摘要
采用固定航高摄影测量方式生成高山地区大比例尺地形图,存在局部区域精度无法满足1:2000精度要求的问题.针对此问题,笔者在分析固定航高摄影测量方式特点和不足的基础上,提出了采用仿地飞行摄影测量技术生成高山地区大比例尺地形图的作业方案.实际测试表明,采用该方案生成的地形图,其精度均匀,可满足高山地区1∶2000测绘精度要求.
Abstract
The large scale topographic map of high mountain area is generated by fixed aerial height photogrammetry,but the accuracy of some areas cannot meet the requirement of 1:2000 accuracy.In order to solve this problem,based on the analysis of the characteristics and short-comings of the fixed aerial height photogrammetry method,the author puts forward the opera-tion scheme of generating large scale topographic map in the high mountain area with the imita-tion flying photogrammetry technology.The actual test shows that the topographic map genera-ted by this scheme has uniform accuracy and can meet the requirement of 1 ∶2000 mapping ac-curacy in alpine area.
