摘　　要：常规的地理信息系统数字化地图制图要素分类编码方法主要使用attribute\\property内外部要素提取法调整编码几何映射状态,易受用户属性扩充作用影响,导致编码性能指标低下,因此,提出了一种地理信息系统数字化地图制图要素分类编码方法。即设计数字化地图制图要素分类编码框图,构建数字化地图制图要素分类编码符号库,从而完成地理信息系统数字化地图制图要素分类编码。实验结果表明,设计的数字化地图制图要素分类编码的性能指标良好,具有较高的应用价值,为满足地理空间信息数字化分析处理的需求作出了一定的贡献。The conventional mapping element classification and coding method of digital maps in geographic information systems mainly uses attribute\property internal and external element extraction method to adjust the coded geometric mapping state,which is susceptible to the effect of user attribute expansion,resulting in low coding performance index.This paper presents a method of classification and coding of mapping elements of digital maps in geographic information systems.In other words,the classification and coding frame diagram of mapping elements of digital maps is designed,and the symbol library of mapping elements of digital maps is constructed,so as to complete the classification and coding of of mapping elements of digital maps in geographic information systems.The experimental results show that the performance indicators of the designed digital map mapping element classification and coding are good and have high application value,making a certain contribution to meeting the digital analysis and processing of geographic spatial information.
