摘要
多源底质点数据存在分布密度差异大、数据冗余度大等局限,现有的点状要素选取方法无法满足应用需求。在顾及点数据底质类型,确定底质分布域完成底质点分区,获得点群数据后,提出了基于动态圆增长模型进行底质点的选取方法。
Multi-source seabed sediment point data has many limitations, such as large density difference and data redundancy.The existing point selection method can not meet the application requirements. After taking into account the sediment type of point data and getting sediment distribution domain and point groups, we put forward a partition selection method of multi-source seabed sediment points data based on dynamic circular growth model.
