Since OpenStreetMap (OSM) appeared more than ten years ago, new
collaborative mapping approaches have emerged in different areas and have become
important components of localised information and services based on localisation.
There is now increased awareness of the importance of the space-time attributes of
almost every event and phenomenon. Citizens now have endless possibilities to
quickly geographically locate themselves with an accuracy previously thought
impossible. Based on these societal drivers, we proposed a number of collaborative
mapping experiments (“mapping parties”) to delegates of a large open-source
geospatial conference and to citizens of the conference’s host city during July 2015.
