摘要

An automated technique is described, for extracting lines from Landsat multispectral scanner (MSS) images by means of 'density contour' threading of the data. The resulting lines can then be transformed to fit any map system - in particular the British National Grid - with the aid of selected ground control points. The application of these techniques to the interpretation of Landsat imagery is discussed. (Author)
