Un Resumen sobre Aspectos Fundamentales de la Teledetección y sus Aplicaciones[A Summary on Fundamentals of Remote-Sensing and Applications]

The possibility of taking photographs of the Earth from the sky first, and from space later, has allowed researchers much more than obtaining superb views. Adequately processed and interpreted data obtained from these images through multi-spectral sensors have provided valuable information to diverse branch of the science and public and private institutions. Historically related with the Defense area, information gathered by aerial and spacial photographs have been also well received in the civil sector. The capacity of mounting sensors in satellites to see things invisible for the open human eye brings the possibility to enrich research fields in the same way it improves decision maker due to the higher quality of information. This report has the initial goal of introducing basic topics in the field of remote-sensing, their fundamentals, and the applicability into diverse research fields.
