A driving tour of North Dumfries gives us the opportunity to explore the use of topographic maps, compasses, and GPS units in a variety of settings. The students will triangulate their position using landmarks, plot a course from one location to another, measure linear and non-linear distances, determine slope, decide on optimal routes, and compare their results to the output of a GPS unit.
Key Concepts/Skills Developed:
- What is the UTM system?
- Map projections
- Key components of a topographic map
- Tricks to better use a topographic map
- Compass use: (Azimuth/quadrants, bearings/back- bearings, etc.)
- Finding GPS coordinates on a topographic map
