Algorithms for the reduction of the number of points required to represent a digitized line or its caricature
TL;DR: In this paper, two algorithms to reduce the number of points required to represent the line and, if desired, produce caricatures are presented and compared with the most promising methods so far suggested.

Experiments to locate ridges and channels to create a new type of digital elevation model
TL;DR: 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.

Experiments to locate ridges and channels to create a new type of digital elevation model
TL;DR: 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.
