Unmanned Aerial Vehicles (UAVs)
We are probably all familiar with drones, or UAVs, as they are virtually everywhere these days. UAVs are remote controlled airplanes and helicopters that are capable of providing surveillance and attack capabilities for military and civilian uses (no attack capabilities in the civilian case, unless you mount a potato gun). Their development grew out of the need for airborne reconnaissance on missions that are either too dangerous or too tedious for piloted aircraft. Today, UAVs have evolved to the point that some platforms are small enough to be easily deployed by a small support team and require only a hand launch or a very short runway. They are often referred to more generically as Unmanned Aerial Systems (UAS), as the vehicles themselves are just one piece of the overall puzzle in most geospatial workflows You may also be interested to look at another one of the GIS courses we offer, GEOG 892: Geospatial Applications of Unmanned Aerial Systems (UAS). It is focused explicitly on how UAVs and GIS working together.
UAVs for Emergency Management
In the emergency management context, UAVs are already used in a variety of ways and new applications continue to emerge.
UAVs are capable of surveying areas very quickly to provide imagery to - or other types of - remotely-sensed data. Satellite data is always valuable and desirable, but satellites cannot always be overhead at the right times on demand. UAVs can be deployed very quickly and can be easily directed toward different areas as the situational picture develops. It is worth noting that UAV footage combined with new approaches to image processing means emergency responders can have high-quality imagery and maps in a matter of hours rather than days.
Click on the image below to see a great example of how UAV footage was used to create a compelling story and reference document about the 2018 Camp Fire in California.

The following 2:28 minute video provides a good illustration of the links between drone mission planning/field operations, image processing, and delivery of products for use in response and recovery activities. Note the time frames involved in this, and how much shorter they are than other traditional aerial or remote sensing efforts. However, the time required to process imagery from those platforms is rapidly shortening as well.
We are all pretty familiar with the use of drones for imagery, but here are a few additional emerging uses for drones in emergency stations. The next video is a bit of a ‘vision’ for drone use and this is followed by a few specific examples of how drones are being used in emergency response.
The following 3:30 minute video: Disaster Response Support with Drones, provides a nice overview.
Payload Drones
It’s not just about Amazon delivering goods to your door… Payload drones are increasingly being used in crises as illustrated in the following videos from WeRobotics and Zipline.

If you have some time it is worth checking out WeRobotics on their website or YouTube. Patrick Meier, the author of Digital Humanitarians, is also a co-founder of WeRobotics.
Now watch the 4:05 minute video about airdrops of medical supplies to African Villages.
Cooperating Drones
Drones are also able to work together to complete tasks. You may have seen the insane “swarm” drone light display at the opening ceremony of the Winter Olympics in Pyeong Chang in 2018. Other applications are being developed such as the three drones working together to build a rope bridge that can support humans in the following (3:26 minute video).

AI and Drones
Finally, I’d like you to consider how drones are being incorporated with other emerging technology such as artificial intelligence. In the video example below (from Australia!) drones are able to identify swimmers, swimmers in need, sharks, stingrays, and many other things. (2:05 minutes)
