Line generalisation by repeated elimination of points
TL;DR: A new approach to line generalisation which uses the concept of 'effective area' for progressive simplification of a line by point elimination and offers scope for modelling cartographic lines as consisting of features within features so that their geometric manipulation may be modified by application- and/or user-defined rules and weights.

The Douglas-Peucker algorithm for line simplification: re-evaluation through visualization
Mahes Visvalingam,J. D. Whyatt +1 more
TL;DR: The value of visualization within one problem in cartography, namely the generalisation of lines, is demonstrated and tools for the generation and manipulation of realistic images are of limited value within this application.
Journal ArticleDOI
Cartographic algorithms : problems of implementation and evaluation and the impact of digitising errors
TL;DR: An in‐depth study of a line simplification algorithm shows that computerisation introduces its own sources of variability, and suggests that it would be difficult to adapt the Douglas‐Peucker algorithm to cope with digitising error without altering the method.
