La EIEL y los Geoportales: cómo poner la información a disposición de la ciudadanía

El empleo de las Sistemas de Información Geográfica (SIG) ha ido ganando terreno poco a poco, durante los últimos años, en la realización de la Encuesta de Infraestructura y Equipamientos Locales (EIEL). La transposición de la directiva europea 2007/02/EC para establecer una Infraestructura de Información Espacial en la Comunidad Europea (INSPIRE) ha hecho que las administraciones, tanto locales como estatales, busquen mecanismos para la publicación de los datos geográficos y en el caso de la EIEL no es una excepción. El auge de las nuevas tecnologías han hecho que poco a poco Internet esté presente cada vez más en nuestras vidas, convirtiéndose probablemente en el medio más utilizado y más ágil para la comunicación. Los Sistemas de Información Geográfica, consolidados ya en el escritorio, han ido también, de forma paulatina incorporándose a la nube, ofreciendo casi las mismas ventajas al almacenar, editar y compartir información. Las tecnología actuales más potentes están además, muchas de ellas, basadas en el Software Libre y evolucionan de forma extremadamente rápida. Pero, ¿es realmente necesaria siempre toda esta tecnología? ¿es necesario que los Sistemas de Información Geográfica abandonen por completo el escritorio para mudarse a la web? A través del análisis de los Geoportales que varias administraciones han creado para divulgar y compartir los datos obtenidos en la EIEL, en este documento se intentará dar respuesta a estas preguntas basándose en indicadores objetivos sobre la aplicación actual que se está haciendo de estas tecnologías

LEGENDiary: web 2.0 y app móvil

LEGENDiary es un geoportal 2.0 que permite compartir y explorar las leyendas y cuentos característicos de las ciudades de una manera dinámica y colaborativa. Muchas veces las leyendas forman parte de la historia y cultura de nuestros pueblos o ciudades, LEGENDiary nos permite conocerlas según el territorio donde se ubican. La iniciativa promueve nuevas formas de conocer y explorar el territorio, en general, y las leyendas y cuentos de nuestros pueblos y ciudades, en particular. Un proyecto que permite a los usuarios interactuar y ser protagonistas de esta experiencia. El proyecto parte inicialmente de un contexto español, y se trata de un proyecto hecho a medida de todas aquellas personas interesadas y con curiosidad en compartir, conocer y explorar las leyendas en el territorio. La combinación de las Tecnologías de la Información Geográfica y las Tecnologías 2.0 es el escenario donde surge LEGENDiary, aportando la componente geográfica a las leyendas y cuentos de los pueblos y ciudades en un contexto colaborativo. La iniciativa se lanza el día 16 de noviembre de 2011 en formato concurso con motivo del Día Internacional de los Sistemas de Información Geográfica (GISDay). Para llevar a cabo la aplicación se han utilizado dos librerías Javascript (Leaflet y jQuery) de código abierto y gratuito que permiten crear de forma rápida y ligera aplicaciones de mapas interactivos a través de navegadores web (de escritorio y móvil). Como mapa base se ha utilizado Open Street Map.LEGENDiary es una iniciativa del Servicio de SIG y Teledetección (SIGTE) de la Universidad de Girona en colaboración con el Departamento de Geografía y la Facultad de Turismo de la misma universidad, y con elapoyo del Hotel Llegendes de Girona

Solución de alto rendimiento para el Geoportal de Turismo de la Comunidad Valenciana

La Agència Valenciana de Turisme ha emprendido el proyecto de actualización de la web de promoción de la Comunidad Valenciana, el portal http://www.comunitatvalenciana.com. Este portal es una referencia internacional para todos los visitantes de la Comunidad Valenciana y por tanto un proyecto clave en su promoción turística. En esta ponencia se presentará la elaboración de un geoportal turístico atractivo y preparado para soportar un número elevado de visitas. En el contexto del proyecto se han abordado problemas como la visualización de información vectorial (puntos de interés) en un elevado número mediante la técnica de agregación o clustering. Por otro lado dicha información vectorial se procesa de tal forma que el visitante de la web obtiene un rendimiento en los tiempos de respuesta bastante elevado gracias al uso de técnicas de multirresolución en el visor web. La información de partida se migra a una base de datos espacial libre y se procesa para generar archivos en formato JSON. Por otro lado, el geoportal ofrece un flexible motor de búsquedas, preparado igualmente para soportar una carga elevada de peticiones mediante el uso de la indexación con el soporte para consultas espaciales. Este motor de búsquedas igualmente se ha preparado para utilizarse como servidor para ofrecer toda la información del portal a través de Layar, un servicio de realidad aumentada para móviles. Este servicio está completamente basado en componentes libres como el framework Spring o el soporte de búsquedas Lucene. Se presentará por tanto cómo se ha abordado la realización de una solución completa de presentación de información de un portal turístico de exigencias de rendimiento elevadas, centrando la atención en los componentes del servidor, todos ellos basados en software libre

Disseny i construcció d'un motor 3D en temps real per la Gameboy Advance

El projecte desenvolupat ha tractat l’estudi i disseny d’un motor 3D interactiu a la consola Game Boy Advance (GBA). La GBA disposa d’un processador ARM7TDMI a 16’78 Mhz i no disposa de operacions 3D per-hardware, és una consola lenta en comparació les que podem trobar al mercat d’avui en dia. Aquest treball, va partir de la construcció d’un prototipus ray-casting per-columna. Després, vàrem adaptar-lo a una estructura de portals i sectors. Més tard, es va introduir el mapeig de sostre/terra i de paisatges. Per últim, vàrem introduir efectes a la renderització per donar més realisme al recorregut del món, com il·luminació, objectes, etc. Tot i que es va estudiar l’arquitectura d’un motor eficient, no es tenia prou per arribar a tenir un motor interactiu. Una de les tasques més difícils va ser la part de optimització. Per aconseguir-ho s’ha hagut de substituir operacions a temps real costoses a temps de execució, replantejar parts de l’algorisme per fer-lo més eficient, entre altres

The VERA information environment

We present three components of a virtual research environment developed for the ongoing Roman excavation at Silchester. These components — Recycle Bridge, XDB cross-database search, and Arch3D — provide additional services around the existing core of the system, run on the Integrated Archaeological Database (IADB). They provide, respectively, embedding of legacy applications into portals, cross-database searching, and 3D visualisation of stratigraphic information.

The collaborative P-GRADE grid portal

Grid portals are increasingly used to provide uniform access to the grid infrastructure. This paper describes how the P-GRADE Grid Portal could be used in a collaborative manner to facilitate group work and support the notion of Virtual Organisations. We describe the development issues involved in the construction of a collaborative portal, including ensuring a consistent view between participants of a collaborative workflow and management of proxy credentials to allow separate nodes of the workflow to be submitted to different grids.

A conceptual life event framework for government-to-citizen electronic service provision

In recent years, life event approach has been widely used by governments all over the world for designing and providing web services to citizens through their e-government portals. Despite the wide usage of this approach, there is still a challenge of how to use this approach to design e-government portals in order to automatically provide personalised services to citizens. We propose a conceptual framework for e-government service provision based on life event approach and the use of citizen profile to capture the citizen needs, since the process of finding Web services from a government-to-citizen (G2C) system involves understanding the citizens’ needs and demands, selecting the relevant services, and delivering services that matches the requirements. The proposed framework that incorporates the citizen profile is based on three components that complement each other, namely, anticipatory life events, non-anticipatory life events and recurring services.

Towards a life-event oriented G2C e-service provision: the NoBLE Framework

One of the primary features of modern government-to-citizen (G2C) service provision is the ability to offer a citizen-centric view of the e-government portal. Life-event approach is one of the most widely adopted paradigms supporting the idea of solving a complex event in a citizen’s life through a single service provision. Several studies have used this approach to design e-government portals. However, they were limited in terms of use and scalability. There were no mechanisms that show how to specify a life-event for structuring public e-services, or how to systematically match life-events with these services taking into consideration the citizen needs. We introduce the NOrm-Based Life-Event (NoBLE) framework for G2C e-service provision with a set of mechanisms as a guide for designing active life-event oriented e-government portals.

A Web Map Service implementation for the visualization of multidimensional gridded environmental data

We describe ncWMS, an implementation of the Open Geospatial Consortium’s Web Map Service (WMS) specification for multidimensional gridded environmental data. ncWMS can read data in a large number of common scientific data formats – notably the NetCDF format with the Climate and Forecast conventions – then efficiently generate map imagery in thousands of different coordinate reference systems. It is designed to require minimal configuration from the system administrator and, when used in conjunction with a suitable client tool, provides end users with an interactive means for visualizing data without the need to download large files or interpret complex metadata. It is also used as a “bridging” tool providing interoperability between the environmental science community and users of geographic information systems. ncWMS implements a number of extensions to the WMS standard in order to fulfil some common scientific requirements, including the ability to generate plots representing timeseries and vertical sections. We discuss these extensions and their impact upon present and future interoperability. We discuss the conceptual mapping between the WMS data model and the data models used by gridded data formats, highlighting areas in which the mapping is incomplete or ambiguous. We discuss the architecture of the system and particular technical innovations of note, including the algorithms used for fast data reading and image generation. ncWMS has been widely adopted within the environmental data community and we discuss some of the ways in which the software is integrated within data infrastructures and portals.

Computational analysis of the LRRK2 interactome

LRRK2 was identified in 2004 as the causative protein product of the Parkinson’s disease locus designated PARK8. In the decade since then, genetic studies have revealed at least 6 dominant mutations in LRRK2 linked to Parkinson’s disease, alongside one associated with cancer. It is now well established that coding changes in LRRK2 are one of the most common causes of Parkinson’s. Genome-wide association studies (GWAs) have, more recently, reported single nucleotide polymorphisms (SNPs) around the LRRK2 locus to be associated with risk of developing sporadic Parkinson’s disease and inflammatory bowel disorder. The functional research that has followed these genetic breakthroughs has generated an extensive literature regarding LRRK2 pathophysiology; however, there is still no consensus as to the biological function of LRRK2. To provide insight into the aspects of cell biology that are consistently related to LRRK2 activity, we analysed the plethora of candidate LRRK2 interactors available through the BioGRID and IntAct data repositories. We then performed GO terms enrichment for the LRRK2 interactome. We found that, in two different enrichment portals, the LRRK2 interactome was associated with terms referring to transport, cellular organization, vesicles and the cytoskeleton. We also verified that 21 of the LRRK2 interactors are genetically linked to risk for Parkin- son’s disease or inflammatory bowel disorder. The implications of these findings are discussed, with particular regard to potential novel areas of investigation.

Gestão do Conhecimento e o uso estratégico de Tecnologias de Informação: um estudo em Redes de Franquias no Estado do Rio Grande do Norte

This study discusses the use of information technologies for knowledge management in networks of franchises in the Rio Grande do Norte/Brazil, whose management and operation are complex activities, characterized by the geographic spread of their network unities, creating barriers to communication and information sharing between franchisors, franchisees and final customers. In view of this, the following hypotheses were formulated: the knowledge management can be a positive alternative for improving communication between units; and information technology can eliminate many problems related mainly to capture and share knowledge. In general, it aims to investigate, in qualitative and quantitative aspects, how information technology can support knowledge management in networks of franchises. Specifically purposes to register the existence of managerial practices related to knowledge management in enterprises at the franchising sector; to verify whether they have the technological resources with the potential to facilitate the sharing of information; to identify what are the technologies of information and communication used in the organizational environment; and suggest measures that will facilitate the process of organizational learning, using information technology and communication as tools. It concludes that knowledge management becomes a positive alternative, especially in strengthening of bonds of communication and sharing of knowledge between the franchises. In this regard, information technology must provide all the services of the corporation to facilitate communication between franchisor and franchisee, through a single and integrated system. However, they still show unsuitable for more sophisticated technology platforms
