Location and Dates
- November 6, 2012
- Redondo Beach, CA, USA
In conjunction with ACM SIGSPATIAL 2012 (Nov. 6 – 9, 2012)
With the proliferation of the Internet as the primary medium for data publishing and information exchange, we have seen an explosion in the amount of online content available on the Web. Thus, in addition to professionally-produced material being offered free on the Internet, the public has also been allowed, indeed encouraged, making its content available online to everyone. The volumes of such User-Generated Content (UGC) are already staggering and constantly growing. Here, our goal has to be to take advantage of this explosion in Volunteered Geographic Information (VGI), which applied to the geospatial domain translates to massively collecting and sharing knowledge to ultimately digitize the world.
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”, “Crowdsourcing”, “Geospatial (Semantic) Web”, “Linked Geospatial Data”, “GeoWeb 2.0” etc.
This workshop aims at bringing together researchers and practitioners from the above areas to discuss open research problems and develop a research agenda for the future. This workshop should also serve as a common platform for the exchange of ideas and results coming from existing research initiatives and projects in the US and Europe that currently investigate this topic.
Topics of Interests
Topics of interest in relation to VGI (including but not limited to):
- Data models and ontologies
- Uncertainty and user-generated geospatial content
- Quality control and assurance
- Geospatial data fusion techniques
- Feature typing and tagging schemas
- Privacy and confidentiality
- Synthesis of multi-source data (broader than conflation)
- Analysis of multi-source data
- Data management and VGI incl. data stream management and mobile computing
- Spatial reasoning and analysis
- Data extraction techniques including NLP
- VGI authoring techniques and tool support
- Web applications for the collection and provision of VGI
- Computing/algorithms and geospatial uncertainty
- Crowdsourcing computing resources
- Non-traditional visualization techniques
Authors are invited to submit full, original, unpublished research papers that are not being considered for publication in any other forum. Manuscripts should be submitted in PDF format and formatted using the ACM camera-ready templates available at
Submissions are limited to 8 pages. All submissions will be refereed for quality, originality, and relevance by the Program Committee. Accepted papers will be considered for a special issue in a respective scientific journal.
Submissions should be uploaded through the submission site at:
At least one author per accepted paper must register and attend the workshop to present the accepted submission. Otherwise, the accepted submission will not appear in the published proceedings or in the ACM Digital Library version of the proceedings. All questions should be addressed to the organizers.
