  • 3. FCE 552: Engineering Survey IV Dept. of Civil Engineering Concept of Remote Sensing (1) Definition Remote sensing is the art, science and technology of acquiring information about the Earths surface without actually being in contact with it. This is done by sensing and recording reflected or emitted energy and processing, analyzing, and applying that information.B. Sc.(Civil Engineering) University of Nairobi

  • 7. FCE 552: Engineering Survey IV Dept. of Civil Engineering Remote Sensing Process (2) The process of remote sensing involves the interaction between the incident radiation and the targets in question. It can be summarized as shown in the figure as:- Energy source or illumination (A)- This is a fundamental requirement in RS and the purpose is to provide electromagnetic energy to the target of interest. Radiation and the Atmosphere (B)- As the energy travels through the atmosphere from the source and the target some interactions will take place. Interaction with the Target (C) – Interactions will take place between the target and the radiation and this will depend on the properties of both the target and the radiation. Recording of Energy by the sensor (D) – Reflected and emitted energy from the target is recorded by a sensor.B. Sc.(Civil Engineering) University of Nairobi
  • 8. FCE 552: Engineering Survey IV Dept. of Civil Engineering Remote Sensing Process (3) Transmission, Reception and Processing (E)-the energy recorded by the sensor has to be transmitted, often in electronic form, to a receiving and processing station where the data are processed into an image (hardcopy and/or digital). Interpretation and Analysis (F) - the processed image is interpreted, visually and/or digitally or electronically, to extract information about the target which was illuminated. Application (G) - the final element of the remote sensing process is achieved when we apply the information we have been able to extract from the imagery about the target in order to better understand it, reveal some new information, or assist in solving a particular problemB.
