ABSTRACT
While bouncing and jouncing around in the skies, these vehicles collect all sorts of information about a wide range of topics using an equally wide range of sensors. In the technique of remote sensing, especially the subset of UAS remote sensing, the external EM source is almost always the sun. Imaging sensors are the predominant sensor type in the remote sensing world, especially the UAS subset, but the spot sensors can be very useful tools. The phrase in situ comes from the Latin for “in place.” Merriam Webster’s Dictionary defines it as “in the natural original position or place”. Remote sensing is the process of measuring an object or phenomenon from a distance. Airborne remote sensing as a discipline has a wide for large range of sensor options from large multiarrays to single sensor pickup systems. The emitted or reflected particles waves most often associated with airborne remote sensing are sunlight what is called on the EM visible light spectrum.
