The SAGE Handbook of Geographical Knowledge is a critical inquiry into how Geography as a field of knowledge has been produced, re-produced, and re-imagined.

Remote sensing is the art, science and technology of obtaining reliable information about the Earth (or other physical objects) and its environment through the process of acquiring, recording, analyzing and interpreting imagery and other representations of energy patterns derived from non-directly-contact sensor systems by means of electromagnetic radiation.1 With electromagnetic radiation traveling at the speed of light, the sensors collect information of the remote objects through an instantaneous process. Reading is such a process, in which our eyes (i.e. the sensors) sense the reading materials (the objects) from about one foot away through the light reflected from the materials (Lillesand et al. 2007). Our brain (the mental computer) analyzes the sensed image and recognizes a collection of letters, ...
