摘　　要：对地图分区域构图特点进行了研究,结合嵌入式电子地图数据组织与图形特点,提出了一种集成行程长度与多段扫描转换算法的高效绘线方法,利用地图格网索引技术对算法进行了集成,验证了算法的效率。This paper attempts to study map composition characteristics of reigns with different terrains. Combined with data organization and graphic characteristics of embedded electronic map,an efficient line drawing method integrated with run-length and multi-scan conversion algorithm is proposed. The efficiency of the algorithm is verified by system integration with map grid index technology.
