Who uses topography maps?
Hikers, campers, snow skiers, city and county planners, the Fish and Wildlife Service, Forest Service, miners, loggers, highway planners and construction workers, travelers, surveyors, geologists, engineers, and scientists are just a few of the people who use topographic maps. Knowing the shape of the terrain enables a hiker to plan a hike. Highway planners determine the best routes for highways knowing the cut and fill areas. Surveyors locate benchmarks, and geologists locate their actual positions relative to the map and can determine if changes to the land have occurred.
