GIS is a system for capturing, storing, analyzing and managing data and associated attributes which are spatially referenced to Earth, in other terms it is an information system capable of integrating, storing, analyzing, editing, sharing, and displaying information which is geographically referenced (establishing a relation between raster or vector images to map projections or coordinate systems). GIS is a tool that allows users to create interactive queries (user created searches), analyze the spatial information, edit data, maps, and present the results of all these operations.
Remote Sensing is the acquisition of information about an object or phenomenon without making physical contact with the object and thus in contrast to on-site observation. Remote Sensing is used in numerous fields, including geography, land surveying and most Earth Science disciplines (for example, hydrology, ecology , oceanography, glaciology, geology); it also has military, intelligence, commercial, economic, planning, and humanitarian applications.
