contour map

A map that displays the hills and dales of a site as determined by a topographical survey. The contours of the land are represented by curved lines along which the height above sea level is relatively constant. The map will contain a linear scale indicating the dimensions of the site, and a contour scale indicating the elevation difference between contour lines,such as 5 feet. Lines that are widely spaced indicate a slow change in elevation; lines that are closely spaced indicate a rapid change in elevation.
