Historical Maps And Cartography Questions
Contour lines in topographic maps are lines that connect points of equal elevation. They represent the shape and relief of the land by indicating the height and steepness of the terrain. Contour lines are typically drawn at regular intervals, such as every 10 meters or every 100 feet, and can be used to determine the elevation of specific locations, identify valleys, ridges, and other landforms, and plan routes for navigation. The spacing between contour lines indicates the slope of the land, with closely spaced lines indicating steep slopes and widely spaced lines indicating gentle slopes.
