摘要
提出了一种沿地图上等高线分段截取数据,建立数字地图的方法。规定了数字地图分区存放的数据结构。对应这种数字地图提出了双星定位计算的方法,以北京南郊400km^2范围作数字地图进行定位计算,结果表明定位算法简单快捷,数字地图有效并可节约存贮空间。
The paper describes a new method to establish digital map
efficiently by using contour.Data frame was designed to store digital map
data.A Positioning method correspondent to the digital map was developed
The position calculation was carried out in the digital map of 400km^2
area and the results illustrated that position method was simple and fast,
digital map was effective and could spare the memory space.
