What do the lines mean on a topographic map?
Contour lines are lines drawn on a map connecting points of equal elevation, meaning if you physically followed a contour line, elevation would remain constant. Contour lines show elevation and the shape of the terrain. They’re useful because they illustrate the shape of the land surface — its topography — on the map.
How do you read a topographic map scale?
Scale is the relationship between distance on a map and distance on the ground. It’s a ratio, like 1:24,000 — which means one inch on the map equals 24,000 inches (2,000 feet) on the ground. The larger the second number, the smaller the scale. The smaller the scale, the less detail on the map.

Topographical Map
When a contour line is drawn on a map it represents a given elevation. Every point on the map touching the line should be the same elevation. On some maps, numbers on the lines will let you know what the elevation is for that line. Contour lines next to each other will represent different elevations.
