tape measure
metric graph paper
erasable soft pencil (No. 2) and eraser
Brunton (supplied)
AIM: Draw a map of all the footpaths in the quadrangle
to scale
1. Walk the back of the Geology building and measure its length in paces.
Question: How many paces long is it?
Calculating the Height of the Geology Building
3. Walk 30 paces from the back door of the building toward the west along the path,
Measure the angle to the top of the building
Use the following equation to estimate the height of the Geology Building:
Building height (m) = 30 paces (expressed as meters!) x tan (measured angle)
4. Position a transit 30 paces away from the building and re-estimate the angle to the top of the building. What is the difference in the building height compared to question 3?
Double-check these measurements by walking the diagonal distance across the quadrangle and using Pythagoras’ Theorem.
6. Calculate a scale that will allow you to fit the length and width of the quadrangle on your paper. The edges of the buildings should show on your map. Note the names of each of the buildings.
Mark the direction of N on your map (use your Brunton)
8. Complete a map of the quadrangle and all its features. Include a scale, orientation, significant features in the quadrangle and a legend. Hand in all your work plus a final inked map on drawing paper.
Note: Place the rear wall of the Geology building on the right side of your graph paper
