CIScience Heidelberg members Dr. Tobias Törnros and Dr. Hongchao Fan attended the ISSDQ’15 (The 9th International Symposium on Spatial Data Quality) from 28 to 30 September 2015 in La Grande Motte, France. Tobias had an excellent talk about uncertainties of completeness measures in OpenStreetMap – A case study for buildings in a medium-sized German city. On behalf of the special session chairs (Prof. Dr. Alexander Zipf, Dr. Jamal Jokar Arsanjani, Dr. Mohamed Bakillah, Dr. Vyron Antoniou and Ahmed Loai Ali), Hongchao Fan from GIScience HD chaired a special session on quality analysis of Volunteered Geographic Information (VGI) towards effective use.
Approximately, 60 participants took part in the ISSDQ’15. 31 oral presentations were given by colleagues from more than 10 countries. In addition, there was a poster session with 15 posters. During the two-days event, the symposium participants presented and discussed methods, algorithms, and applications related to spatial data quality.
