基于不完全四叉树的数字水深模型多尺度表达
Multi-scale Representation of Digital Depth Model Based on Unfull Quatree
摘要
Abstract
The multi-scale representation of spatial data is one of the most important and difficult problems in the field of GIS.This paper focuses on the multi-scale representation of Digital Depth Model (DDM,grid) and the geometric character of DDM,and constructs a multi-scale representation model of DDM based on the unfull quatree.The experiments show that this model can preserve the basic characters of the DDM with high computing efficiency.关键词
