Geospatial extensions of SPARQL like GeoSPARQL and stSPARQL have recently been defined and corresponding geospatial RDF stores have been implemented. However, there is no widely used benchmark for evaluating geospatial RDF stores which takes into account recent advances to the state of the art in this area. In this paper, we develop a benchmark, called Geographica, which uses both real-world an...

Most civil engineering tasks require accessing, surveying and modifying geospatial data in the field and referencing this virtual, geospatial information to the real world situation. Augmented Reality (AR) can be a useful tool to create, edit and update geospatial data representing real world artifacts by interacting with the 3D graphical representation of the geospatial data augmented in the u...

Geospatial databases include any data with reference to geocoordinate information. The geospatial data can either be digital raster images that represent the data on the earth in the form of pixels or digital vector data that is primarily from satellites. Due to the fact that many of the high-resolution satellites are commercial in nature, uncontrolled dissemination of the high resolution image...

Water resources management is critical due to its importance for human lives. In this context, we have developed a web-based system for hydrological applications that integrates geospatial processing services and mapping mashups to provide an interactive and user-friendly geoportal interface to the configuration and execution of scientific models. The server side provides hydrological model log...

Recent advances in Service-Oriented Architecture (SOA) and in geospatial Web services and interoperability technologies are shifting geospatial data and analysis from the everything-locally-owned-and-operated paradigm to the everything-shared-over-the-Web paradigm (Web-and-ServiceCentric paradigm). By embracing geospatial content and capabilities within the context of SOA, we have developed a W...

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...

To help users discover the most relevant spatial datasets in the ever-growing global spatial data infrastructures (SDIs), a number of similarity measures of geospatial data based on metadata have been proposed. Researchers have assessed the similarity of geospatial data according to one or more characteristics of the geospatial data. They created different similarity algorithms for each of the ...

Geospatial reasoning has grown larger scope in the semantic web. Increasinglymore information is geolocated,moremobile devices produce geocoded records, and more web mashups are created to convey geospatial information. Semantics can support the integration of geospatial information, track the provenance and quality of the data shown to an end user, and improve visualizations and querying of ge...
