== Prerequisites ==
{{prompt|What should students already know/have accomplished before the lesson is presented.}}

Prior to this lesson, students have been introduced to the following concepts:

* map datums
** know the difference between NAD27 and WGS84/NAD83 and can determine which one a topographic map uses
** are able to set the map datum on their GPS

* UTM
** can set their GPS to display UTM
** can read the 3 components of a UTM from it: Zone, Easting, Northing
** can convert a 13 digit UTM to a 6 digit UTM

* can identify the failure modes of a GPS

== Objectives ==
At the conclusion of this lesson
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

== Time Plan ==
Total Time: 75 minutes

Present Objectives
{{lesson slide||}}
''Break students up into small groups''
''(often best for instructor to chose groups to give students opportunities to work with others)''

{{lesson slide||}}
* Have each groups sign-out a radio, and one or more GPS (one per student if possible)
* Assign each group a call sign
* Do a radio test

{{lesson slide||}}
* ''Distribute GPS instructions''
* Review how to set up GPS
** Map Datum: NAD27 vs WGS84
** Grid system: UTM (Canada)

{{lesson slide||}}
* Review how to read UTM (Zone, Easting, Northing)

{{lesson slide||}}
* Review how to determine accuracy (e.g. 11m)
** waiting makes more accurate

{{lesson slide||}}
* Distribute maps (may have been given at start of course)
* Establish a return to class time

{{lesson slide||}}
* 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.

{{lesson slide||}}
* 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

{{lesson slide||}}
* 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?

{{lesson slide||}}
* 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
