On Shifting of Linear Feature

摘要: 制图综合常要求将地形图要素从其正确的图面位置偏移一点。本文就线状要素的移位问题进行讨论。首先提出移位场的概念,这对于由于移位所产生的"连锁反应"能较好地解决;然后,提出一种栅格探测——矢量计算方祛,加快移位计算的速度。

Abstract: In this paper,two kinds of problems are discussed. A method of rastor prospect-ing/vector caculating is presented,used to speed up shifting caculating. A concept aboutshifting -area is presened,used to explain "chain reaction" for shifting.
