A catalogue service facilitates sharing, discovery, retrieval, management of, and access to large volumes of distributed geospatial resources, for example data, services, applications, and their replicas on the Internet. Grid computing provides an infrastructure for effective use of computing, storage, and other resources available online. The Open Geospatial Consortium has proposed a catalogue...

Information integration and semantic heterogeneity are not trivial tasks. An integrated view must be able to describe various heterogeneous data sources and its interrelation to obtain shared conceptualizations. In this paper, we propose an approach to make a conceptualization of the real world based on conceptual schemas, which are used to generate a semantic description of the geospatial doma...

Nowadays, globalization and rapid changes in developing countries affect the behavior and culture of people. Adapting to these changes is the vital means to remain in the competition of being a developed society. One of the most important changes is the relationship between humans and land which have evolved by way of many parameters such as globalization, urbanization, technological and econom...

In recent years, multiple geospatial ontologies have been developed for a wide range of different spatial databases. In addition, the development of volunteered geographic information both challenges and provides opportunities to the traditional authenticated geospatial information. Though volunteered geographic information is typically not as reliable and structured as the authenticated geospa...

The mobile geospatial information service involves the domain of mobile communication, mobile computing, geospatial information service and other techniques. This paper focuses on the integration of spatial information and mobile communication technologies. The author proposes the architecture of mobile geospatial information service based on the Ad Hoc network. On the basis of this architectur...

We propose an OBDA approach for accessing geospatial data stored in relational databases, using the OGC standard GeoSPARQL and R2RML or OBDA mappings. We introduce extensions to an existing SPARQL-to-SQL translation method to support GeoSPARQL features. We describe the implementation of our approach in the system ontopspatial, an extension of the OBDA system Ontop for creating virtual geospatia...

Armenia as a developing country has a very severe need to integrate and collaborate with the international Geospatial community in order to build a reliable and efficient geospatial infrastructure. Moreover, the availability of such an infrastructure could foster the availability of geospatial data, could facilitate the development of a data sharing policy at national level, and could help to e...

Semantics of geospatial information is necessary to ensure its interoperability and correct usage. Geospatial ontologies enable encoding such knowledge and enable reasoning mechanisms to estimate interoperability. The framework of interoperability for geospatial information using ontologies, presented in this paper, supports (i) building of ontologies, (ii) semi-automated, ontology-based mappin...

we designed and implemented an integration framework of enterprise business information and multi-source heterogeneous geospatial information based on composition of semantic geospatial Web service. It can integrate business information and geospatial information seamlessly and effectively in enterprise workflow. An example of tobacco planting spatial analysis this framework was described to ve...

a. an aspect of cognition (e.g., understanding the meaning and usefulness of geospatial searching, display, and evaluation); b. culture (e.g., established ways of doing things and identification of geospatial indexing solely with GIS), c. a type of technology (e.g., geospatial search functionality and representation of spatial location); or, d. funding (e.g., magnitude and availability of fundi...
