Abstract: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.
Keywords:multi-beam echosounding  digital terrain model(DTM)  inverse distance weighted(IDW)  level of details(LOD)
