Description: Contrasts early cartographers' solutions to mapmaking problems with modern solutions, illustrating how changing technology and knowledge of the world has altered mapping techniques. Examines different map projections, using animated models to indicate distortion. Examines latitude and longitude, showing how parallels and meridians can be used to locate any point on earth, regardless of the kind of map projection used. Moves from definition of map terminology to discussion of thematic maps used to represent special aspects of geography, such as rainfall and population density. Concludes with a survey of the tools used by the modern cartographer: aerial cameras, satellites, and computers.
