour la gestion des données dans des plateformes de SMA. La structure proposée qui intègre des solutions de l’Informatique Décisionnelle et des plateformes multi-agents s’appelle CFBM (Combination Framework of Business intelligence and Multi-agent based platform), elle a plusieurs objectifs : (1) modéliser et exécuter des SMAs, (2) gérer les données en entrée et en sortie des simulations, (3) intégrer les données de différentes sources, et (4) analyser les données à grande échelle. Ensuite, le besoin de la gestion des données dans les simulations agents est satisfait par une implémentation de CFBM dans la plateforme GAMA. Cette implémentation présente aussi une architecture logicielle pour combiner entrepôts deIv données et technologies du traitement analytique en ligne (OLAP) dans les systèmes SMAs. Enfin, CFBM est évaluée pour la gestion de données dans la plateforme GAMA à travers le développement de modèles de surveillance des cicadelles brunes (BSMs), où CFBM est utilisé non seulement pour gérer et intégrer les données empiriques collectées depuis le système cible et les résultats de simulation du modèle simulé, mais aussi calibrer et valider ce modèle. L'intérêt de CFBM réside non seulement dans l'amélioration des faiblesses des plateformes de simulation et de modélisation par agents concernant la gestion des données mais permet également de développer des systèmes de simulation complexes portant sur de nombreuses données en entrée et en sortie en utilisant l’approche dirigée par les données.Recently, there has been a shift from modeling driven approach to data driven approach inAgent Based Modeling and Simulation (ABMS). This trend towards the use of data-driven approaches in simulation aims at using more and more data available from the observation systems into simulation models (Edmonds and Moss, 2005; Hassan, 2009). In a data driven approach, the empirical data collected from the target system are used not only for the design of the simulation models but also in initialization, calibration and evaluation of the output of the simulation platform such as e.g., the water resource management and assessment system of the French Adour-Garonne Basin (Gaudou et al., 2013) and the invasion of Brown Plant Hopper on the rice fields of Mekong River Delta region in Vietnam (Nguyen et al., 2012d). That raises the question how to manage empirical data and simulation data in such agentbased simulation platform. The basic observation we can make is that currently, if the design and simulation of models have benefited from advances in computer science through the popularized use of simulation platforms like Netlogo (Wilensky, 1999) or GAMA (Taillandier et al., 2012), this is not yet the case for the management of data, which are still often managed in an ad hoc manner. Data management in ABM is one of limitations of agent-based simulation platforms. Put it other words, such a database management is also an important issue in agent-based simulation systems. In this thesis, I first propose a logical framework for data management in multi-agent based simulation platforms. The proposed framework is based on the combination of Business Intelligence solution and a multi-agent based platform called CFBM (Combination Framework of Business intelligence and Multi-agent based platform), and it serves several purposes: (1) model and execute multi-agent simulations, (2) manage input and output data of simulations, (3) integrate data from different sources; and (4) analyze high volume of data. Secondly, I fulfill the need for data management in ABM by the implementation of CFBM in the GAMA platform. This implementation of CFBM in GAMA also demonstrates a software architecture to combine Data Warehouse (DWH) and Online Analytical Processing (OLAP) technologies into a multi-agent based simulation system. Finally, I evaluate the CFBM for data management in the GAMA platform via the development of a Brown Plant Hopper Surveillance Models (BSMs), where CFBM is used ii not only to manage and integrate the whole empirical data collected from the target system and the data produced by the simulation model, but also to calibrate and validate the models.The successful development of the CFBM consists not only in remedying the limitation of agent-based modeling and simulation with regard to data management but also in dealing with the development of complex simulation systems with large amount of input and output data supporting a data driven approach

Robust Modular Feature-Based Terrain-Aided Visual Navigation and Mapping

The visual feature-based Terrain-Aided Navigation (TAN) system presented in this thesis addresses the problem of constraining inertial drift introduced into the location estimate of Unmanned Aerial Vehicles (UAVs) in GPS-denied environment. The presented TAN system utilises salient visual features representing semantic or human-interpretable objects (roads, forest and water boundaries) from onboard aerial imagery and associates them to a database of reference features created a-priori, through application of the same feature detection algorithms to satellite imagery. Correlation of the detected features with the reference features via a series of the robust data association steps allows a localisation solution to be achieved with a finite absolute bound precision defined by the certainty of the reference dataset. The feature-based Visual Navigation System (VNS) presented in this thesis was originally developed for a navigation application using simulated multi-year satellite image datasets. The extension of the system application into the mapping domain, in turn, has been based on the real (not simulated) flight data and imagery. In the mapping study the full potential of the system, being a versatile tool for enhancing the accuracy of the information derived from the aerial imagery has been demonstrated. Not only have the visual features, such as road networks, shorelines and water bodies, been used to obtain a position ’fix’, they have also been used in reverse for accurate mapping of vehicles detected on the roads into an inertial space with improved precision. Combined correction of the geo-coding errors and improved aircraft localisation formed a robust solution to the defense mapping application. A system of the proposed design will provide a complete independent navigation solution to an autonomous UAV and additionally give it object tracking capability
