LBCS projects are implemented as, for instance, locationbased games with the purpose to collect urban data (Celino et al, 2012), location-based services in cities (Bentley et al, 2014), local news platforms (Väätäjä et al, 2012), and geographic information for disaster response (Goodchild and Glennon, 2010) etc. While, in LBCS, the location of the crowdsourcer may be relevant or not, the location of a crowdsourcee is significant (Bauer et al, 2014).…”
