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.
Journal ArticleDOI
The Signed Chi-square Measure for Mapping
TL;DR: In this article, the effect of sample size can be accommodated by a modified form of the X2 test statistic, which is described in this paper and can be used for mapping and statistical analysis.
Journal ArticleDOI
Implications of Weighting Metrics for Line Generalization with Visvalingam's Algorithm
TL;DR: This paper shows how free software and data were used to scrutinize the implications of one of Matthew Bloch's simple and transparent weighting functions, and demonstrates how weights can undermine the algorithm's capacity to draw caricatures with very few points.
