摘要
分析了外业航测及内业处理的流程,共布置了6个架次,得到了河道的正射影像、数字表面模型及数字线划图,精度校核满足1∶1 000比例尺的要求。实践表明,航测成果应用在河道境界划定及生态普查方面,有助于及时了解开采现状、合理安排生产计划,同时也可用于不同规格砂石的调配及现场安全监管工作,极大地提高了施工管理效率。
The article analyzes the process of field operation and internal processing,arranges six sorties,and obtains the orthophoto,digital surface model and digital line drawing of the river.The accuracy check meets the requirements of 1∶1000 scale.The practice shows that aerial survey results in the delimitation of river boundary and ecological census helps to understand the mining status in time and arrange the production plan reasonably.At the same time,it can also be used for the allocation of sand and gravel of different specifications and on-site safety supervision,which greatly improves the efficiency of construction management.
