Get some graph paper or draw a grid with 50 mm x 50 mm squares as shown below. This will represent the grid we laid out that was a 10 m x 20 m block (5m x 5m squares). Label the grid lines (A to E and 1 to 3) Plot your grid RLs and draw in the contour lines. The contour interval you should use is 0.20m. Your contour lines should start at 16.20. * Remember to submit your completed booking sheet for task 1.6 with your contour plan.
