地形图符号 meaning in Chinese
topographic legend
topographic map symbol
topographic symbols
Examples
- Branch system is simply designed too . at last , point symbol achieved has tested with image match . lt will improve a reference for topographic map pattern automatic recognization , it has significance of theory and practice
并通过影像匹配法对地形图符号获取进行了初步实验。为进一步实现地形图模式识别自动化开发提供参考，具有一定的理论意义和实用价值。 - Recognization and extraching digitized geo - information from map image opens a new way for map digitization and it is achieved signaficant for geographic information constuction and application . in this paper , the following four aspects are explored and discussed . ( 1 ) topographic map scanned is pre - settled for facing automatic recognization , it includes option of binary image , elimination of noise , thinning of symbols , modificatoin of intermittent points and deletion of error ect
本文从这个角度出发，基于对地形图自动模式识别获取信息和数据，从四个方面进行了研究和探讨： ( 1 ) 、面向自动识别扫描地形图数据预处理内容研究，包括二值化阈值选取、地形图的噪声消除、地形图符号的细化、细化后的断点修补和毛刺的剔除等。 - According to concept of logic and geometrical shape of symbols the represented categories of geographic concepts and their mutual relationships on the basis of symbols of topographic maps are defined and the actual examples are given , which provides for reference meaning for studying cartographic language by logic method
根据逻辑学概念和符号的几何形状，定义了基于地形图符号表达的地理概念的种类及其相互关系，并给出具体实例，为用逻辑方法研究地图语言提供了借鉴意义。 - In order to solve the problem of symbolic representation in geographic concepts and their mutual relationships , the geometrical composition of symbols of large scale topographic maps and the semantic and geometrical relationships among symbols are analyzed , the symbols system of topographic maps is regarded as a two - dimensional graphic language , and the relationship between symbols and geographic concepts is discussed
摘要为了解决地理概念及其相互关系的符号化表达问题，分析了大比例尺地形图符号的几何构成及符号间的几何和语义关系，把地形图符号系统作为一种二维图形语言，讨论了它和地理概念之间的关系。
