摘要
在完成海岛像控测量、野外调绘、空三加密、内业测图等航空摄影测量技术流程,测绘比例尺1∶10 000海岛地形图,制作相应的数字高程模型、正射影像图等产品的基础上,总结了航测技术应用于海岸、海岛地形测绘的技术方法、作业流程,并将航测成果与常规海岸地形测量成果进行比对,得出了航测成果精度能够满足《海道测量规范》要求,航测技术可以用于海岸地形测绘的明确结论。
Based on producing island topographical map,DEM and orthograph for scales of 1∶10000,following the processing of photo controls surveying,field annotating,aerotriangulating,stereomapping,this paper summarizes the technology and the process of photogrammetry used in littoral and island topographic survey.Comparing the results with old method of littoral topographic survey,this technology contents the ＂Specification for hydrographic survey＂,and can be used in the area of littoral topographic survey.
