An Auto Proofreading Algorithm of Geographic VectorMap
矢量地图的一种自动校正算法

This paper describes an algorithm in the view of system identication and optimization about how to proofread a digital map in the form of vectormap. As it needs few sampled points and has high speed and enough precision, it is very practical. Finally it was used in the proofreading of Hefei geographic vectormap and satisfied results have been gotten.
