Enriching and improving the quality of linked data with GIS

Abstract

Standardization of methods for data exchange in GIS has a long history predating the creation of World Wide Web. The advent of World Wide Web brought the emergence of new solutions for data exchange and sharing including; more recently, standards proposed by the W3C for data exchange involving Semantic Web technologies and linked data. Despite the growing interest in integration, GIS and linked data are still two separate paradigms for describing and publishing spatial data on the Web. At the same time, both paradigms offer complementary ways of representing real world phenomena and means of analysis using different processing functions. The complementarity of linked data and GIS can be leveraged to synergize both paradigms resulting in richer data content and more powerful inferencing. The article presents an approach aimed at integrating linked data with GIS. The approach relies on the use of GIS tools for integration, verification and enrichment of linked data. The GIS tools are employed to enrich linked data by furnishing access to collection of data resources, defining relationship between data resources, and subsequently facilitating GIS data integration with linked data. The proposed approach is demonstrated with examples using data from DBpedia, OSM, and tools developed by the authors for standard GIS software.

Platial mobility: expanding place and mobility in GIS via platio-temporal representations and the mobilities paradigm

“…2014 ; Iwaniak et al. 2016 ; Hart and Dolbear 2016 ) and VGI (Goodchild 2007 ; Kuhn 2007 ) Meaning is the most important and distinguishing dimension of platial model and has the capability to capture cognitive sense of place at various levels of detail. Meaning then makes it possible to perform platial analysis using both geometric and semantic measurements.…”

Adapted Rules for UML Modelling of Geospatial Information for Model-Driven Implementation as OWL Ontologies

“…Spatial Data Infrastructures (SDI) provide portals and catalogue services for searching and accessing information from different service providers. However, even though WMS and WFS are based on general IT standards, they are specific standards for geospatial information, with limited possibilities for linking the information with other sources on the World Wide Web [19,20]. According to Model Driven Architecture (MDA) [14], the conceptual schemas shall be independent of any implementation technology but can be converted to implementation schemas in database and exchange formats.…”

“…Semantic Web technologies can be used to improve discovery in SDIs [24][25][26][27][28][29]. Authoritative geospatial information can be combined with less structured geospatial information from crowdsourcing, citizen science and sensors [20,30], and Semantic Web concepts for reasoning may be used to derive new knowledge [31][32][33]. Most importantly, geospatial information can be easier accessed from outside the GIS domain, linked with non-spatial information and reused between stakeholders and domains.…”

A Novel Approach for Publishing Linked Open Geodata from National Registries with the Use of Semantically Annotated Context Dependent Web Pages

“…One of the possible strategies for matching spatial objects for the purpose of publishing Linked Open Data is presented in [21]. In this approach, we selected well-known LOD hubs-DBPedia and GeoNames.…”
