多源异构数据构建技术在水利三维测绘中的应用研究
Research on the application of multi-source heterogeneous data construction technology in three dimensional surveying and mapping of water conservancy
摘要
Abstract
In view of the problems of low data collection efficiency,the quality and accuracy of the generated data results are difficult to meet the requirements,and the independent data are difficult to effectively integrate with each other,the key technologies involved in the construction method of multi-source heterogeneous data are studied,and the rapid measurement of the terrain within the survey area can be realized through airborne Lidar,ground handheld laser scanner,and multi/single beam system,and high quality multi-source heterogeneous data such as air-space-ground,underwater images and point clouds can be obtained.For onshore and underwater point cloud data,the classification of ground point clouds and the generation of water and land are carried out.The multi-source heterogeneous data results are integrated,the multi-source heterogeneous database is constructed,and the three dimensional WebGIS data management system platform is developed to display and apply the data results,which realizes the comprehensive management of multi-source heterogeneous data,which is of great significance for the construction,utilization and maintenance of rivers,lakes and water conservancy projects,and also paves the way for the establishment of the data base standard system,and plays a promoting role in the construction and management of digital twin water conservancy projects,rivers,lakes and water conservancy projects.关键词
