This study presents results from an on-going social map service pilot that supports a national mapping agency (NMA) in data collection. Results from the pilot show that a VGI map service benefits both citizens and the NMA; the data quality is high enough to suit the needs of an NMA; citizens obtain a means to contribute and be involved in ameliorating maps. The social map service works also as a citizen-to-citizen communication channel as all the contributions are immediately visible to all users. Based on the results of this study, VGI should be further integrated with NMA processes in the future. One way of improving the integration are via services offered to both citizens and NMA employees that borrow features from existing social network services but also from popular games. Commenting, voting and gamification elements can be integrated with the VGI services to benefit both citizens and NMAs. Due to the numerous challenges of VGI the European national mapping agencies involvement in using citizens as data collectors is low. It is, however, within the NMA’s grasp to develop the role of VGI in NMA processes further and to make VGI collection fun.

Map Gretel：社交地图服务，在数据收集方面为国家测绘机构提供支持

这项研究提出了正在进行的社会地图服务试验的结果，该试验支持国家地图局（NMA）的数据收集。试点结果表明，VGI地图服务使公民和NMA受益。数据质量足够高，可以满足NMA的需求；公民获得了贡献并参与改善地图的手段。社交地图服务还可以作为公民与公民之间的交流渠道，因为所有用户都可以立即看到所有贡献。根据这项研究的结果，将来VGI应该与NMA流程进一步集成。改善集成的一种方法是通过向公民和NMA员工提供的服务来借鉴现有社交网络服务以及流行游戏的功能。评论，投票和游戏化元素可以与VGI服务集成在一起，以使公民和NMA受益。由于VGI的众多挑战，欧洲国家制图机构参与使用公民作为数据收集者的参与率很低。但是，进一步发展VGI在NMA流程中的作用，并使VGI收藏变得有趣，这是NMA的职责。
