数字经济下对新型基础测绘数据的时效性要求越来越高，如何低成本实现快速动态更新已是当前亟待解决的痛点。针对工程建设项目“多测合一”生产需求与基础地理实体数据及数据库关系，研究了以“多测合一”驱动更新基础地理实体数据库的关键技术。通过分析基础地理实体数据库的特点以及工程建设项目“多测合一”对底图数据的需求，在统一基础地理实体数据库结构与“多测合一”数据标准下，借助信息化手段建立底图数据“库中来库中回”的工作流程，提出了一种一测多图、变化检测和驱动更新的方法。该方法能够保持基础地理实体数据库的现势性，并实现“多测合一”项目成果对基础地理实体数据库的有效更新，避免重复测绘。

In the era of digital economy, there is an escalating demand for the timeliness of new fundamental surveying and mapping data, and the challenge of achieving rapid and cost-effective dynamic updates has emerged as a pressing issue. According to the technical essentials of update fundamental geographical entity databases driven by “Multiple Measurement in One” project, considering the operational requirements of projects and the characteristics of fundamental geographical entity data elements along with their database relationships, we proposed a“loop from and back to the database”workflow for basic map data update, under a unified structure of fundamental geographical entity databases and the“Multiple Measurement in One”data standards. This approach utilizes information technology to enable a single survey to generate multiple maps, change detection, and database update. Consequently, it maintains the currency of fundamental geographical entity databases, efficiently incorporates the“Multiple Measurement in One”project outcomes into database updates, and mitigates the need for redundant surveying and mapping activities.
