Abstract
ABSTRACT This paper reports findings of a laboratory study that attempts to establish the limits of legibility for fundamental cartographic symbology on modern smartphone screens of varying pixel density. In a controlled setting, participants were asked to discriminate different types of cartographic symbology, while stimulus size was gradually reduced. From the collected results, the limits of discriminability for each symbol type and screen resolution are derived. The paper gives a detailed report and statistical analysis of the results of the experiment and proposes updated guidelines for minimum cartographic symbol sizes for settings in which a high-density display device can be reliably provided.
期刊介绍：
The Cartographic Journal (first published in 1964) is an established peer reviewed journal of record and comment containing authoritative articles and international papers on all aspects of cartography, the science and technology of presenting, communicating and analysing spatial relationships by means of maps and other geographical representations of the Earth"s surface. This includes coverage of related technologies where appropriate, for example, remote sensing, geographical information systems (GIS), the internet and global positioning systems. The Journal also publishes articles on social, political and historical aspects of cartography.
