Vectorization of Linear Features in Scanned Topographic Maps Using Adaptive Image Segmentation and Sequential Line Tracking

Abstract

Vectorization of cartographic features is a difficult task in geographic information acquisition from topographic maps. This paper presents a semi-automatic approach to linear feature vectorization directly in original scanned colour topographic maps without layer separation. In the approach, a sliding window is added on a user-given linear feature, and the… (More)
