摘　　要：针对地形要素内外业更新的一体化无缝衔接问题,设计并实现了基于数据库增量更新的数字外业巡查系统。采用数字外业巡查系统,较好地解决了1∶50 000地形数据库重点要素每年更新一次与传统纸质外业调绘作业模式的矛盾,适应了地理空间数据多元化、高效性的社会需求,实现地形要素内外业更新的真正一体化无缝衔接。基于1∶50 000地形数据库动态更新项目的实际应用情况证明:系统贴合生产紧密,运行效率高,程序流畅,操作简单,得到用户和专家的一致认可,对地理空间要素的快速动态更新、内外业作业流程、外业调绘产品模式等研究与应用具有一定的参考价值。In recent years, it has been increasingly important to update the 1 ： 50 000 topographic database annually to meet the requirements of geospatial data diversity and effectiveness. However, the annual updating poses several challenges, including the conflict between the annual updating and the traditional paper-based filed survey and the challenge of true seamless connection between field survey and digital survey. To tackle these challenges, we developed and implemented a digital field inspection system based on the database incremental updating. Experimental results show that the system runs smoothly and has significant performance, moreover, the system provides a friend and convenient interface for end users. Therefor, the system has gained recognition from both users and experts. The research and mechanisms used in the system provide valuable insight into the fast and dynamic updating of geospatial feature, the optimization of digital mapping and field survey workflow and the further research of field survey products.
