Abstract
In order to improve the sharing degree of big data and solve the pain points that are unwilling to share and can not be shared, cross-agency analysis and research should be carried out. Aiming at the construction characteristics of Geo-spatial big data, the main problems and solutions in Geo-spatial data sharing were analyzed. Starting from the management system, technical standards and physical architecture, a big data cross-agency sharing scheme was proposed. Then the quality of 3D building model data were evaluated . The results showed that constructing systematic cross-agency sharing solution will be helpful to promote the rational, standardized and efficient application of Geo-spatial big data.
