PDF-(READ)-Flattening the Earth: Two Thousand Years of Map Projections

As long as there have been maps cartographers have grappled with the impossibility of portraying the earth in two dimensions To solve this problem mapmakers have created hundreds of map projections mathematical methods for drawing the round earth on a flat surface Yet of the hundreds of existing projections and the infinite number that are theoretically possible none is perfectly accurate Flattening the Earth is the first detailed history of map projections since 1863 John P Snyder discusses and illustrates the hundreds of known projections created from 500 BC to the present emphasizing developments since the Renaissance and closing with a look at the variety of projections made possible by computers The book contains 170 illustrations including outline maps from original sources and modern computerized reconstructions Though the text is not mathematically based a few equations are included to permit the more technical reader to plot some projections Tables summarize the features of nearly two hundred different projections and list those used in nineteenthand twentiethcentury atlases This book is unique and significant a thorough wellorganized and insightful history of map projections Snyder is the worlds foremost authority on the subject and a significant innovator in his own rightMark Monmonier author of How to Lie with Maps and Mapping It Out Expository Cartography for the Humanities and Social Sciences. 23 to 24 26 to 30 25 to 30 23 to 25 20 to 23 23 to 25 21 to 32 21 to 30 20 to 27 18 to 27 September projection 20 to 22 26 to 30 26 to 29 23 to 25 20 to 23 18 to 23 21 to 32 21 to 30 20 to 26 18 to 26 Unemployment rate 58 52 to 53 50 to 52 49 to 5 Representing the Earth: Globes.
