【摘要】：利用多波束测深系统、三维激光扫描系统和无人机航摄系统,结合4S技术和云计算平台构建了海陆空大数据测绘系统,实现了海陆空三位一体化测量和大数据的快速处理、分析和管理。结果表明:海陆空大数据测绘系统在数据采集、处理、分析和管理方面具有传统测绘系统无法比拟的优势,提高了测绘效率,实现了陆地水下地形三维一体化无缝拼接和陆地水下三维一体化漫游,真实地再现了陆地水下的三维虚拟场景,拓宽了应用领域,生成了多样化的地理信息成果;实现了测绘产品的再利用,通过研究分析测区的地形变化情况,可及时掌握陆地水土流失的趋势和河道冲淤变化程度,更好地为测区水土保持、河道管理提供基础性的依据,掌握了系统的数据处理和基于4S技术的河道地形演变分析方法。
[Abstract]:Using multi-beam bathymetric system, 3D laser scanning system and UAV aerial camera system, combined with 4S technology and cloud computing platform, a sea, land and air big data mapping system is constructed, which realizes the integrated measurement of land, sea and air and the rapid processing of big data. Analysis and management The results show that the sea, land and air big data surveying and mapping system has unparalleled advantages in data acquisition, processing, analysis and management, and improves the efficiency of surveying and mapping. The 3D integration of land and underwater terrain is realized, and the 3D integration of land and underwater is realized. The 3D virtual scene of land and underwater is reproduced truthfully, the application field is widened, and various geographic information results are generated. The reutilization of surveying and mapping products is realized. By studying and analyzing the topographic changes of survey areas, the trend of soil and water loss on land and the change degree of river erosion and siltation can be grasped in time, and the basic basis for soil and water conservation and river course management in survey areas can be better provided. Master the data processing of the system and the analysis method of river channel terrain evolution based on 4 S technology.
