Classical cartography has been joined by a more modern approach to geographical analysis, computer-based geographic information systems (GIS).
In their study, geographers use four interrelated approaches: Cartography studies the representation of the Earth's surface with abstract symbols (map making).
Cartographers must learn cognitive psychology and ergonomics to understand which symbols convey information about the Earth most effectively, and behavioural psychology to induce the readers of their maps to act on the information.
They must learn geodesy and fairly advanced mathematics to understand how the shape of the Earth affects the distortion of map symbols projected onto a flat surface for viewing.
Geography is an all-encompassing discipline that seeks an understanding of the Earth and its human and natural complexities—not merely where objects are, but how they have changed and come to be.
Geography is often defined in terms of the two branches of human geography and physical geography.
Names of places..not geography..by heart a whole gazetteer full of them would not, in itself, constitute anyone a geographer.
Geography has higher aims than this: it seeks to classify phenomena (alike of the natural and of the political world, in so far as it treats of the latter), to compare, to generalize, to ascend from effects to causes, and, in doing so, to trace out the laws of nature and to mark their influences upon man.
Examples of areas of research in the environmental geography include: emergency management, environmental management, sustainability, and political ecology.This is 'a description of the world'—that is Geography.In a word Geography is a Science—a thing not of mere names but of argument and reason, of cause and effect.The latter examines the natural environment, and how organisms, climate, soil, water, and landforms produce and interact.Physical geography (or physiography) focuses on geography as an Earth science.
