如何维护更新数据是“数字城市”建设中面临的重要问题，而构建基于同源基本大比例尺数据连续化生产序列小比例尺数据，对多尺度城市空间数据进行纵向一体化管理的软件平台成为数据更新维护的关键。研究以基于同源数据的序列比例尺地图综合缩编平台建设为对象，主要从地图综合知识库形式化表达、地图综合流程决策控制机制、构建开放式地图综合软件系统构架体系、高效地图综合算子设计等方面进行重点阐述。此研究建设的软件平台已在广州市大型多尺度空间数据库快速构建中得到成功应用。

T he critical problem in digital city construction is how to update the multi‐scale spatial data timely and consistently .This paper purposes a software platform of sequence scale map generation based on the same basic large scale data ,w hich can also provide unified and longitudinal vertical management of multi‐scale data .The study includes three main parts .Firstly ,it sets up a six‐element formal expression of map generation rules ,and then builds a five‐factor control mechanism of map generation process .Secondly , it constructs a open system architecture for the software platform of sequence scale map generation . Thirdly ,it studies a series of applicable and efficient map generation algorithms considering the unique geographical features in Guangzhou city .The software platform has been successfully applied to the rapid building of multi‐scale spatial database in Guangzhou City .
