Today, there is a huge amount of data gathered about the Earth, not only from new spatial information systems, but also from new and more sophisticated data collection technologies. This scenario leads to a number of interesting research challenges, such as how to integrate geographic information of different kinds. The basic motivation of this paper is to introduce a GIS architecture that can ...

Today, the discovery and sharing of geospatial information over the Web presents some difficulties which have not yet been solved. News distribution through website content was simplified by the use of Really Simple Syndication (RSS) and Atom syndication formats. This paper exposes an extension of Atom to redistribute references to geospatial information in a Spatial Data Infrastructure distrib...

3D geospatial information systems should provide efficient spatial analysis tools and able to use all capabilities of the third dimension, and a visualization. Currently, many human activities make steps toward the third dimension like land use, urban and landscape planning, cadastre, environmental monitoring, transportation monitoring, real estate market, military applications, etc. To reflect...

A growing number of studies have shown that adequate spatial access to healthy foods leads to increased fresh produce consumption and reduced risk of chronic diseases. Annual dynamics of spatial access to 1,539 vendors of fresh produce (including farmers markets and roadside farm stands) are analyzed in Massachusetts. Travel distance to the nearest fresh produce vendor was calculated for each c...

With the advent of the World Wide Web (WWW), the way people publish, retrieve and synthesise information has totally changed. The Web is a hypertext system consisting of a huge amount of information which has very different forms. The concept of geospatial Web content emphasises the geospatial context of online information. Due to the continued explosive increase in the volume and complexity of...

Spatial Data Infrastructure acts as a fundamental platform to make geospatial data exchangeable to supply geospatial information service widely. China has paid great attention to construct the Digital China Geospatial Framework (DCGF). This NSDI has four layers at National, Provincial, Municipal and County level. DCGF has five components: data sets, technology, legal support and standards, coor...

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...

GeoBrain is a standard-compliant, open, distributed, three-tier Web information and knowledge building system developed for helping education and research activities in Earth system and geospatial information sciences. Utilizing latest Web service and knowledge management technologies, the system creates an on-line geospatial data-rich learning and research environment that enables students, fa...

Incomplete information has been studied in-depth in relational databases and knowledge representation. It is also an important issue in Semantic Web frameworks such as RDF, description logics, and OWL 2. In [6], we introduced RDF, an extension of RDF for representing incomplete information using constraints. We defined a semantics for RDF and studied SPARQL query evaluation in this framework. G...
