emote sensing and geographic information systems can be defined as follows: “Remote sensing is any method of obtaining and recording information from a distance. The most common sensor is the camera; cameras are used in aircraft, satellites, and space probes to collect information and transmit it back to Earth (often by radio). The resulting photographs provide a variety of information, including archeological evidence and weather data. The images are also used in map-making. Microwave sensors use radar signals that penetrate cloud. Infrared sensors measure temperature differences over an area. Computers process data from sensors.” ("remote sensing" World Encyclopedia. Philip's, 2005. Oxford Reference Online. Oxford University Press. Charles Darwin University. 12 September 2005 ). “Geographic (Geographical) Information Systems (GIS), GIS are integrated, spatial, data-handling programmes which will collect, store, and retrieve spatial data from the real world. They are powerful tools in decision-making, as they can incorporate co-ordinated data. It should be noted, however, that GIS only contain selected data; solely the properties which investigators have considered relevant, so that many variables will not be fed into the systems.” "Geographic (Geographical) Information Systems" A Dictionary of Geography. Susan Mayhew. (Oxford University Press, 2004. Oxford Reference Online. Oxford University Press. Charles Darwin University. 12 September 2005 ) The relationship between remote sensing and GIS
