Bolegweb project - contributions to a global SDI and Geospatial Web

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 a spatial data infrastructure (SDI) to facilitate discovery and use of geospatial resources as data and services. This data is stored in databases located in a layer, identified in previous research works as invisible web, and 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 often 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. 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) and Croatian Ministry of Science 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 contribution provides an overview of the project, research questions and methodology aiming to contribute to the activities under global SDI initiatives as well as support other communities on the web interested in using geospatial resources shared via OGC services.
