摘要
新规范标准首次明确了3种大比例尺(1∶500、1∶1 000、1∶2 000)的新图幅编号下的经纬度分幅标准,将经纬度分幅贯穿应用于11种常用比例尺中,但新规范标准并没有将旧图幅编号规则延续下来并应用于以上3种大比例尺中,本文先通过论述新旧图幅号编号规则,然后尝试将旧图幅编号规则应用于以上3种大比例尺中,这样使得新旧图幅规则全部应用于11种比例尺中,最后编程予以实现。
The new standard specifications of topographic map' s sheet number have first defined three kinds of large -scale maps (1 : 2000,1 : 1000,1 : 500) , which using latitude and longitude for new rules of sheet number, and applies different eleven scale maps, but the new specifications have not give the old sheet number regulation, this paper discuss the old and new rules of sheet number, and try to give the three large-scale map' s old sheet number, and make all of different eleven scale maps through both new and old sheet numbers, Finally, makes a programming with successful.
