{ "item_title" : "Navigation", "item_author" : [" Alan Page "], "item_description" : "We are used to seeing the world as a globe. But distances along curved surfaces are not easy to visualise, and navigation between two places on the globe is not just a case of drawing a straight line. So how does it work? This book provides a unique way to see the world through 12 Tile Maps, maps that take sections of the world and make them flat but carefully connected. Using tools provided readers can answer the quizzes about the shortest routes between cities and plot the Great Circle Routes between them without any calculation for their airline and explore the geography of the world as they do it. Minimal craftwork is required to get excellent results.", "item_img_path" : "https://covers1.booksamillion.com/covers/bam/1/91/356/515/1913565157_b.jpg", "price_data" : { "retail_price" : "11.99", "online_price" : "11.99", "our_price" : "11.99", "club_price" : "11.99", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
