Piloting a Map Service to Collect VGI for National Topographic Database
Mari Laakso, Mikko Ronneberg & Tapani Sarjakoski
Linked to the big renewal of the National Topographic Database (NTDB) the National Land Survey of Finland (NLS) wants to create a concept for the use of Volunteered Geographic Information (VGI) in the collection and update of the data for the NTDB. To test the concept, a pilot system is under development. In the pilot NLS provides a browser-based map service for citizens which enables data import and data editing. Some topographic data feature classes, such as hiking trails, have been selected to be in the focus during the pilot phase. The usability of the user interface (UI) in the map service has a major importance as the users don?t necessarily have any expertise in mapping or cartography. Therefore, the UI needs to be intuitive and guide the user through the process of contribution. All the contributions by users will be displayed publicly in the map service and are immediately available for everybody. Contributing users are required to register by creating an user account whereas anybody may view the contributed data. There are still open questions on how the data will be validated before transferring it to the operational NTDB. The map service for the pilot is currently at the development phase. Once the pilot use has started, the usage will no doubt reveal needs for improvement to the system. Eventually we hope to get experience-based information and understanding of the applicability of crowdsourcing methods to support the collection and maintenance of the NTDB content.
