On topographic maps, V-shaped contour lines that point downhill indicate sharp, narrow ridge lines. Ridge lines help people recognize areas of high and low ground when hiking, fishing, hunting or engaging in other outdoor activities.Know More
Topographic maps provide a two-dimensional view of specific landscapes and regions. Using these maps, people can determine high and low ground for camping, hunting and fishing. Topographic maps also include mountain ranges, valleys and other landmarks, such as roads, railways, lakes, streams, buildings, homes, quarries and crop fields.
Contour lines, such as ridge lines, indicate how steep or how much of a slope exists in a specific area. This is important information for those who want to walk or camp in an unknown area. An understanding of how much the ground rises and falls allows people to find the easiest path through an area. For example, approaching a ridge at a right angle typically results in a steep, difficult climb to the top and then a sharp decline to the bottom. Following the natural form of the ridge results in a more level and less-difficult journey. Without a topographic map, it is impossible to view the entire ridge line accurately and choose the correct or best path through it.Learn more about Maps & Cartography
Contour lines on a map indicate elevation or depth. Numeric notations on contour lines refer to the level of elevation, or height above sea level.Full Answer >
The lines commonly seen on weather maps are called isobars. They are used to show areas that have the same barometric pressure, either at a given time or on average over a certain period.Full Answer >
An index contour is one of the ways that vertical dimension, or vertical scale, is demonstrated on a topographical map. The index contour represents the vertical scale on a map region by a thick solid line with the various elevations printed on it. Thinner solid lines, called intermediate contours, are used to depict lesser elevations that are referenced to the height information provided by the map's legend.Full Answer >
Topographical maps are essential for the study and measurement of various terrains. One of their defining features is the presence of contour lines, which represent the elevation levels of a landscape. The bottom of a topographic map shows the height interval between each contour line, the scale of the map and rulers representing various units of distance.Full Answer >
