  9. 16:15 General discussion “How can we use remote sensing and drones for global environment studies?”
  10. In the general discussion, an active debate was made on the applications of unmanned aerial vehicles (UAVs, or drones) and remote sensing technologies to the field-based global environmental studies:


    • Why we need use drones? We could do research without drones.
    • The cost of photogrammetry has been decreased by increasing use of drones and improved camera sensors. Now, why don’t we use drones?
    • Drones are in high quality and stable enough to use in the scientific observations. It enabled “free” observations from a bird’s view at the best altitude and resolution we want.
    • It is important that an increasing number of people can use drones on site.
    • I would like to use drones in my farm to monitor plants in real time.
    • Ethical and security issues must be considered carefully as an increasing number of crashing and terrifying accidents happen.

    Remote sensing

    • Google Earth and Quickbird impacted on the researcher’s community around 2005. As well as drones, the remote sensing technologies has been so easy that an increasing number of people can use them on site.
    • It is crucially important for fieldworkers to create a map of villages at study.
    • Only fieldwork can obtain the information related to humans.
    • A kind of literacy is required for interpreting a map.
    • The methods of visual data mining can be used as a communication tool.
    • It is important to share data.
