RoadPlex: A mobile VGI game to collect and validate data for POIs


Kashian, Alireza; Rajabifard, Abbas; Richter, Kai-Florian (2014). RoadPlex: A mobile VGI game to collect and validate data for POIs. In: ISPRS Technical Commission II Symposium, Toronto (CA), 6 October 2014 - 8 October 2014, 55-60.

Abstract

Because of increasing popularity of smart phones equipped with GPS sensors, more volunteers are expected to join VGI (Volunteered Geographic Information) activities and therefore more positional data will be collected in shorter time. Current statistics from open databases such as OpenStreetMap reveal that although there has been an exponential growth in the number of contributed POIs (Points of Interest), the lack of detailed attribute information is immediately visible. The process of adding attribute information to VGI databases is usually considered as a boring task and it is believed that contributors do not experience a similar level of satisfaction when they add such detailed information compared to tasks like adding new roads or copying building boundaries from satellite imageries.
In other crowdsourcing projects, different approaches are taken for engaging contributors in problem solving by ‘hiding’  the tasks behind a  game.  In  the  literature,  this  concept  is  known  as  “gamification”  or  “games  with  purpose”  which  encapsulate  the  idea  of   entertaining contributors while they are completing a particular defined task. The same concept is used to design a mobile application  called  “RoadPlex”  which  aims  to  collect  attribute information for POIs.
The increased number of contributions in the past few months confirms that the design characteristics and the methodology of the game are appealing to players. Such growth enables us to evaluate the quality of the generated data through mining the database of answered questions. This paper discusses some contribution results and emphasises the importance of using gamification concepts in the domain of VGI.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
