Contour Lines

Contour lines are a representation of the slope of the ground surface. They are usually drawn in 1, 2, 5, 10, or 20 foot intervals. A surveyor takes elevation measurements in the form of a grid across the property and then interpolates between those shots to determine where even foot contour lines should run. That process is continued all across the property until the contour lines drawn bend and turn representing the various natural ups and downs the property has.
