  • 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.
