Question

Quizplus · Accepted Answer

Contour lines on topographic maps connect points of equal elevation, allowing for a three-dimensional representation of the landscape. Isoline maps, which represent data for a particular variable, may also use contour lines, but contour lines themselves are specifically designed to indicate elevation. Contour lines have been in use since the 19th century and continue to be a valuable tool for cartographers and other professionals. While they may not accurately represent negative values (e.g. below sea level), they can still be used to represent elevation changes above the waterline.
