EXPERIMENTS TO LOCATE RIDGES AND CHANNELS TO CREATE A NEW TYPE OF DIGITAL ELEVATION MODEL

Abstract

There have been numerous proposals to combine the advantages of the adaptability of the contour digital elevation model with the neighbourhood functions of the grid. Notable among these is the triangular irregular network model (TIN). This paper presents another approach to digital elevation modelling based on traces of channels and ridges, and other information-rich lines that may be identified on a surface.
