Establish the grid, plot the elevations $($the decimal point is the plot point from Table $8-5,$ and interpolate the data to establish contours at $1-m(1-ft)$ intervals. Scale at $1$:$500$ for metric units, or $1in.=10ft$ or $15ft$ for foot units. Use pencil.

Compute the interior angles of the traverse and check for geometric closure, that is $(n-2)180($see Table $8-5).$

Plot the traverse, using the interior angles and the given distances. Scale as in Problem $8\mathrm{.}1($see Table $8-7).$
