What is GPS?
  • GPS is funded by and controlled by the US
    Department of Defense (DOD), and is operated by
    the US military
  • Satellite signals enable the GPS receiver to
    compute position, velocity, and time.
  • Four GPS satellite signals are used to compute
    positions in three dimensions and the time offset
    in the receiver clock.

7
How does GPS work?
  • A GPS device receives signals from satellites
    orbiting the earth to triangulate your location,
    which will be given as a global address.
  • A GPS device can lead you to a previously marked
    location, much like a compass.

SD Content Standards
  • SCIENCE (Comprehension) 6.E.1.3. Students are
    able to explain processes involved in the
    formation of the Earths structure.
  • plate tectonics, volcanoes
  • Interpret topographic and digital imagery or
    remotely sensed data
  • Use geospatial technologies to investigate
    natural phenomena. Examples GPS, GIS, remote
    sensing

9
SD Content Standards cont.
  • GEOGRAPHY (Application) 7.G.1.1. Students are
    able to select appropriate resources, data
    services, and geographic tools to interpret
    information.
  • Examples atlases, globes, almanacs, thematic
    maps, satellite images, topographic maps, GPS, GIS

10
SD Content Standards cont.
  • SCIENCE (Analysis) 8.E.1.5. Students are able to
    explain the impact of weathering and erosion on
    the Earth.
  • Soil formation, deposition (deltas), land
    transformations (Grand Canyon), glaciation
  • Use geospatial technologies to investigate
    natural phenomena. Examples GPS, GIS, remote
    sensing

What is Geocaching?
  • One of the fastest growing new sports.
  • Has participants in many countries outside of the
    US and Canada.
  • Is a modern day active treasure hunting activity
    that allows you to use GPS and therefore a
    global address to locate a cache.

22
Are there rules for Geocaching?
  • Yes, there are
  • 1. Take something from the cache
  • 2. Leave something in the cache
  • 3. Write about it in the logbook
  • 4. Do not move the cache

  • Geography
  • Some of these graduates work for the city of
    Sioux Falls in the GIS department
