Objectives

Students will

  • know how to read their current location on a specific model of GPS
  • choose how long to wait for their current GPS location to settle
  • build a visual/spacial sense of how the UTM grid overlays real land
  • choose appropriate direction to walk to achieve intended changes to their current UTM

Advanced students will

  • know how to enter waypoints into their GPS
  • know how to get distance and bearing from their GPS
  • for GPS's without magnetic sensors, get a sense of how far they need to travel for the GPS to know their current heading

Lesson plan

  • Review how to set up GPS
    • Map Datum: NAD27 vs WGS84
    • Grid system: UTM (Canada)
  • Review how to read UTM (Zone, Easting, Northing)
  • Review how to determine accuracy (e.g. 11m)
    • waiting makes more accurate
  • Distribute maps
  • Have students break up into small groups
  • Assign each group a radio and call sign
  • Do a radio test
  • Establish a return to class time
  • Using the answer sheet, the instructor chooses a nearby Target Letter for row ii. All the students fill it in.
  • Each group randomly chooses letters for rows iii to vi. They write them in and the instructor records them on his sheet.
  • go outside the classroom and record the Zone, Easting, Northing and Accuracy
  • Review how to compare Eastings and Northings to compare relative distance and direction
  • as a class, walk to the UTM for the Target Letter of row ii.
  • locate and go to the nearest feature.
  • record the Feature Number, Zone, Easting, Northing and Accuracy for the feature.
  • Compare accuracy of exercise sheet with current accuracy. How do the 2 errors combine?
  • break up into assigned groups and proceed to the remaining 5 Target Letters they have chosen, find the nearest feature and record the Zone, Easting, Northing and Accuracy for the feature.
  • Some groups will complete early, have them do additional targets
