Geography deals with the aerial differentiation of the earths surface. It includes study of factors such as physical features, climate, soil, vegetation, population, land use and industries all over world and their regional differentiation.
Due of the latest technological developments like Remote Sensing and Geographical Information System (GIS), careers in geography are becoming more promising and challenging than ever before. Remote Sensing is the science that acquires information about an object, area or anything, without direct contact with the objects. The informations are transferred with the help of electromagnetic radiation (EMR) which is a form of energy that reveals its presence by the observable effects it produces when it strikes the matter. GIS is a computer based information system which is used to digitally represent and analyze the geographic features present on the earth surface and the events that take place on it. In GIS data collection, GPS (Global Positioning System) technology which uses satellites and computers to compute positions anywhere on earth with unequalled accuracy and flexibility has tremendous amount of applications.
