  1. Mapping Kentucky History

  2. The MKH Challenge • Obtain geographical coordinates to the Kentucky Roadside Markers • Use cutting-edge technologies such as Global Positioning Systems and Geographical Information System • Learn about Kentucky’s rich historical heritage

  3. Kentucky Historical Markers Database • Maintained by Kentucky Historical Society and Kentucky Department of Transportation Click on a the map to jump to the interactive map for Kentucky.

  4. Marker Search

  5. Historical Markers Front Back

  6. Global Positioning System - a system of satellites that transmits signals used by special receivers on the ground for precise determination of location, sometimes within meters. Data can include elevation, location, and speed. What Is GPS?

  7. Ranging, why are 3 needed? GPS Satellite

  8. 4 needed for 3-D fix

  9. Why is the system not perfect? • Error sources • Atmospheric • Multipath scatter • Positional error • Cheap GPS Units • Limited satellite channels • Poor internal processors

  10. Obstructions

  11. Bad Luck with Satellites

  12. One solution to the Error – Differential GPS • Use two receivers to eliminate much of the signal error • Increases accuracy to a few centimeters with good units

  13. Consumer GPS Hardware (Cheap) • Consumer-grade • Garmin III plus • >3 meter accuracy • eTrex • Garmin V • <3 meter accuracy 95% of the time • WAAS • GPSMAP 60Cx

  14. Survey-Grade GPS (Expensive) • Survey Grade • Thales Promark2 • Navigation • WAAS <3 m • Post-processing • <1 cm • Kinematic • ~1 cm • Trimble GNSS

  15. GPS Uses • Navigation: • Air & sea navigation • Emergency Services Locating • Airplane landing systems • Car-based direction services. • Mapping • People & places • Animal/plant locations • Historical Markers!

  16. GPS Unit

  17. Turn on & lock onto signals • Push Power Button & Wait

  18. For training inside – turn on simulation mode Press Menu Press Enter To get past splash screen

  19. Satellite Accuracy Satellites’ position in the Satellite constellation Satellite Signal Strength Degree Minute Second Coordinate system

  20. To change coordinate systems – Press Menu Twice Decimal Degrees Coordinate system

  21. Press quit twice To return to main screen

  22. Some GPS tips: • Know how to read the accuracy of the GPS and obtain the most accurate readings. • Thick trees and buildings block GPS receivers from receiving signals from satellites. • Be patient. GPS units require 5-10 minutes to obtain a location after being turned on.

  23. The MKH Team Packet • GARMIN GPS 72 • Instruction Manuals • Morehead State University Pencil • File Folder • Obtaining GPS Coordinate Flowchart • Historical Marker Data Entry Form • Brochures • Free pass to Kentucky History Center
