摘要
随着城市的发展建设、扩张以及改造,城市空间数据不断地发生变化,城市空间数据库需要及时更新。加强城市基础空间数据的更新管理,及时对城市空间数据进行测绘更新,才能保证城市基础空间数据的时效性和可用性,为城市的规划建设和管理提供全面、准确的基础资料。本文主要讲述了空间数据更新流程和更新方法,为实现空间数据库及时、快速、准确地更新提供技术支撑。
With the development and construction of the city, cities are expanded and transformed, urban spatial data are changed day and night. Therefore spatial database of city need to be updated timely, we must strengthen the management of spatial data, survey and update it timely, to ensure that the urban spatial data is realtime and available; to provide basic, comprehensive and accurate data for city planning and construction. This paper provides the process and methods of the spatial data update, and give a technical support to ensure that the spatial data can be updated timely, rapidly and accurately.
