Abstract. Sharing and management of geospatial data among different communities and users is a challenge which is suitably addressed by Spatial Data Infrastructure (SDI). SDI helps people in the discovery, editing, processing and visualization of spatial data. The user can download the data from SDI and process it using the local resources. However, large volume and heterogeneity of data make this processing difficult at the client end. This problem can be resolved by orchestrating the Web Processing Service (WPS) with SDI. WPS is a service interface through which geoprocessing can be done over the internet. In this paper, a WPS enabled SDI framework with OGC compliant services is conceptualized and developed. It is based on the three tier client server architecture. OGC services are provided through GeoServer. WPS extension of GeoServer is used to perform geospatial data processing and analysis. The developed framework is utilized to create a public health SDI prototype using Open Source Software (OSS). The integration of WPS with SDI demonstrates how the various data analysis operations of WPS can be performed over the web on distributed data sources provided by SDI.

The chapter presents examples of applications and study cases of platforms of geospatial decision support systems for national public policies and strategies. The rapid progress of internet with the combination of GIS has paved the ways for web distribution of spatial data. Users can access the spatial data through a Web-GIS website, make thematic maps, and perform all types of spatial queries and analysis. In the context of an increasing emphasis on decentralized planning, the need for collection and dissemination of data at local levels has been increased. Use of the web as a dissemination medium of geographic data in the form of interactive maps can be regarded as a major advancement in digital cartography and opens many new opportunities, such as real-time maps, cheaper dissemination, and decentralized sharing of geographic information.

The article discusses possibilities of geochronological tracking technology for studying the spatial mobility of social groups in Russia in the past. The GIS proposed is necessary to visualize and analyze spatial data in a prosopographic research of about 400 szlachta representatives in Peter’s Epoch. Spatial mobility is understood as the intensity of person's translocation through settlements and his ability to respond to external challenges by moving. The archival materials of the Senate inspection of the szlachta (1721-1723) served the basis for the study and the resource formation. Particular attention is paid to the design of software research tools – the PostgreSQL database and the web GIS based on the latter. It is the first time when geochronological tracking as a geoinformatics method was used to prosopographically study the Russian nobility. The methods of historical source spatial data representation and visualization are implemented in the form of a geodatabase that is publicly available. Two program modules (the GIS among them) grant a wide range of Internet users an access to historical sources text data as well as synchronically visualized data on the szlachta service under Peter the first.  The authors conclude that it is promising to create a special web interface which provides users with flexible text and geodata filtering and analysis. The web project created can be used both for research in the field of social history, historical geography, genealogy and for educational purposes in such courses as “historical computer science” and “digital humanities”.

The effective access and use of geospatial information (GI) resources acquires a critical value of importance in modern knowledge based society. Standard web services defined by Open Geospatial Consortium (OGC) are frequently used within the implementations of spatial data infrastructures (SDIs) to facilitate discovery and use of geospatial data. This data is stored in databases located in a layer, called the invisible web, thus are ignored by search engines. SDI uses a catalogue (discovery) service for the web as a gateway to the GI world through the metadata defined by ISO standards, which are structurally diverse to OGC metadata. Therefore, a crosswalk needs to be implemented to bridge the OGC resources discovered on mainstream web with those documented by metadata in an SDI to enrich its information extent. A public global wide and user friendly portal of OGC resources available on the web ensures and enhances the use of GI within a multidisciplinary context and bridges the geospatial web from the end-user perspective, thus opens its borders to everybody. <br><br> Project “Crosswalking the layers of geospatial information resources to enable a borderless geospatial web” with the acronym BOLEGWEB is ongoing as a postdoctoral research project at the Faculty of Geodesy, University of Zagreb in Croatia (http://bolegweb.geof.unizg.hr/). The research leading to the results of the project has received funding from the European Union Seventh Framework Programme (FP7 2007-2013) under Marie Curie FP7-PEOPLE-2011-COFUND. The project started in the November 2014 and is planned to be finished by the end of 2016. This paper provides an overview of the project, research questions and methodology, so far achieved results and future steps.

Spatial Data Infrastructures (SDIs) are a key asset for Europe. This paper concentrates on unsolved issues in SDIs in Europe related to the management of semantic heterogeneities. It studies contributions and competences from two communities in this field: cartographers, authoritative data providers, and geographic information scientists on the one hand, and computer scientists working on the Web of Data on the other. During several workshops organized by the EuroSDR and Eurogeographics organizations, the authors analyzed their complementarity and discovered reasons for the difficult collaboration between these communities. They have different and sometimes conflicting perspectives on what successful SDIs should look like, as well as on priorities. We developed a proposal to integrate both perspectives, which is centered on the elaboration of an open European Geographical Knowledge Graph. Its structure reuses results from the literature on geographical information ontologies. It is associated with a multifaceted roadmap addressing interrelated aspects of SDIs.

The best tools to manage the exchange of information and services between heterogeneous subjects through new technological tools with particular reference to information systems are certainly the Web-based information systems. Leveraging the infrastructure of the Web, these systems may be able to handle multimedia data, to perform distributed and cooperative applications based on service, in addition to customizing applications and related data. This paper provides an overview on Web Information Systems with particular reference to GIS, presenting a description of the usage scenarios and a comparison between two significant platform for publishing spatial data.
