Happy Holidays!

This is my report on a research article that covers the future of unmanned system applications




           This article, Drone methodologies: Taking flight in human and physical geography, fully supported the use of unmanned aerial systems (UAS) in the fields of physical and human geography. The three aims of this paper were to “start a discussion” between different geographical fields to foster the spread of UAS methodologies, to discuss how UAS “expand the potential for thinking about  ‘visual’” geographic uses, and to also do the same for “volumetric” methods. The authors also proposed the creation of drone airspace where drones can operate above obstacles but safely stay below air traffic. This airspace was coined the “Neophosphere” which was derived from the Greek word for cloud (nepho) and sphere (which is also a Greek word).  This airspace carries the characteristic of also being the volume of air from which a drone can operate within contact with its human manned control center. For example, a line-of-sight drone would have a small localized Neophosphere compared to the Global Hawk military drone which has a global-reaching Neophosphere (Garrett & Anderson, 2018). In addition to these goals, the article explored and discussed not only the impact that UAS could have on geographic methods, but also the possible political and societal implications of UAS.


            Defining and creating a Neophosphere is something I agreed with the authors about. The FAA in the United States had worked hard in recent years to create regulations to facilitate drones into the national airspace (Federal Aviation Administration, 2019). These regulations however lacked the completeness of the Neophosphere proposed by the authors. Using already defined airspace was an advantage of the Neophosphere proposal. It would include the FAA defined airspace that is closest to the ground and below most general and commercial aviation traffic (Garrett & Anderson, 2018). In aviation language, the Neophosphere would encompass class G airspace where crop-dusters, helicopters, and low-flying aircraft, well-accustomed to the dangers of low-flying bird and drones, operate. I agree with this argument for a defined airspace for drones because the current FAA rules were few and limited in scope. The rules only stated that a drone must be registered, stay below 400 feet, and not fly into airport-controlled airspace (Federal Aviation Administration, 2019).  I also think that a bit of education about FAA airspace would educate drone pilots better about the general aviation aircraft their drones might encounter.

            A point that this article made was that geographers use UAS in small volumes of the Neophosphere when there is much more airspace to use to enhance UAS operations. An example was of recent digital mapping project of the “Christ the Redeemer” statue in Brazil. Researchers started the project using satellite images (like traditional geographers) and found that these images lacked the detail to accurately render the statue. Local, on-sight images of the statue were also used to provide more fidelity but they couldn’t capture details on the top of the statue. UAS fitted with cameras flew around the statue and finally provided the full image overage and fidelity needed to create the desired rendering (Garrett & Anderson, 2018). This example was a very strong argument for the unique capabilities that drones provide provided that operators take full advantage of available airspace.
            The case most brought up was the fact that many people associate drones with an oppressive narrative of being the ever-watching eyes of an oppressive “Big Brother” observer. Whether it was a drone operated by law enforcement to monitor crime or a hobbyist enjoying some sight-seeing, people associate drones with the fear of being constantly monitored. A defense for operators was to create and know the policies and laws that govern drone use. The author recalled the story of using a drone to film a skyscraper under construction while on a trip. A security guard from the building demanded that the author stop filming the building because the building is privately owned. The author calmly explained that he was filming from a public park in uncongested airspace implying that he was legally allowed to film the building. The frustrated security guard snapped back with the claim that air around the building was also privately owned! (Garrett & Anderson, 2018).  

            Lastly, the authors argued that UAS could be used in new, creative, and innovative ways to gather data. Many geographic methods involving UAS were limited to just using aerial imaging operated by a line-of-sight pilot. The article argued that drone technology had advanced to the point that other sensors and other control methods could be used to conduct geographical surveys. One example was to use autonomous drones more to survey wide swaths of land. I agreed that this technology is useful because other industries like the pipeline monitoring industry used and are considering autonomous drones for surveillance (Kochetkova, 2019).
            Overall, I agree with the points this article made about UAS applications in geographical studies. UAS can provide an enormous advantage but they still have several political and societal challenges to overcome.
