Development of an update procedure for autoritattive spatial data by the combination with crowdsourced information

---

The demand for up-to-date spatial data is growing very high in this rapidly changing world. Updating the autoritative spatial data is not always associated with the updating of well established existing spatial data, but it can be extended into the additional collection of new specific themed spatial data. Unforunately, authorities who produce golden standard spatial data cannot fill those needs. Considering the merits that VGI can give to fill the gap between demand and supply in authoritative data update, an conceptual framework for authoritative data update using VGI data is proposed. The advantage of the proposed framework is its flexibilities that includes: customizable quality assessment modules; flexible assembly and placement of the quality modules; flexible workflow starting point; and the flexible weighting factor. Based on the framework, three scenarious are made; updating authoritative data with VGI, new theme adoption, and generating thematic information from VGI data. The updating of autoritative data with VGI is implementeed to test the feasbility of the framework. The implementation result shows that the current OSM data cannot surpass the superiority of older RBI data, especially in positional and thematic accuracy. Despite the usability output cannot be used for update, it can be use as the change detection indication that will help autorities to plan the updating processes effectively. Moreover, the implementation proves that automation of the framework is doable and consequently the update frequency could be improved.
