Distance on maps is defined by scale, so a survey map should show both a graphic scale and a numerical scale. The graphic scale (bar scale) lets you measure distances directly on the map with a ruler, and it remains usable if the map is printed larger or smaller. The numerical scale provides the exact conversion between map units and ground units (for example, 1 inch equals a certain number of feet), which is essential for precise calculations and for readers who prefer numeric data. Having both scales ensures distances can be read visually and computed accurately, no matter how the map is reproduced or viewed. Time scales or color scales don’t convey distance, and saying no scale is required would leave distances ambiguous.
