    • Introduction to GPS Technology Vince DiNoto Co-PI National GeoTech Center [email_address] Funded by National Science Foundation DUE 0801893
    • National Geospatial Technology Center of Excellence Empowering colleges to expand the geospatial workforce. Vince DiNoto Dean of College and Systemic Initiatives [email_address] Funded by National Science Foundation DUE 0801893
    • Spatial Thinking vs Jobs
      • What are the educational requirements?
      • Where are the jobs?
      • What are the tasks?
      • What is spatial literacy?
    • What is the GeoTech Center
      • An NSF funded ATE National Center of Excellence
      • Single point of contact for two year colleges
      • A Geospatial curriculum repository
      • A data warehouse (data, static maps, dynamic maps)
      • A best practice in Geospatial
    • GeoTech Center Players

    • Resources
      • GPS Information http://techcenter.jefferson.kctcs.edu/RS/topics/GPS/Pages/default.aspx
      • Geospatial Information http://techcenter.jefferson.kctcs.edu/GIS/Pages/default.aspx
    • What is a Global Position Device (GPS)
      • It is a device which receives
      • information from satellites
      • The device is a receiver only,
      • some devices have transmitters
      • associated with them, but only
      • to a cell phone type connection.
      • Some devices have a GPS like function from Cell Phone Towers.
      • There are ground based GPS Stations
    • How does a GPS Work
      • 24 GPS Satellites orbit the
      • earth every 12 hours.
      • ~11,000 miles above the earth
      • Each satellite has an atomic
      • clock
      • Each satellite sends out a time signal at speed of light
      • The difference in the time reading can determine the distance to the satellite
    • How does a GPS Work (cont.)
      • If you can determine the
      • distance to the satellite you
      • can determine your position
      • on earth
      • The more satellites better the accuracy
      • Can do three dimensional positioning
      • Ground based stations increase accuracy
      • Clear days better signals and better accuracy
    • Wide Area Augmentation System WAAS
      • Ground based positions
      • Only North America
      • Local Ground based stations
    • Data Collection
      • Waypoints
        • A location recorded either on the GPS or placed into the GPS
        • Naming points use a notebook instead trying to write a name on the GPS
        • Photograph point
        • Adding Geotags to your pictures
    • Types
      • Handheld
        • May or may not have a map screen
      • Car Mounted
        • Map Screen
      • Computer Connected
        • Maps on Computer Display
      • Cell Phones
      • PDA
      • Kindle
        • Cell Phone position
      • Camera Connection
    • Interface
      • Serial – many computers do not have a Serial connection any longer. Cable can be purchased to go into USB port
      • USB – best solution
      • Bluetooth – wireless solution
      • Software
        • Purchase
