ABSTRACT In this study, previously the geographic information retrieval concept and its principles with geographic information retrieval systems were examined, which used for retrieve geographic/geospatial information and knowledge sources. Accordingly, open geographic data concept analyzed with the components of open data, government data and open government data. Open geographic data retrieval constitutes the core of the study. Also, Spatial Data Infrastructures (SDI) that enables retriving and sharing data and perception manners of open geographic data concept at world integrated the study. With the evaluated results, open data and open geographic/geospatial data exercises of Turkey in the past few years investigated for open government consciousness. Thus, reasons of the not establishing a national geographic information retrieval system evaluated and some recommendations provided on national geographic information retrieval.

Today, Spatial Data Infrastructures (SDIs) play a key role in spatial information sharing. Since their beginning, SDIs undertook tremendous changes. Product-based (first-generation)models evolved to process-based (second-generation) SDI models. Now we face shift to user-centric, third-generation SDI. Compared to former SDI concepts, the development of third-generation SDI is increasingly driven by users. Within the framework of the EU project Nature-SDIplus, we proposed the application of the interdisciplinary and wide-ranging concept of usability relating to commonly known software development processes as solution to design a user-centric SDI. Based on the results of a Europe-wide user survey, the status quo on nature conservation’s spatial data use was described, user requirements were specified,target user groups of a domain specific SDI were identified, and recommendations made to contribute to user-centric Nature-SDI.

O Centro de Informação Geoespacial do Exército (CIGeoE) tem como missão prover informação geográfica ao Exército e a outras entidades, sendo indissociável, também, a forma do seu provimento. Acompanhando a evolução tecnológica mundial, o CIGeoE fez chegar a cartografia que produz, a quem dela necessita, através de aplicações para desktop, dispositivos móveis e serviços e aplicações web. No momento presente, o foco de desenvolvimento foi para um novo geoportal, designado por Sistema de Informação Geográfica para Apoio às Operações (SIGOp), que disponibiliza, aos seus utilizadores, uma série de facilidades e ferramentas que, acredita-se, se tornarão indispensáveis para o apoio geoespacial ao nível do planeamento, condução e execução de operações, exercícios e quotidiano das Unidades, Estabelecimentos e Órgãos.
O SIGOp assenta em tecnologia open-source, respeitando os atuais standards no que se relaciona com a informação geoespacial, possuindo, também por estes motivos, uma elevada margem de progressão e longevidade. Este, não contempla, ainda, todas as especificações definidas para a primeira versão. No entanto, ultrapassa já as funcionalidades do geoportal que substitui, podendo-se constituir como ferramenta de apoio à geodecisão de comandantes.

L’ampia quantità e qualità delle idee innovative, creative, astratte o pratiche, delle conoscenze e degli strumenti, non rappresentano un vero e proprio valore fin quando non trovano un punto d’incontro, uno spazio dove interagire e confrontarsi, entrare dunque in connessione. Pertanto, il gruppo, composto da competenze interdisciplinari (geografia, architettura, ingegneria, relazioni internazionali) che ha dato vita al progetto, trova la sua convergenza sulla rigenerazione delle risorse abbandonate mediante la connessione, condivisione e partecipazione. Infatti, tali risorse sono elementi fortemente trasversali e ricchi di significato che facilmente trovano spazio tra le varie discipline; inoltre, nella maggior parte dei casi sono strutture consunte e scheletriche, anche imponenti, inglobate dal nuovo tessuto continuando a rimanere sotto gli occhi di tutti e costituendo quello che viene definito il terzo paesaggio (2), angoli del diverso che suscitano curiosità e nuove at- trazioni artistiche, del degrado, dell’abbandono, di riappropriazione della natura, raccontando sto- rie passate sugli interventi antropici.
Inoltre, ci sarà un’importante differenziazione sulle tipologie di risorse abbandonate e del loro potenziale valore di recupero: beni culturali e resti archeologici in attesa di un’adeguata tutela e valorizzazione, strutture incompiute, sentieri ed antiche tratte viarie, strutture agricole con annessi terreni ed il loro sistema di conoscenze e tradizioni, aree forestali non correttamente gestite, impianti di archeo- logia industriale.
Preso atto dell’insostenibilità del progressivo consumo di suolo, l’attenzione torna ai luoghi in crisi precedentemente elencati, non considerando solamente il principio del singolo recupero, bensì della rigenerazione, far rinascere a nuova vita, ricostituire o creare nuove relazioni sociali poiché impoverite o interrotte (Haddock, Moulaert, 2009, p. 7); non serve solo una nuova forza economica ma anche relazionale, territoriale e sociale. Passare ad una prospettiva di rigenerazione significa mettere in gioco molte più componenti della città e del territorio e non i soli ambiti circoscritti, tra le quali le potenzialità endogene dello stesso (Sbetti, Rossi, Talia, Trillo, 2013, p. 17), approcciandosi all’evoluzione del tessuto edificato e non, ma anche alle relazioni sociali inclusive.
L’eterogeneità della rigenerazione presuppone nuovi modelli di sviluppo, volti appunto all’inclusione sociale e alla partecipazione, progetti socialmente innovativi, in grado di offrire nuove risposte a continui problemi sociali.

Geo-Information (GI) professionals, researchers and users have constantly
proclaimed the potential of GI in facilitating more skillful and effective solutions to a wide
variety of problems across today’s modern society. However, the successful application of
GI to a wider cross-section of today’s society requires that GI is made available for sharing
and using. For GI to be shared and used on a large scale it must be easily accessable in an
efficient and user-friendly format. To facilitate the sharing and using of GI many countries
are implementing Spatial Data Infrastructures (SDIs). A key component of an SDI that
facilitates accessibility and access to GI datasets is a Geoportal. In general, a Geoportal
acts as a gateway to digital GI content and services made available within the concept of an
SDI. The Geoportal achieves this goal through the linking of GI oriented websites and
databases. These websites may be local, regional, national, public or privately owned.
Within the context of an SDI it is propagated that there should be a single entry point (a
National Geoportal) to GI content and services for a nation. In this paper we will try to
describe how we would create Geoportal as a functional, capable service for collecting,
analyzing and publishing GI for specified areas.

Este trabajo pretende analizar la interaccion del usuario final con un geoportal. Para este proposito, se evalua la medida en que se cumplen las expectativas y necesidades del usuario, el grado probable de dificultad que enfrenta, asi como el nivel de satisfaccion que alcanza en un sitio web. Se analiza especialmente el caso en que el geoportal ha sido creado en base a objetivos y necesidades del promotor, pero sin tener en cuenta las expectativas, necesidades y limitaciones del usuario. Para este fin, se realizo el analisis del portal del Sistema de Informacion del Atlas Nacional de Espana en la web (SIANEweb) mediante tecnicas inherentes al Diseno Centrado en el Usuario (DCU). Este enfoque es particularmente util al evaluar la capacidad de un geoportal para resolver necesidades reales del usuario. El DCU es iterativo, por lo que se puede aplicar a cada una de las etapas en el desarrollo de un prototipo, asi como a un sitio ya operativo como el caso del SIANEweb, con el fin de alca...

This study focuses on the development of a web national atlas as an alternative means to geoportals, when accessing a Geospatial Data Infrastructure (GDI). The development of the atlas metaphor was undertaken throughout the problem space, design space, and evaluation space by combining techniques in Human-Computer Interaction and Geovisualization. During the development of the atlas metaphor, in the problem space, design space, and evaluation space, potential users were involved and scenarios were employed in order to guide and validate the design decisions. The problem space: Activities of geoportals' reviews and contextual inquiries into the use of the current Dutch clearinghouse were undertaken in order to develop an understanding of the usability issues in geoportals. From these activities, it was apparent that interaction methods and information presented in many geoportals (to help user review and make sense of the search results) are far from optimal. The virtue of maps and graphics in order to stimulate visual thinking and to provide effective communication before and after "a search" in current geoportals have not yet been considered essential. When thinking of a solution to the usability issues associated with the use of national geoportals or clearinghouses, the recognizable concept of a national atlas is recalled. The decision to select the national atlas as the source of metaphor is based on the similarity of the functional definition of geoportals or clearinghouses and national atlases as search and access tools. Thus, in order to generate design ideas on how the national atlas should be developed to overcome the current usability issues of geoportals, this study adapted the prospective use of the atlas schemata. The prospective use of the atlas schemata includes the prominent role of maps in the atlas and the organizational approach of the atlas. Therefore, as a result of the adaptation of the national atlas schemata, operational functionalities related to searching and browsing information seeking behaviour to help users locating information using the national atlas were envisioned and framed into a rapid prototype. The design space: The specifications of functions generated from the problem space were transformed into a working prototype of the atlas interface metaphor for improved use and accessibility of the GDI, called Aim4GDI. The Aim4GDI applied the atlas information structure. This structure was built as the basis for implementing the realization of an adaptation of the atlas schemata and designed to organize thematic maps, images, graphics and information resources related to the GDI including metadata summaries. Metadata summaries are aggregated metadata of geospatial resources in the GDI like offline data, Web Map Services (WMS), Web Feature Services (WFS), and other online information resources such as geocoded news. The application framework of the prototype combines the metadata and query language for the Semantic Web with cartographic design templates in aggregating, managing, and visualizing metadata summaries. The Aim4GDI enables users to search and browse geospatial resources through developed visual methods. The table view, thumbnail view, bull's-eye view, and Parallel Coordinate Plots (PCP) view) are as the name suggests, visual methods that can help users indicate, compare, and associate the search results. Meanwhile, in order to help users browse and xi Ringkasan Penelitian ini mengkaji pembangunan atlas nasional berbasis internet sebagai alternatif dari geoportal dalam mengakses Infrastruktur Data Geospasial (IDG). Pembangunan atlas sebagai sebuah metafora dilakukan dalam ruang lingkup masalah, ruang lingkup desain, dan ruang lingkup evaluasi, melalui penggabungan teknik-teknik dalam bidang Interaksi Manusia-Komputer (IMK) dan Geovisualisasi dengan melibatkan pengguna potensial dan skenario penggunaan untuk mendapatkan hasil desain yang tepat dan terarah. Ruang lingkup masalah: Kajian terhadap beberapa geoportal dan penyelidikan kontekstual pada penggunaan antarmuka 'clearinghouse' negeri Belanda dilakukan untuk memahami aspek-aspek efektivitas, efisiensi, dan kepuasan dalam menggunakan geoportal-geoportal yang ada. Dari kedua aktivitas tersebut, dapat disimpulkan bahwa metode-metode interaksi berikut informasi yang tersaji di banyak geoportal masih jauh dari optimal. Manfaat peta dan grafik dalam merangsang cara berpikir visual dan dalam mengkomunikasikan informasi secara efektif untuk menunjang aktivitas interaksi sebelum dan sesudah 'sebuah pencarian' pada semua geoportal yang telah ada, masih sangat terbatas. Dalam mencari solusi guna memperbaiki aspek kegunaan geoportal nasional, konsep atlas nasional didayagunakan dalam penelitian ini. Atlas nasional dipilih, karena konsep ini memiliki kemiripan fungsi dengan geoportal atau 'clearinghouse' sebagai alat pencari dan penyedia akses informasi dan data geospasial. Untuk menggali ide desain bagaimana atlas nasional harus dibangun, dilakukan adaptasi terhadap skemaskema atlas yang dianggap menguntungkan dalam membantu memecahkan masalah kegunaan dari geoportal-geoportal yang ada. Skema-skema atlas yang diadaptasi meliputi peran peta dan aspek organisasi data di dalam atlas. Hasil dari proses adaptasi skema-skema atlas nasional adalah fungsi-fungsi operasional untuk mendukung aktivitas penelusuran ("searching") dan penjelajahan ("browsing") yang diperlukan para pengguna untuk menemukan informasi melalui atlas nasional. Fungsi-fungsi tersebut selanjutnya diperinci dan diujicobakan pada sebuah prototipe cepat. xiii Contents Summary vii Samenvatting ix Ringkasan xi Contents xiii List of Figures xvii List of Tables xxi List of Acronyms xxiii 1.2.

Demands for geospatial information and geodata accessibility to support vineyard management using new technology for precision farming are increasing worldwide. In this paper a WebGIS application is presented, it has been developed to support the on-going researches of Consorzio Tuscania Project on precision viticulture in Tuscany, aiming at the assessment of the impact of different vineyard canopy management techniques on grape quality. Within this framework, a parallel goal was also to build a Web service to support operational applications for agronomic treatments and grape harvest and to provide digital images for mobile devices that can be also integrated on agricultural machineries. A geoportal has been developed to organize geospatial data and services through (i) a viewer, (ii) a catalogue containing metadata records and (iii) a geodatabase where all data and results of Research Project are stored. Thanks to web services, users can view, analyse and download vegetation indic...

OGC Web Services (OWS) are essential building blocks for the national and global spatial data infrastructure (NSDI and GSDI) and the geospatial cyberinfrastructure (GCI). Web Map Service (WMS), Web Feature Service (WFS), Web Coverage Service (WCS), and Catalogue Service for Web (CSW) have been increasingly adopted to serve scientific data. Interoperable services can facilitate the integration of different scientific applications by searching, finding, and utilizing the large number of scientific data and Web services. However, these services are widely dispersed and hard to be found and utilized with acceptable performance. This is especially true when developing a science application to seamlessly integrate multiple geographically dispersed services. Focusing on the integration of distributed OWS resources, we propose a layer-based service-oriented integration framework and relevant optimization technologies to search and utilize relevant resources. Specifically, (1) an AJAX (Asynchronous JAvaScript and eXtensible Markup Language)-based synchronous multi-catalogue search is proposed and utilized to enhance the multi-catalogue searching performance; (2) a layer-based search engine with spatial, temporal, and performance criteria is proposed and used for identifying better services; (3) a service capabilities clearinghouse (SCCH) is proposed and developed to address the service issues identified by a statistical experiment. A science application of data correlation analysis is used as an example to demonstrate the performance enhancement of the proposed framework.

Plan4All project contributes on the harmonization of spatial data and related metadata in order to make them available through Web across a linked data platform. A prototype of a Web search European spatial data portal is already available at http://www.plan4all.eu. The key aim is to provide a methodology and present best practices towards the standardization of spatial data according to the INSPIRE principles and provide results that would be a reference material for linking data and data specification from the spatial planning point of view. The results include methodology and implementation of multilingual search for data and common portrayal rules for content providers. These are critical services for sharing and understanding spatial data across Europe. Plan4All paradigm shows that a clear applicable methodology for harmonization of spatial data on all different topics of interest can be achieve efficiently. Plan4All shows that it is possible to build Pan European Web access, to link spatial data and to utilize multilingual metadata providing a roadmap for linked spatial data across and hopefully beyond Europe. The proposed demonstration based on Plan4All experience aims to show experience, best practices and methods to achieve data harmonization and provision of linked spatial data on the Web.

Flood protection is one of several disciplines where geospatial data is very important and is a crucial component. Its management, processing and sharing form the foundation for their efficient use; therefore, special attention is required in the development of effective, precise, standardized, and interoperable models for the discovery and publishing of data on the Web. This paper describes the design of a methodology to discover Open Geospatial Consortium (OGC) services on the Web and collect descriptive information, i.e., metadata in a geocatalogue. A pilot implementation of the proposed methodology - Geocatalogue of geospatial information provided by OGC services discovered on Google (hereinafter “Geocatalogue”) - was used to search for available resources relevant to the area of flood protection. The result is an analysis of the availability of resources discovered through their metadata collected from the OGC services (WMS, WFS, etc.) and the resources they provide (WMS layers...

This article presents research and development of an interoperable platform to facilitate, monitor and coordinate groundwater data sharing. This system was orchestrated by a number of services described by Open Geospatial Consortium (OGC) such as Sensor Observation Service (SOS) and other services for the use of mapping data, Web Feature Services (WFS), Web Map Service (WMS), and catalogue services (CSW). An important activity for our project was the establishment of a portal for geographic data and services. Geoportal developed for this project will promote and facilitate access to groundwater data and share theme more openly. Otherwise our system has been designed to provide a powerful tool that enhances the ability of regional staff to monitor near real-time groundwater data (i.e. piezometric level) and as a result will help provide a more effective response to environmental upsets.
