TLDR
An account of a series of experiments in computer generalisation, in which the outline of the Netherlands at 1:25 000 scale has been used to generate aseries of generalisations between 1:600 000 and 1:3 500 000.
Abstract
This is an account of a series of experiments in computer generalisation, in which the outline of the Netherlands at 1:25 000 scale has been used to generate a series of generalisations between 1:600 000 and 1:3 500 000. Eight examples are reproduced, six of which compare the automatic generalisation with one taken from the Atlas of the Netherlands and the other two compare automatic generalisation using all digitised coordinates with that derived from using mean values of successive coordinates.The article was first published in Tijdschrift voor Kadaster en Landmeetkunde, 1969, 6, Leiden, under the title, “Toepassing van de reken-en-tekenautomaat bij structurele generalisatie” and is published here by kind permission of the Editors.

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.

Treatment of the cartographic line

TL;DR: A reconsideration of trends in cartographic research is presented, to explain how the change in generalization from 'elimination' to 'enhancement' has developed.

Algorithms for Geometric Covering and Piercing Problems

Robert Fraser
TL;DR: This thesis involves the study of a range of geometric covering and piercing problems, where the unifying thread is approximation using disks, and outlines approximation algorithms for the general DUDC problem which make use of the algorithms for LSDUDC and WSDUDC.

Generalisation and realism within automated cartographic systems

TL;DR: The principles and practice of generalisation of cartographic elements in an automated system should not be assumed to be the same as those in manual cartography, but certain types are much more easily and usefully achieved than others by computer.
