Essay Questions

Discuss the role of physics and mathematics in establishing the truth value and reliability of remote sensing data and derived products. Use examples to illustrate your points.
Compare and contrast the operational principles of different types of remote sensing sensors (e.g., optical imaging, thermal infrared, microwave). What are the advantages and disadvantages of each for specific applications?
Explain the concepts of potential and kinetic energy in a mechanical system (like a swing) and an electromagnetic system. How do these concepts relate to the operation of remote sensing devices and the evaluation of statements about E.M. radiation?
Analyse the process of converting electromagnetic energy into a usable digital signal in electro-optical imaging sensors, from the arrival of photons to the numerical output. How does quantum efficiency and the concept of "buckets" or "wells" fit into this process?
Describe how knowledge is generated in remote sensing based on hypotheses and measured evidence, particularly from photon sensors. How are concepts like probability, statistical relationships, and confusion matrices used to evaluate the truth value of classifications and predictions?
