 | | Human geography may in turn be subdivided into a number of fields, such as economic geography, political geography (with its 20th-century offshoot, geopolitics), social geography (including urban geography, another 20th-century ramification), environmental perception and management, geographical cartography, geographic information systems, and military geography. |
 | | Historical geography (which reconstructs geographies of the past and attempts to trace the evolution of physical and cultural features) and urban and regional planning are sometimes considered branches of geography. |
 | | Geography was first systematically studied by the ancient Greeks, who also developed a philosophy of geography; Thales of Miletus, Herodotus, Eratosthenes, Aristotle, Strabo, and Ptolemy made major contributions to geography. |
