TRANSCRIPT
Having trouble finding your way?
• 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.
What is GPS?
• 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.
How does GPS work?
SD Content Standards
• SCIENCE (Comprehension) 6.E.1.3. Students are able to explain processes involved in the formation of the Earth’s 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
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
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.
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
GPS Career
• SDSU offers bachelor’s degrees – Geographic Information System (GIS)
– Geography
• Some of these graduates work for the city of Sioux Falls in the GIS department
City of Sioux Falls
