摘要
针对多波束测深数据集,采用改进的距离反比权重算法和多细节层次模型技术来建立海底数字地形模型(DTM)。结果表明:本方法具有较高的精度和效率,可以满足不同分辨率要求的DTM应用。
In this paper, we discuss a method based on inverse distance weighted (IDW) algorithm to construct seafloor digital terrain model (DTM) using multi-beam soundings, and the application of level of details(LOD) technology. It can draw the conclusion that DTM constructed by this method and managed by LOD is more accurate and more efficient than ordinary IDW.
