2. Antiquity Herodotus (circa 450 BC) –Inspired by Pythagoras (530 BC) and his geometry. –Father of geography. –Basic physical and human geography. –Exploration and travel instead of geometry. –Coined the terms Europe, Asia and Africa (Libya).

3. Herodotus (450 B.C.) (recreation)

4. Antiquity Aristotle (circa 350 BC) –Considered physical elements such as the temperature and winds as factors of the human habitat. –Division of the world in 3 climatic zones. –Relationships between the environment (temperature) and human habitat. –One of the first physical geographer. Equator Torrid Ekumene Frigid

5. Antiquity Eratosthenes (circa 250 BC) –Formally assumed the earth was round. –Calculated the circumference of the earth. –40,572 km versus the exact figure of 40,091 km. –Developed the concepts of parallel and meridian. –Consequently introduced the concept of geographical location. –Created modern cartography (cartographic plane).

6. Eratosthenes (194 B.C.) (reconstruction)

7. Antiquity Ptolemy (circa 150 AD) –Refined the coordinate system. –Inventory of population and resources. –Describing the world. –8,000 entries. –Relationships between the physical and human elements. –Created map projections.

9. Middle Ages Period of decline –The cartographic and regional approach was lost in Europe. –Representation of the world was “Christianized”. –Orthodoxy replaced objective observation and analysis. –“T and O” Maps. –Greek and Roman knowledge kept by the Byzantine Empire and by the Arabs.

14. Age of Discovery Exploration and innovation –The 15 th and 16 th centuries were characterized by numerous maritime explorations. –A commercial expansion of European nations. –Several technical innovations. The compass, more precise maps. Larger ships (they passed from 200 to 600 tons during the sixteenth century), better ship structures and the rudder. Insure a safe, fast and therefore profitable maritime navigation. –Creation of the first accurate world maps.

16. Mappa Geographia Universalis (H Sherer 1703)

17. Modern Era A complete world map –Early 20 th century. –Complete and accurate view of the world. –Coordinate systems. –National inventories of resources. Information technologies –Use of remote sensing (aerial photographs and remote sensing). –G.I.S. & Digital maps.

18. "The Living Earth" Satellite Composite, 1995

19. Problem of Distortion All maps, by their very nature contain some type of distortion. –Converting a 3-dimensional spherical surface to a 2-dimensional “flat” surface.

20. Essentials of a good map Title – view knows what to expect Grid – allows for easy, accurate locating Direction arrow or compass rose – to orient the map to reality Scale – to allow one to relate distances on the map to the actual distances on the earth. Key or Legend – so the viewer can understand what the symbols and colors represent.
