Using GIS inSearch and Rescue

Search: To locate persons in distress

Rescue: To retrieve persons in distress, provide for their initial medical or other needs, deliver them to a place of safety and get your teams out safely.

Search is often the more time-consuming task:

• Where to look?• What resources to use?• How long do you look?

SAR: The Basic Map

A map is not the territory it represents, but if correct, it has a similar structure to the territory, which accounts for its usefulness.

-- Philosopher and Scientist Alfred Korzybski, 1931

• “What hampers me as a searcher is that I don't think like a lost person (well, mostly ...). Maybe one (two?!?) out of 10 times have I looked at a map, waved my divining rod over it and said: "There!" and been anywhere close to right. Each SAR is like learning all something new each time. So the priority tools (and tech devices), for me, would be those which contribute to better organizing and visualizing the SAR and the terrain.”

GIS & MapSAR: Capture spatial information in organized and retrievable structure.

Next: Quickly produce accurate team and briefing maps.Get teams into the field!

MapSAR: Allows automatic customization of team maps. DDP produces those maps quickly.

3D Image (ArcGIS Explorer or ArcGlobe): Effective Visualization of terrain for teams and Incident Command

ArcGIS Explorer can be set to poll data automatically, giving it the potential to be usedas a semi-realtime situation map projected into the Incident Command Post.

SAR dispatch enters clues and team locations in networked geodatabase which become immediately available to Command staff.

When applied to GIS, Korzybski’s “the map is not the territory” is a warning not to make maps or computer analysis a substitute for local knowledge and a team’s skill.

For all of this technology’s potential, the lost and injured are found and rescued by dedicated searchers working in difficult and dangerous conditions far from help themselves.

Effective SAR is founded on the actions of searchers voluntarily leaving a warm and comfortable environment to go out in often horrendous weather and terrain to look for a lost person. SAR will always require people with specific knowledge of an area to be able to properly evaluate and make decisions based on that experience.

GIS, though, is a vital tool to efficiently and effectively envision complex information – turning a flat piece of paper into a better approximation of the territory.
