GEOCROWD Workshop 2014

3rd ACM SIGSPATIAL International Workshop on Crowdsourced and Volunteered Geographic Information 2014


In conjunction with ACM SIGSPATIAL 2014

Workshop website: http://www.geocrowd.eu/workshop_2014/


  • Submissions due: September 3
  • Notification: September 27
  • Camera-Ready Copy: October 7
  • Workshop: November 4


Following the successful workshops in 2012 and 2013, we are looking forward to organizing this third edition of the event, again in conjunction with the ACM SIGSPATIAL GIS conference (http://sigspatial2014.sigspatial.org).

The Internet, mobile and sensor revolutions continue to generate new data and data types, new uses of data, as well as new applications. At the same time, the equations of the data economy are being redefined as authorities continue to open up further their data repositories, whilst at the same time individuals and online communities are generating valuable data and are increasingly making them publicly available. Much of the generated data has a prominent geographic footprint, and this explosion of such volunteered geographic information (VGI) amounts to a massive expansion in our ability to digitize the world.

The domain that we aim to address in the workshop has been characterized by terms such as “geographic information retrieval,” “crowdsourcing,” “geospatial (semantic) Web,” “linked geospatial data,” and the “GeoWeb 2.0.”

This workshop aims at bringing together researchers and practitioners from the above areas to discuss open research problems and to develop a research agenda for the future. This workshop will 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 interest in relation to VGI (including but not limited to):

  • Data models and ontologies
  • Uncertainty and user-generated geospatial content
  • Quality control and assurance
  • Models of crowd engagement and crowd peer review
  • Geospatial data fusion techniques
  • Feature typing and tagging schemas
  • Privacy and confidentiality
  • Provenance
  • 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 incl. Natural Language Processing
  • VGI authoring techniques and tool support
  • The crowd and its relation with science
  • Crowd-based urban monitoring and design
  • Web applications for the collection and provision of VGI
  • Geometric algorithms
  • 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.
