Combining state-of-the-art cartographic technology and information with dynamic and diverse physiographic and cultural content, the Eight Edition is National Geographics most accurate and interesting record of the world yet. The opening section, Ninety Years of Mapping at National Geographic, traces the founding of Geographic cartography to the present advances in technology and the practice of compiling and organizing geographic information. The atlas truly begins with three stunning new, full-spread world maps, that drape Earths surface seamlessly with satellite imagery, then physical and natural features, and finally todays political world of countries and growing cities.World thematic topics are organized into two groups: the Physical and Natural World and Human Activities. The Physical and Natural World section includes captivating core topics such as the evolution of earth, geology and tectonics, climate and weather, oceans, world water, the bioshere, and biodiversity. Human Activities covers 11 world themes: population, migration and refugees, conflict and terrorism, cultures, economy, energy and minerals, communications, food, health and education, the environment, and ending with wildlands. All of these intriguing spreads reflect the most authoritative and recent data available and are reviewed by preeminent scholars and experts. Lined up after the world thematic focus is the continental division. All seven continents open with views from space and are then represented with separate physical and political maps. Larger scale regions of each continent are presented for higher definition and detail. Because of our primary readership, additional coverage is given to the UnitedStates and Canada. An entirely new component to the Eighth Edition is the city section. Maps and text discussing urban explosion will open this compilation of sixty new maps. Pictures, fact boxes, and text will accompany each city map to create colorful and informative portraits of our built environment. Selected cites such as, New York, Mexico City-the most densely populated city in the world, and Paris will receive more detailed scaling. Less familiar and remote areas of the world and beyond-the poles, the ocean floors, and space-are mapped with new data and findings and dramatic effects. The addition of a new spread and map devoted to Mars will provide a timely reference to the expected news coverage of NASAs Mars Exploration Rover Mission-S
