数字地图符号的识别和推理验证

The recogition of Digital Map Symbols and its Inference and Examination

本文根据地图要素的形态分离结果，通过相互间几何关系与拓扑关系的建立，以图论为基础，重点论述了水深符号的识别、等深线值的自动标注和形态分离与识别结果的推理验证。

According to the morphological separate results of map elements. by means of their geometrical and topological relationship established and on the basis of the graph theory. this paper emphatically describesthe recognition of water depth symbols, the automated labeling isobathic line. and the inference and examination of morphology separate and recognition results.
