| 摘 要： | 海图上的水深具有以点代面的特殊性质,不仅是影响载负量的关键,而且水深点的不同形态和密度又是海底地形特征的反映。因而,只有经过海底地形特征的识别,同时参照海底地形的综合原则,才能实现水深综合的自动化。

| Abstract: | As a main part of nautical chart generalization,sounding generalization is also one of the bottlenecks in the ways of automatic chart generalization.Submarine topography is mostly represented by sounding on chart,to some extent,generalization of chart mainly means sounding selection.With the aid of Delaunay triangulation,the information,which contains the topology,distribution character,distribution density,can all be gained. |

| Keywords: | digital chart sounding distribution automatic generalization |
