摘　　要：本文基于全球测图项目,对林地区域DSM、DEM传统数据制作流程存在的问题进行了分析,找出制约生产效率的瓶颈,结合生产实践,提出基于PhotoMap软件结合影像数据自动提取林地边界的解决方法,经过生产检验与传统作业的对比达到了预期的效果,为以后的测绘项目生产提供作业思路,积累了宝贵经验。Based on the global mapping project,this paper analyzes the problems existed in the traditional data-making process of DSM and DEM in forest areas,finds out the bottleneck of production efficiency.Combined with the production practice,this paper puts forward a method of automatically extracting forest land boundary based on PhotoMap software and image data,which achieves the expected effect through production test and provides the operation idea for the future production of surveying and mapping projects,and accumulates valuable experience.
