摘要
通过搭载单波束测深仪的无人测量船,辅助CORS系统和姿态仪,对长安新区滩涂区进行无验潮模式水下地形测量,建立了滩涂区水下地形DTM模型和水下3D模型。同时,依据测区设计标高,计算填挖土方量,为长安新区滩涂区造陆工程和城镇建设发展提供科学的测量成果并辅助决策。
Through unmanned ship with the instruments of single beam echo sounder, CORS system, attitude indicator,the underwater terrain was surveyed by hydrographic surveying model without traditional tide observation in Chang＇an new district. In the meanwhile, the DTM and 3D model were built up and calculated the excavation and filled volume, which provided a decision support for city construction and development.
