From Pathfinder Wiki

Other than showing elevation via the contours, you can also expect a topographic map to show any important landmarks, such as rivers, lakes, and roads. They will often also show railroad tracks and major power lines (and their towers). Power lines are especially handy because the towers are visible from great distances and each represents a point on a map (whereas a road or river would represent a curved line). These attributes make them ideal for pinpointing position.
