Questions and information about using technology to support wilderness search and rescue.
Ron Zeeman is an incident commander-level volunteer with Utah County Search and Rescue. He has been the subject matter expert for all of the NSF-sponsored work on using UAVs to support wilderness search and rescue, including leading most of the field trials. He is also developing technology to support underwater search, unmanned helicopter-based search, and computer vision from manned aircraft.
Craig Snyder is from the Greater Philadelphia Search and Rescue group located outside of Philly. We are a SAR team serving SE Pa, and parts of NJ and DE. We have been around since 1976 and provide trained ground searchers, K-9 teams, and search managers for searches headed up primarily by law enforcement and fire departments. They are currently working on providing aerial capabilities to the team. They work in a mixed wilderness/suburban/urban area. Our needs are slightly different then what the western teams are probably looking for. Many of their searches are also probably of a much different nature. They are looking for aerial support for initial recon of the area, identification of hazards, unmapped structures, terrain type, and high probability targets. They also want to be able to monitor the progress of their tracking teams and K-9 task teams and to monitor the area immediately in front of them. They often deal with people who don't necessarily want to be found and they actively avoid the search teams; note that these are not criminals, but rather people who are mentally impaired or scared for one reason or another..
Walter Arlt is a retiree who works with his son on a variety of technologies for supporting human welfare. Their company has recently been working on developing UAVs for use in various applications including search and rescue. Videos of their work can be found here.
Nelson Trichler is from Santa Barbara County Search & Rescue. Their overall operations naturally rely on their experience, both in what subjects have done in the past and their knowledge in the areas someone is lost. The latter requires getting out and seeing what the terrain is like: Is it flat ground with little vegetation or mountains with think chaparral that limits one's ability to move through therefore they tend to stay on established trails? Visibility is a key factor in their searches. If someone is in the wilderness and cannot see any specific reference points then they might go anywhere. On the west coast many of the coastal mountains overlook the ocean so most persons know that if you go downhill you will eventually run into the coast and other people. The trouble is the vegetation and the ability to get through it if the person is off trail.
Don Ferguson is a well-respected volunteer who has been involved with search and rescue for over 10 years. He has contributed significantly to an understanding that efficient SAR planning involves a lot more than just have a lot of people walking around in the woods. Understanding how individuals interact with their environment plays a key role in SAR planning, and is very familiar with Robert Koester's work.
Steve Campbell is working to bring together a project team using ArcGIS to build on our significant lost person behaviour data. The ESRI team here is talking with staff at Yosemite National Park who are doing some work too and we are hoping to build on their computer models.
Charles Twardy is a researcher at George Mason university with expertise in search theory and analysis of lost person behavior. We are currently working with him to try and obtain funding that will allow him to lead an effort to evaluate the quality of various searcn maps and models. Charles and Bryan Morse have made some funding available that may allow us to get some of Robert Koester's time to consult on this project.
Robert Koester is both an Incident Commander and a researcher interested in Lost Person Behavior, Sweep Width, and general SAR theory. He has done extensive work on using past data to help identify probability of area (POA) models to guide search. Lanny's work might be able to add something to Bob's work by looking at how a particular individual is likely to travel through a specific terrain of interest. Ideally, it would be best to find a way to integrate Lanny's work into Bob's excellent foundation work.
