Moving Object Trajectories Meta-Model And Spatio-Temporal Queries
In this paper, a general moving object trajectories framework is put forward
to allow independent applications processing trajectories data benefit from a
high level of interoperability, information sharing as well as an efficient
answer for a wide range of complex trajectory queries. Our proposed meta-model
is based on ontology and event approach, incorporates existing presentations of
trajectory and integrates new patterns like space-time path to describe
activities in geographical space-time. We introduce recursive Region of
Interest concepts and deal mobile objects trajectories with diverse
spatio-temporal sampling protocols and different sensors available that
traditional data model alone are incapable for this purpose.Comment: International Journal of Database Management Systems (IJDMS) Vol.4,

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
Análisis urbano y comunidades inteligentes: “una aproximación al empleo de la tecnología en la movilidad cotidiana”
Concentration of population in urban centers
is a global problem for which different strategies in
order to organize different processes in cities and improve
the quality of life are required. The creation of
smart communities is shown as a sustainable solution
since they deal with various key aspects, such as traffc
management and mobility, through the use of information
technologies (ITs). This work presents a review of
recent studies using information technologies for urban
analysis and mobility in cities. A descriptive analysis
of automated methods for collecting and analyzing citizens’
mobility patterns is performed; it is centered in
smart card use, geolocation and geotagging. It is concluded
that a robust communication infrastructure, supported
by an effcient computational platform allowing
big data management and ubiquitous computing, is a
crucial aspect for urban management in a smart community.La concentración de la población en los centros
urbanos es una problemática mundial que requiere de estrategias
que permitan organizar sus procesos y mejorar
la calidad de vida. La creación de comunidades inteligentes
se muestra como una solución sostenible, debido a que
éstas trabajan aspectos claves para el desarrollo urbano,
como la gestión de tráfco y la movilidad, apoyada en las
tecnologías de la información (TICs). Este trabajo presenta
una revisión del estado del arte en cuanto a la aplicación
de las TICs al análisis urbano y movilidad ciudadana. Se
analizan descriptivamente diversos métodos automáticos
para la recolección y el análisis del patrón de movilidad de
los ciudadanos, enfocándose en el uso de tarjetas inteligentes,
geolocalización y geoetiquetado. Se encuentra que una
infraestructura de comunicaciones robusta, apoyada en
una plataforma computacional ágil con manejo de grandes
datos y computación ubicua, es primordial para la gestión
