Transformation of Data into a Raster-Scan Format and Some Image Processing Applications

摘要

An account is given of techniques that can be used to process and manipulate data that is in the form of either a series of contours or a set of unconnected points, so that it can be transformed into a digital raster-scan format. Two applications of this work are described; these are the deliberate degradation in the spatial resolution of contour maps and the use of terrain height information in conjunction with Landsat imagery. In the discussion of both these topics reference is made to programs available at the Remote Sensing Unit of Space Department, RAE. (Author)
