4 • Understanding Map Projections SPHEROIDS AND SPHERES The shape and size of a geographic coordinate system’s surface is defined by a sphere or spheroid. Although the earth is best represented by a spheroid, the earth is sometimes treated as a sphere to make mathematical calculations easier. The 地图投影是利用一定数学法则把地球表面的经、纬线转换到平面上的理论和方法。由于地球是一个赤道略宽两极略扁的不规则的梨形球体，故其表面是一个不可展平的曲面，所以运用任何数学方法进行这种转换都会产生误差和变形，为按照不同的需求缩小误差，就产生了各种投影方式。 Find local businesses, view maps and get driving directions in Google Analytical derivation of some map projections including examples of pseudocylindrical and polyconic projections is also covered. Work undertaken in the USA and USSR on the creation of suitable map projections obtained through numerical analysis has been included. The book concludes with a chapter on the abuse and misrepresentation of map
Map projection transformation is an area of research in mathematical cartography newly developed over the last 25 years. It is widely used in surveying and computer-assisted cartography, data processing for information systems, and the transformation of data from space, remote sensing, and › Books › Engineering & Transportation › Engineering. The term map projection can be thought of literally as a projection. If we were to place a light bulb inside a translucent globe and project the image onto a wall—we'd have a map projection. However, instead of projecting a light, cartographers use mathematical formulas to create projections booklet provides a conceptual introduction to map projections, coordinate systems, and geodetic da-tums. We will begin with the latter concept. The shape of the Earth and the geodetic datum concept are covered on pages Page discuss map scale and the basics of coordinate systems. Map projections are introduced on pages , and pages This book essentially displays a whole lot of different map projections, those formulations by which the curved earth gets represented on flat paper. It usually does this with an outline of the United States, which gives us a chance to see that some projections really work only on much smaller areas because using them on something as big as the › Books › Computers & Technology › Computer Science.
