What are topo maps?
term topo map is short for length topographic map . Topo maps, also known as contour maps, are maps that show the Earth's surface in a number of outline lines. The outline lines provide a reference to an increase in any point and the lines are drawn in a number of intervals that show the heights of mountains, ocean depths and slopes. Topo maps usually provide a reference area of any given map and outline lines are drawn from this point. For example, in Hawaii, a reference surface would be the level of the sea, while in Colorado it could be a low river valley or the lowest point in the state, depending on the size of the map. Heights are usually printed on topo maps just along the edge of the line. The outline lines drawn very close to each other indicate steep slopes, while those that are little and far between them in general soil levels.
linIE Outline on topo maps varies significantly at the contour interval. The outline interval indicates the steepness of the slope. For example, on the Topo map, representing a sharp mountain class, the contour interval can be 100 feet (30.48 meters) or more, which means that there is a height of 100.48 meters between each contour line. Topo maps showing the soil level can only have a contour interval of only 10 feet (3.48 meters).
Topo maps are not limited to outline lines for mountains, slopes and planes. Other geographical data are also usually printed on topo maps such as rivers, lakes and channels, as well as on important roads, railways, real estate and hiking trails. Topo Maps Evan has symbols for camps and buildings, although the highly populated area is simply shown by a darker color shade over the map; In this way, altitudes can still be displayed under the streets of the city and structures.
Outline lines on topo maps are generally drawn by brown, important roads in red, others withIlnice and trails in black and waterway in blue. Topo maps designed to display slopes and outlines of ocean DNA have outline lines known as bathymetric outlines. No wonder these contour lines are drawn in blue or black.
