5th International Terra Cognita Workshop 2012
In Conjunction with the 11th International Semantic Web Conference
November 12, 2012
Boston, USA

Foundations, Technologies and Applications of the Geospatial Web


The wide availability of technologies such as GPS, map services and social networks, has resulted in the proliferation of geospatial data on the Web. In addition to material produced by professionals (e.g., maps), the public has also been encouraged to make geospatial content, including their geographical location and a record of their outdoor activities, available online. The volume of such user-generated geospatial content is constantly growing. Similarly, the amount of data extracted from the Web and published as Linked Open Data is increasing. Linked Open Data include many data sets with geospatial properties such as coordinates, feature classes or topological relations. Examples of such data sets are GeoNames.org, LinkedGeoData.org and DBpedia.org.

The geo-referencing of Web resources and users has given rise to various services and applications that exploit it. With the location of users being made available widely, new issues such as those pertaining to security and privacy arise. Likewise, emergency response, context sensitive user applications, and complex GIS tasks all lend themselves toward solutions that combine both the Geospatial Web and the Semantic Web.

Researchers have been quick to realize the importance of these developments and have started working on the relevant research problems, giving rise to new topical research areas such as Geographic Information Retrieval, Linked Geospatial Data, GeoWeb 2.0. Similarly, standardization bodies such as the Open Geospatial Consortium (OGC) have been developing relevant standards such as the Geography Markup Language (GML) and GeoSPARQL.

The workshop will bring together researchers and practitioners from various disciplines, as well as interested parties from industry and government, to advance the frontiers of this exciting research area. Bringing together Semantic Web and geospatial researchers helps encourage the use of semantics in geospatial applications and the use of spatial elements in semantic research and applications. The field continues to gain popularity, resulting in a need for a forum to discuss relevant issues.

Workshop Series

This is the 5th Terra Cognita workshop. The previous ones were:


This workshop is organized by members of the Spatial Ontology Community of Practice (SOCoP) and European project TELEIOS.

TELEIOS is an FP7/ICT project with the goal of building an Earth Observatory. TELEIOS concentrates heavily on geospatial data (satellite images, traditional GIS data, geospatial Web data).

SOCoP is a geospatial semantics interest group currently mainly with members from U.S. federal agencies, academia, and business. SOCoP’s goal is to foster collaboration among users, technologists, and researchers of spatial knowledge representations and reasoning towards the development of a set of core, common geospatial ontologies for use by all in the Semantic Web.
