Questions
“I have never been lost, but I
will admit to being confused for
several weeks.” – Daniel Boone
Locating people/objects in

Urban settings (e.g. EMS, law enforcement)

Water (e.g. lost boats/ person USCG)

Land (e.g. lost aircraft (Civil Air Patrol, DND))

Confined space (e.g. collapsed buildings, mines)

Wilderness – focus of my study
Search
Search –looking for lost person.
Rescue – extricating a person.
Recovery – location and
transport of a deceased.
Primary

Activities

Recovery

National Park Service – paid professionals

VOLUNTEER based – Everywhere else
 In most Western States SAR is responsibility of the
County Sheriff
 Many SAR teams are members of the Mountain Rescue
Association and are funded by donations and
fundraising, not tax dollars

SEARCH – RESCUE - RECOVERY
Variety of sources, formats
Paper:
USGS 7.5" topo maps, 1:24,000 scale, various publication dates
Smaller-scale topo maps, 1:50,000 and 1:100,000, various publication dates
Park/NFS trail maps, scale varies by source, various publication dates
Digital:
Electronic topo maps (e.g. US National Map, Delorme Topo North
America),variable scale and publication dates
Aerial/Satellite Imagery, variable scale and publication dates
Digital Elevation Models, National Elevation Dataset at 30, 10 and 3 meters
GPS units with topo maps (e.g. Garmin MapSource)
Volunteered Geographic Information (VGI). (e.g. OpenStreetMaps, 14ers.com)

Two step process
◦ Hasty Search and containment
- Landscape (e.g. vegetation, terrain)
- Activity (e.g. hiking, running)
- Local knowledge of area (SAR Team)
A
unsuccessful
◦ Detailed Search
- Search Theory (originally developed during WWII)
- Lost Person Behaviour (Koester, 2008)
- Survival rates over time (Koester, 2008)

ISRID (International search and rescue incidents database)
- SAR mission data from around the world (e.g. Australia, USA, UK)
- information on subject type (e.g. age, mental state), search time (i.e.
time it took to find the person), distance traveled, weather conditions
etc.
Used to determine survival rate in different settings

SAR teams mainly volunteer
Lack of GIS expertise within SAR teams to use
GIS and maintain databases
Lack of Funding – training, cost software
Traditionally: a telephone call and a topo map
Now: e911 Phase II, social media, smartphone apps,
mapping GPS units, GIS, etc.
A wealth of geospatial data becoming available but
understanding of how to access and use this data is
in early stages of development

Challenges facing SAR teams is understanding
-
what information is available and how to access
how reliable is the data/information
how the data may be utilized, managed and
integrated during time-sensitive missions.
Purpose: To evaluate what data and technology
may be effectively used in wilderness SAR
missions

Data Gathering
Assessment of Data and Technology
Study Area: Colorado
Mission Data Gathering and Analysis
Current mission data is logged in paper format
- Data for 2-5 years of mission will be digitalized
- Data will be used for part II: Assessment of Data
and Technology
-
-
Interviews and short survey
Data Needs:
Critically assess data needs within current SAR
group Alpine Rescue Team and two external SAR
groups
Technology Assessment:
Critically assess a variety of Geospatial tools
- Identity a wide variety of Geospatial
technologies that will include: full GIS, online mapping tools, smartphone apps
- Develop assessment criteria
Test technology (1-3 apps (1 Full GIS, 1 online
mapping, 1 Smartphone App)) during real SAR
mission

Ease of use
Ability to integrate data
Analytical capabilities
Accuracy
For smartphones – coverage (is coverage reliable)
For smartphone apps – accuracy of tracks,
coordinates
How useful was the application during a mission?
(e.g. quick to get information)
