TL;DR: In this paper, the efficiency of symbols in the legends of two comparable published tourist maps using a symbol comprehension method was analyzed with respect to the ease and accuracy with which the symbols were understood by subjects.
Abstract: This study analyses the efficiency of symbols in the legends of two comparable published tourist maps using a symbol comprehension method. Relative effectiveness is assessed with respect to the ease and accuracy with which the symbols were understood by subjects. The results highlight those point symbols that are inefficient. These were found to be mainly abstract, geometric or pictorial symbols that bear a poor resemblance to the object they are attempting to depict.

TL;DR: The Piezopleth maps as discussed by the authors are a particular case; their construction rests on a physical model used for strength resistance calculations and structures resolution in civil engineering locations and thematic variables are combined in the same process; their interrelations point out the differences in potential and are expressed by distortions of surfaces of the structure and shifting of locations.
Abstract: Numerous types of anamorphoses, or cartographic transformations, have been perfected, leading to a distorted picture as compared to the usual map representations Piezopleth maps are a particular case; their construction rests on a physical model used for strength resistance calculations and structures resolution in civil engineering Locations and thematic variables are combined in the same process; their interrelations point out the differences in potential and are expressed by distortions of surfaces of the structure and shifting of locations This process, which requires the elaboration of a geographical background with a mesh structure, gives unusual but very expressive maps, whether in comparing phenomenons on a given date or the same phenomenon through time

TL;DR: It is argued that all types of graphic information are different solutions to a common problem: the brain's limited capacity to store unprocessed information.
Abstract: This article considers the similarities and differences between maps and other types of graphic information such as graphs and diagrams. It is argued that all types of graphic information are different solutions to a common problem: the brain's limited capacity to store unprocessed information.

Journal ArticleDOI
TL;DR: In this paper, various problems involved with scientific map evaluation are examined with the aid of an example from experimental cartography, and the objective results give us information about the design characteristics of the maps and indicate where improvements could be made.
Abstract: The various problems involved with scientific map evaluation are examined with the aid of an example from experimental cartography. Point symbols from two Australian city street directories are compared experimentally. The objective results give us information about the design characteristics of the maps and indicate where improvements could be made. However limitations in experimental design and subjective elements in the experimental process are exposed and examined in the context of the search for the general theoretical principles of map design.

TL;DR: It seems that cubic splines with geometric continuity rather than mathematical continuity are more appropriate for compressing contour maps for computer processing.
Abstract: A contour map is a convenient representation of three-dimensional data. Although, when displayed, it does not provide an immediate visual three-dimensional image, it is useful in practical applications. It is tedious to manually draw or extract data from a contour map. The ability to store contour maps for computer processing is thus desirable. A contour map is conventionally stored in a computer as a set of polygons. This method unfortunately requires a large amount of storage and is not convenient for subsequent editing of contour maps. More recent techniques use cubic splines with mathematical continuity. Although such techniques require less storage than the conventional method, they do not provide a convenient means for subsequent editing. From recent reports on research in Computer Aided Geometric Design as well as in Computer Aided Design and Computer Aided Manufacturing, it seems that cubic splines with geometric continuity rather than mathematical continuity are more appropriate for comp...

TL;DR: A map overprinted with the known information relevant to one specific archaeological or historical period rather than a general survey was developed by O. G. S. Crawford during his period of tenure as the Ordnance Survey Archaeology Officer, and, after the war, by his successor, C. W. Phillips.
Abstract: A map overprinted with the known information relevant to one specific archaeological or historical period rather than a general survey was a concept developed by O. G. S. Crawford during his period of tenure as the Ordnance Survey Archaeology Officer, and, after the war, by his successor, C. W. Phillips. This paper discusses the making of these maps, and cites the known cartographical, bibliographical and manuscript sources relevant both to the published maps and to those which failed to reach publication.

TL;DR: In this paper, a numerically convenient general solution in establishing mapping equations for conformal projections of areas on the earth-ellipsoid to the plane using so-called harmonic polynomials is presented.
Abstract: The paper presents a numerically convenient general solution in establishing mapping equations for conformal projections of areas on the earth-ellipsoid to the plane using so called harmonic polynomials. The application to a projection of Gauss-Kruger type for the regions of Greece and West Germany yielded a satisfactory solution with polynomials of 6th degree.

TL;DR: The most comprehensive cartographic source of information on industrial location in England and Wales during the 'Industrial Revolution' is the family of large-scale county maps produced between 1700 and about 1840.
Abstract: The nature of the 'Industrial Revolution' between 1700 and c. 1840 is frequently misunderstood, creating a picture of dynamic multi-faceted industrial growth which is far from the truth. Most industry remained rural, dispersed and powered by wind or water. Cartographic sources have largely been ignored in studies of industrial location, yet they have much to offer, illuminating the subject in ways which documentary sources cannot. The most comprehensive cartographic source of information on industrial location in England and Wales during the 'Industrial Revolution' is the family of large-scale county maps produced between 1700 and about 1840. Their worth as a source of industrial information has generally been underrated. However, if they are to be of value to the industrial historian, it is necessary to understand what they show and why, and equally what they fail to show.

TL;DR: The National Atlas of Wales (NAOW) as discussed by the authors was the fourth and final instalment of the NAL, which was published in 1989, and has been widely used since.
Abstract: Spring 1989 saw the publication of the fourth and final instalment of the National Atlas of Wales.This paper traces its origins and the factors influencing its development and outlines aspects of its design, compilation and production.
