The USGS (U.S. Geological Survey) publishes a set of the most commonly used topographic maps of the U.S. called US Topo that are separated into rectangular quadrants that are printed at 22.75"x29" or larger. A topographic map is a detailed, accurate graphic representation of features that appear on the Earth's surface, including: human-made (such as roads and railways, provincial and national parks, place names, municipal and township boundaries, lots and concessions) natural (such as lakes and rivers, falls, rapids and rocks, wooded areas, wetlands) Question. 5) The dots are connected with a smooth curved line. Point A represents a location on Earth's surface. Topographic maps have contour lines that connect points of identical elevation above sea level.

For questions 2 through 6, refer to Map 3.2. Therefore the river flow is from south to north with tributaries flowing down the draws (gullies) on either side of the valley. This video explains how to determine the direction in which a stream is flowing on a topographic map. The horizontal distance between contours, on the other hand, is determined by the steepness of the landscape and can vary greatly on a given map. Site identification number Each site in the USGS data base has a unique 8- to 15-digit identification number.
