摘要
Abstract
In this paper,the Gaussian weighted average algorithm is proposed to grid efficiently the discrete multi-beam data. That results in preserving the small terrain features and the faster convergence of the weight function. And then,a mapping method,which recommends 2D contour chart overlaying with the 3D shaded relief map, can achieve the final results of a good perspective and fine details of the terrain. Finally, how to improve the color schemes of the bathymetric chart is discussed.关键词
