Special Issue Information

Dear Colleagues,

The steady rise of data volume shared on already-established and new Volunteered Geographic Information (VGI) and social media platforms calls for advanced analysis methods of user contribution patterns, leads to continued challenges in data fusion, and provides also new opportunities for rapid data analysis for event detection and VGI data quality assessment. Questions regarding the future of VGI and social media platforms include the prospect of continued user growth, engagement of new user groups, further expansion of VGI to educational activities, and closing data gaps in geographically underrepresented areas.

Although some papers for this Special Issue will be drawn from a related one day VGI-ALIVE workshop at the AGILE 2018 conference, other original submissions aligned with this area of research are also highly welcome. The workshop evolves around a wide range of VGI and social/media research topics including cross-platform data contributions, innovative VGI analysis approaches, current data fusion methods, data interoperability, real-world applications, and the use of VGI and social media use in education. Contributions that discuss future challenges of VGI and social media, may it be on the legal or technical side, that formulate a vision for VGI and social media usage and analysis for the near future, and that demonstrate analysis workflows or the integration of VGI into education are also welcome. This Special Issue offers an outlet for publishing papers relevant to the scope of this workshop. Papers will be reviewed on a continuing basis until the submission deadline.

Article processing fees of IJGI can be waived for a limited number of papers, where priority is given to papers presented during the VGI-ALIVE workshop at the AGILE 2018 conference and early submissions. Please contact the Guest Editors for more information.

Special issue topics include (but are not limited to):

  • Activity patterns and collaboration across multiple VGI and social media platforms
  • (Quasi) real-time analysis of VGI and social media content
  • Technical and legal aspects of crowd-sourced data fusion
  • Opportunities, challenges, and limitations for the future of VGI
  • VGI and social media analysis in geographic areas with sparse data coverage
  • Novel methods of VGI data quality assessment
  • Mobility patterns from VGI and social media
  • User engagement and VGI education
  • Closing the gaps in VGI data coverage

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. ISPRS International Journal of Geo-Information is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

OpenStreetMap (OSM) has proven to serve as a promising free global encyclopedia of maps with an increasing popularity across different user communities and research bodies. One of the unique characteristics of OSM has been the availability of the full history of users’ contributions, which can leverage our quality control mechanisms through exploiting the history of contributions. Since this aspect of contributions (i.e., historical contributions) has been neglected in the literature, this study aims at presenting a novel approach for improving the positional accuracy and completeness of the OSM road network. To do so, we present a five-stage approach based on a Voronoi diagram that leads to improving the positional accuracy and completeness of the OSM road network. In the first stage, the OSM data history file is retrieved and in the second stage, the corresponding data elements for each object in the historical versions are identified. In the third stage, data cleaning on the historical datasets is carried out in order to identify outliers and remove them accordingly. In the fourth stage, through applying the Voronoi diagram method, one representative version for each set of historical versions is extracted. In the final stage, through examining the spatial relations for each object in the history file, the topology of the target object is enhanced. As per validation, a comparison between the latest version of the OSM data and the result of our approach against a reference dataset is carried out. Given a case study in Tehran, our findings reveal that the completeness and positional precision of OSM features can be improved up to 14%. Our conclusions draw attention to the exploitation of the historical archive of the contributions in OSM as an intrinsic quality indicator. Full article
