I. Definitions and Basic Concepts
Remote sensing is the science, technology and art data acquisition and data processing to record the interaction between electromagnetic energy to an object. In other words can be defined as the science, technology and art of obtaining information about an object, area, or phenomenon through the analysis of data obtained with an instrument without direct contact with the object, area, or phenomenon under review.
In general, remote sensing showed activity recording, observation and capture the phenomenon of objects or events from a certain distance. In Is Much far, the sensor does not directly contact with the object being observed. Conductor means that information needs to physically travel from the object to the sensor through the medium.
Tutorial on training is more limited remote sensing technology to obtain information on the Earth's surface (sea and land) by using a sensor on the satellite platform and Spaceborne (spacecraft).
