GPS and Geocaching
On May 3, 2000, computer consultant and GPS enthusiast, Dave Ulmer, wanted to test GPS accuracy. His idea was simple: Hide a container out in the woods and note the coordinates with a GPS unit and then post it to a GPS users’ group on the Internet to see if others could find it.
People were challenged to find the “treasure” – a black bucket with a logbook and pencil plus various prize items including videos, books, software, and a slingshot – with only the use of their GPS receiver.
Take some, leave some.
The rules were simple if you found it: Take some stuff, leave some stuff.
Within the first month, Mike Teague, the first person to find Ulmer’s treasure, began gathering the online posts of coordinates around the world and documenting them on his personal home page. The “GPS Stash Hunt” mailing list was created to discuss the emerging activity.
Soon after, this activity became known as Geocaching.
Today, Geocaching is an outdoor adventure activity where approximately three million players worldwide use a free mobile app or a GPS device to find cleverly hidden containers. More than 2.8 million geocaches are waiting to be found in over 180 countries.
GoEngineer’s 3d printing service bureau recently produced a color 3D printed logo for the Geocaching headquarters in Seattle, Washington. The job leveraged both PolyJet and FDM technologies.
