摘　　要：基础性地理国情监测和1∶50000地形数据更新项目均已成为常态化生产项目。本文在两个项目的资料源、技术要求、内容指标、工艺流程等方面开展对比分析,总结梳理二者的异同点,挖掘两个项目的共性地理要素,研究和试验两个项目协同更新生产模式。研究结果表明,在资料收集与共享利用、内业协同采集、外业协同调绘方面可以进行不同程度的协同,可为后续两个项目开展协同更新生产提供技术解决方案。The fundamental geographical national monitoring data and the 1∶50000 scale national topographic data have now been regularly produced by surveying and mapping departments.This study summarizes the similarities and differences between the two data,in terms of data sources,technical requirements,indicators and workflows.We primarily focused on the common geographical elements shared by the two data and investigated the mode for collaborative production of the two data.The research indicates that the two projects can be collaborative production at different levels,in terms of data collection and sharing,collaborative collection,and field collaboration.The study provides technical solutions to future production of the two data in a collaborative mode.
