摘要
为推进国民经济和城市大数据建设,城市政府各部门的地理信息资源不断丰富;但在推进信息化建设过程中出现了采用地图基准不同、更新不及时等问题,导致重复建设现象严重,数据难以融合、共享。通过对常熟市委办局各类多源矢量数据整合更新技术流程的研究,实现了统一的城市多源矢量电子地图更新,为常熟市地理信息规范化共享提供了基础数据支撑。
In order to promote the construction of national economy and urban big data,the geographical information resources of urban government departments are constantly enriched.However,in the process of promoting the informatization construction of various departments,there are some problems,such as using different map benchmarks and not updating in time.As a result,the phenomenon of repeated construction is serious,and the data are difficult to integrate and share.In this paper,based on the technical process research of integration and update of various kinds of multi-source vector data of Changshu Municipal Party Committee Office,we achieved the unified urban multi-source vector electronic map update,which could provide basic data support for the standardized sharing of Changshu geographical information.
