Collaborative Update of Geographical Information Services Using Crowdsourcing Mode
摘要
Abstract
Aiming at the low update frequency of geographical information service,we proposed a collaborative update method based on"crowdsourcing collection,organization and database collaboration".The method integrated various change monitoring methods to mine various types of geographical information,used the crowdsourcing organization method to incorporate geographical information enterprises into the inte-grated geographical information service collaborative update system,connected the base spatial database with the industry databases through the distributed network,detected the current situation of industry database through the heartbeat line,and realized the collaborative update of geographical information services across regions,departments and industries.The practice of"MapWorld Guangxi"shows that the method can break through the traditional centralized operation mode,and give full play to the advantages of networking,localization and fragmented crowdsourcing organization collection.Meanwhile,the rolling update cycle of geographical information service is shortened year by year,and the"T+1"service update can be realized in key areas,which greatly improves the current situation of geographical information service.关键词
