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
