Issued without a dust jacket. -- A classic text and reference work for students, academics and professionals approaching cartometry from a wide range of backgrounds: geography, cartography, forestry and stereology. The author has transcended these subject boundaries to produce a definitive and coherent guide to the theory and technique of measuring distance and areas on maps. To increase this book's accessibility, a minimum of mathematical knowledge is assumed. The book describes the accuracy of a variety of measurement techniques that may be used in many fields of science, administration and travel. Composed of 23 chapters, it begins with a description of the nature and applications of cartometry. The succeeding chapters deal with methods of measuring distance and area, sources of measurement errors and their analysis, cartometric sampling, the concept of accurate map, and the magnitude of cartometric deformations, followed by discussions of aerial photograph measurement. Contents: 1. Nature of Cartometry (Uses of Cartometry; Measurement for Route-finding; Cartometry in Administration; Cartometry and the Law of the Sea) 2. Nature of the Medium (Map as the Medium; Geometry of the Medium to Be Measured) 3. Methods of Measuring Distance (Measurement of Distance; Measurement by Dividers in Equal/Unequal Steps; Measurement of Distance by Digitiserdistance; Measurement by Comparison With a Piece of Thread & by Chartwheel) 4. Measurement of Area (By Calculation; By Comparison With Standard Figures; Method of Squares; Point-Counting Methods; Indirect Methods by Point-Counting; By Linear Measurement; Transect Sampling as a Method of Area Measurement; By Tracing Parcel Perimeters; Miscellaneous Methods) 5. Variability of Cartometric Measurements (Examples: Lengths of the Coastline of Yorkshire & the World & the USA & USSR; Discussion of Examples) 6. Errors of Measurement and Their Analysis (Nature of an Error; Causes of Errors; A Classification of Errors; Normal Distribution) 7. Statistical Sampling and Cartometry (Properties of a Sample; Size of Sample; Statistics of Small Samples; Significance of the Difference Between Two Means) 8. Spatial Sampling and Cartometry (Sampling Frame & Units & Strategy; Spatial Methods; Stratified Random Sampling; Comparison of Spatial Methods; Size of Spatial Samples) 9. Concept of the Accurate Map (Components of Map Accuracy; Standards; Testing Quantitative Accuracy; Circular Probability; Height Errors; Components of Quantitative Accuracy; Total Root Mean Squares Error of a Map; Qualitative Accuracy; Sampling Strategy in Qualitative Testing) 10. Deformations of the Medium (Representation of the Curved Surface of the Sphere as a Map; Scale of a Globe; Angular Deformation; Special Properties of Map Projections; Choice of the Most Suitable Projection for Cartometric Work; Area Measurement on Topographical Maps & Aeronautical Charts; Deformation of the Map Base) 11. Correction of Deformation by Measurement Control (Correction to Linear Measurements; Determination of Area by the Savich Method; Format and Size of the Unit Quadrangle; Control of Area Measurements by Means of Zones).
