TLDR
The fundamental of cartographic generalisation, the reduction of the amount of information which can be shown on a map in relation to reduction in scale, is examined and the introduction of two constants to represent symbolic exaggeration and symbolic form is introduced.
Abstract
The fundamental of cartographic generalisation, the reduction of the amount of information which can be shown on a map in relation to reduction in scale, is examined. The Principle of Selection was first proposed by Topfer in 1961, and is expressed as an equation relating the number of occurrences of a particular feature at source map scale and at derived map scale. The application of this to small-scale maps involves the introduction of two constants to represent symbolic exaggeration and symbolic form. Examples are given and illustrated. The paper is accompanied by explanatory notes by Dr D. H. Maling, who presented the paper on behalf of the authors at the XX International Geographical Congress London 1964, Section IX, Cartography.

Spatialization Methods: A Cartographic Research Agenda for Non-geographic Information Visualization

TL;DR: It is argued that cartographically informed engagement of computationally intensive techniques can help to provide richer and less opaque information visualizations and distinguishes two equally important sets of challenges for cartographic success in spatialization research.

Cartographic generalization in a digital environment: when and how to generalize

TL;DR: This paper will address the question of cartographic generalization in a digital environment by presenting a logical framework of the digital generalization process which includes a consideration of the intrinsic objectives of why the authors generalize; an assessment of the situations which indicate when to generalizing; and an understanding of how to generalize using spatial and attribute transformations.

Systematic Generalization, Historical Fate, and the Species Problem

TL;DR: The species problem is one of the oldest controversies in natural history as mentioned in this paper, and its persistence suggests that it is something more than a problem of fact or definition, which is why it is referred to as the "species problem".

Multiscale visualization using data cubes

TL;DR: A formalism for describing multiscale visualizations of data cubes with both data and visual abstraction and a method for independently zooming along one or more dimensions by traversing a zoom graph with nodes at different levels of detail are presented.

Process mining in flexible environments

TL;DR: In conclusion, proton-proton collisions have been identified as the source of radioactivity in the Large Hadron Collider and their consequences have been described as “catastrophic” and “fundamental” in the design of the machine.
