Vienna, Sep 2014


A COST Action working group meeting was held in Vienna on 22-23 Sept 2014, organized by Cidália Fonte (PT), Linda See (AT) and Paolo Fogliaroni (AT). The meeting was originally focused on progressing the work of Working Group 4 on quality issues related to VGI. It was then decided to broaden the meeting to include an additional focus on the development of protocols across all WGs more generally. Based on feedback from the rapporteurs (Castellon, 6 Jun 2014), general feedback from COST members and the successful format of the Athens meeting, we asked participants to give a presentation on their VGI-related work and how this relates to the development of protocols and best practice guidelines.

This meeting was designed to help progress the following outcomes/deliverables as outlined in the DOW for COST Action TD1202:

  • Protocols for data storage and dissemination, disseminated by a range of publication routes
  • Documents outlining the best and good (acceptable) practices for VGI use in map production and evaluation, disseminated in a variety of ways targeted to specific audiences.

Meeting Agenda

A preliminary meeting was held at IIASA on 21 Sep to begin discussions and consider areas for collaboration. The formal meeting then took place on 22-23 Sep 2014, as outlined below. Presentations are available from the links below.

There were 20 participants from 12 EU countries who participated in the meeting. Of the 20 participants, 7 are Early Stage Researchers.

Meeting Outcomes

Based on ideas that were gathered during the course of the meeting, there were distinctive themes that emerged. Groups were formed around these themes and plans were made to progress the protocols/best practice guidelines/additional research as follows:

  • Environmental sensing / protocols: Kostas Karatzas, Paule-Annick Davoin, Lucy Bastin, Matej Nikšič, Andrea Pődör, Jari Silander
  • Protocols for photos: Linda See, Jacinto Estima, Cidália Fonte, Marco Minghini, Peter Mooney, Antoniou Vyron
  • Land cover/land use: Cidália Fonte, Jamal Jokar Asarjani, Linda See, Lucy Bastin, Jacinto Estima, Flavio Lupia, Grega Milcinski
  • Vector data protocols / OSM: Peter Mooney, Mari Laakso, Marco Minghini, Ana-Maria Olteanu Raimond, ‎Andriani Skopeliti, Antoniou Vyron
  • Data quality paper /uncertainty paper comparing Dempster-Shafer, Probability, Fuzzy and Possibility based approaches: Lex Comber, Cidália Fonte, Giles Foody, Steffen Fritz, Ana-Maria Olteanu Raimond, Carl Salk, Linda See

We agreed that shared documents would be created to advance the work and regular Skype calls would be held between theme members. It was also agreed which conferences would be targeted over the next year and the subject of the abstracts.

Future Activities

The next working group meeting to discuss protocols and best practices for collecting VGI will take place in Nice, April 2014. More details to follow on the main website.
