TL;DR: In this article, the authors present an extended review of the publication Cartometric Measurements, by H. Kishimoto, concerned with three basic problems: (1) the sorts of errors which may result from using different instruments and methods of measurement and how these may be corrected.
Abstract: This is a summary of the problems which are involved in the apparently trivial task of measuring the length of a sinuous line on a map. It represents an extended review of the publication Cartometric Measurements, by H. Kishimoto. It is concerned with three basic problems: (1) the sorts of errors which may result from using different instruments and methods of measurement and how these may be corrected: (2) the sorts of errors which may occur in the map and how these may be corrected: 3) the fundamental problem of what is 'length'. Extensive use is made of East European literature on these subjects.

TL;DR: In this paper, visual perception is reviewed in relation to the search for principles in map design and various cues of "depth" are examined as aids in the specification of the qualities and dimensions of map symbols.
Abstract: Visual perception is reviewed in relation to the search for principles in map design. Various cues of 'depth' are examined as aids in the specification of the qualities and dimensions of map symbols. Maps are analysed on the basis of 'receding planes', each plane containing a specific selection of graphic information. A design procedure is outlined in this content, and finally an example of a thematic map, the Residential Land Use of Glasgow-1965, is presented in detail.

TL;DR: The early One Inch maps of the Ordnance Survey of Great Britain, especially those published in the period up to c. 1820 were far less accurate than subsequent maps in the Old Series as mentioned in this paper.
Abstract: The early One Inch maps of the Ordnance Survey of Great Britain, especially those published in the period up to c. 1820 were far less accurate than subsequent maps in the Old Series. The paper relates this characteristic to the changing organization and methods of topographical survey, and discusses hitherto unexamined evidence for the widespread revision of inferior maps.

TL;DR: The methods used in the Land Use Survey of Malawi are described as an example of how statistical sampling applied to air photo coverage can give adequate information economically about the distribution of types of cultivated, uncultivated and uncultivable land as discussed by the authors.

TL;DR: In this paper, the basic problems of presenting statistics on maps are treated mainly from the statistical point of view, and the relevance of such fundamental values as measures of centrality is explained and the use of the distribution cross for geographical statistics is presented in detail.

TL;DR: The problems of devising university courses in topographic science subjects, culminating in the institution of a full B.Sc. degree, are examined in relation to parallel developments elsewhere as discussed by the authors, in the expectation that specific examples will provide discussion points for those concerned with the development of education in cartography.
Abstract: The problems of devising university courses in topographic science subjects, culminating in the institution of a full B.Sc. degree, are examined in relation to parallel developments elsewhere. Details of course content and structure are given, in the expectation that specific examples will provide discussion points for those concerned with the development of education in cartography.

TL;DR: In this paper, the authors examine the factors of changing navigational requirement on the one hand and of cartographic opportunity on the other which have led to the new policy and a number of practical limitations imposed on cartographic expression in marine charts are outlined.
Abstract: In 1967 the Hydrographer of the Navy, guided by a report from his professional advisers and with the support of many chart users with whom the main proposals were discussed, took a number of decisions to modernise the Admiralty Chart. The author heads one of the sections of the Nautical Chart Branch; and this paper, which follows lectures given to the Society last year, examines the factors of changing navigational requirement on the one hand and of cartographic opportunity on the other which have led to the new policy. A number of practical limitations imposed on cartographic expression in marine charts are outlined.

TL;DR: The use of the date stamp, where this has been retained, is shown to be a useful and reliable method in relation to the early Ordnance Survey one inch sheets.
Abstract: The problem of dating maps for purposes of historical and other research is examined in relation to the early Ordnance Survey one inch sheets. The use of the date stamp, where this has been retained, is shown to be a useful and reliable method.

TL;DR: In this article, the general problems of producing a national atlas are discussed and illuminated with specific examples, including the problems of organizing, compiling and generalising, selection of contents, scales, and other basic issues.
Abstract: The general problems of producing a national atlas are discussed and illuminated with specific examples. Organisation, compilation and generalisation, selection of contents, scales, and other basic issues are treated in the first place, and these are followed by an examination of the more subtle cartographic problems of design, colour, and the presentation of statistics. A provisional table of contents is appended.
TL;DR: The emergence of eighteenth-century private mapping, on a scale approximating to one inch to a mile, is placed in a Welsh regional setting, and various abortive 'Proposals' are examined, and the relevance of the study of estate maps, local surveyors and their practices is stressed as an essential complement to knowledge derived from printed maps.
