Geospatial data is vitally important to the ways thousands of government agencies, private companies and non-profit organizations do their businesses. The widespread access and sharing of geospatial data on the Internet yield many benefits. But, there are two important barriers in front of sharing and accessing geospatial data; non-interoperability and insufficient message exchange patterns of ...

Huge volumes of geospatial data have been collected by both public and private sectors. In order for the geospatial data to be useful, information has to be extracted from the data and converted to knowledge. However, currently it is very difficult for most of users to obtain the geospatial data and to turn them into useful information and knowledge. In order for geospatial information and know...

Producing and updating geospatial data is expensive and resource intensive. Hence, it becomes crucial to be able to integrate, repurpose and extract added value from geospatial data to support decision making and management of local, national and global resources. Spatial Data Infrastructures (SDIs) and the standardisation efforts from the Open Geospatial Consortium (OGC) serve this goal, enabl...

Linked geospatial data has recently received attention as researchers and practitioners have started tapping the wealth of geospatial information available on the Web. With the rapid population of the Web of data with geospatial information, applications to manage it have also started to emerge. What the semantic geospatial web lacks, though, compared to the technological arsenal of the traditi...

This paper situates geospatial technologies as a constructivist tool in the K-12 classroom and examines student experiences with real-time authentic geospatial data provided through a hybrid adventure learning environment. Qualitative data from seven student focus groups demonstrate the effectiveness of using real-time authentic data, peer collaboration, and geospatial technologies in learning ...

Digital curation is a new term that encompasses ideas from established disciplines: it defines a set of activities to manage and improve the transfer of the increasing volume of data products from producers of digital scientific and academic data to consumers, both now and in the future. Research topics in this new area are in a formative stage, but a variety of work that can serve to advance t...

Geospatial metadata, data, and services have been widely collected, developed and deployed in recent years. This flourishing of geospatial resources also added to the problem of geospatial heterogeneity. Interoperability research and implementation are needed for advancement in potential solutions to integrate and interoperate these widely dispersed geospatial resources. We design and implement...

1082-4006/05/1101-24$5.00 ©2005 The International Association of Chinese Professionals in Geographic Information Science (CPGIS) Abstract This paper discusses an interoperable system framework for developing web-service-based intelligent geospatial knowledge systems. This type of systems facilitates personalized, on-demand geospatial information or knowledge discovery and dissemination. The sys...

As geospatial data are becoming more widely used through mobile devices and location sensitive applications, the potential value of linked open geospatial data in particular has grown, and a foundation is being developed for the Semantic Geospatial Web. Protocols such as GeoSPARQL and stSPARQL extend SPARQL in order to take advantage of spatial relationships inherent in geospatial data. This pa...
