Querying VGI by semantic enrichment [chapter]

Rob Lemmens, Gilles Falquet, Stefano De Sabbata, Bin Jiang, Benedicte Bucher
2016 European Handbook of Crowdsourced Geographic Information  
Volunteered geographic information (VGI) plays an increasing role in current geodata provision.  ...  We describe the characteristics of semantic enrichment and explain how folksonomies and ontologies play a role.  ...  Towards semantic queries In this section we show the different uses of semantic enrichment when querying a VGI source.  ...

Semantic Enrichment of Geographic Data and 3D Models for the Management of Archaeological Features [article]

Achille Felicetti, Matteo Lorenzini, Franco Niccolucci
2010 VAST: International Symposium on Virtual Reality  
We propose a possible way to integrate 3D data in a geographic environment and in addition to enrich 3D models by providing a set of semantic descriptions for each geometrical component of a given object  ...  The same difficulties occur when it is necessary to link geographic information to 3D models or to deal with metadata and annotations concerning the same elements, for which semantic technologies are required  ...  In recent years we have already oriented our research towards the integration of geographic data and archaeological excavation records stored in relational databases by "enriching" them with semantic information  ...
