Remote sensing concerns the acquisition of data from radiation sensors installed in space platforms and their later treatment to obtain information about our environment. It is a discipline that is based in measurable magnitudes and verifiable hypotheses that requires a good capacity for analysis and synthesis and that offers to society direct results that improve our knowledge on the physical world. Within remote sensing we can encompass meteorological products, applications aimed to improve agricultural yields, mapping of the terrain, drought control and natural disasters, search for new mining sites, forest management, territory planning, and so on that has not even started as this is a young discipline. The interest for society of scientific studies that are carried out from remote sensing data on the most diverse sides of our environment is easily justifiable given the great amount of operative applications that provide the scientific results that are obtained with it. Remote sensing supplies with thematic maps of our planet, characteristics and variables of interest related with water, soil, crops, and natural vegetation providing periodic and updated information, making easier the continuous tracing and in the long term and helping in decision making to managers in such fields. It provides a form of study in access areas and/or with minimum field support. Remote sensing is also applied to studies on outer space, contributing to a better understanding of the universe that surrounds us.
