What is the black dotted line on a topographic map?
Features are often shown by solid, dashed, or dotted lines of various colors: brown topographic contours; blue lakes, streams, irrigation ditches, etc.; red land grids and important roads; and black for other roads and trails, railroads, boundaries, etc.
Are contour lines dotted?
Sometimes intermediate contours are present in flatter areas; these can be dashed or dotted lines at half the noted contour interval.
What do dashed contour lines mean?
Finally, when the terrain is expansively flat, cartographers will often include supplementary contour lines, which are dashed lines indicating an elevation that is half of the elevation between the contour lines surrounding it. They are typically found where there is little change in elevation.
What are dotted lines on a map?
Black dashed/dotted lines: There are countless versions of dash and dot line combinations. They can be used to designate the calculated centerline of a road, the actual centerline or limits of the pavement, they may represent building and set back lines, or they can be used to show the line between 2 parcels.
What does the dotted line on the map show answer?
Answer: Dotted lines are indicated as borders for provinces or states.
How far apart are contour lines on a map?
Contour lines are generally illustrated as a brown line. Individual contour lines on a topographical map are a fixed interval of elevation apart known as a contour interval. Common contour intervals are 5, 10, 20, 40, 80, or 100 feet.
What does a dotted road on a map mean?
The dotted line is not directions. It just indicates that you can’t get to the destination by car so it brought you to the closest place and you’ll have to walk the rest of the way.
What do the lines mean on a topographic map?
Put simply, contour lines mark points of equal elevation on a map. Topographic maps use a combination of colors, shading and contour lines to represent changes in elevation and terrain shape. Essentially, topographic maps represent the three-dimensional landscape of Earth within the two-dimensional space of a map.
What does a dashed line represent?
In visual language, the dashed line gives us a way to express the idea that something is not concrete. Something impermanent. It may be temporary; it may not currently exist (it will in the future or it did in the past); or it may be invisible or hidden. One way or the other, it represents what it is—not solid.
What are the symbols on a topographic map?
Topographic maps use symbols to represent natural and human constructed features found in the environment. The symbols used to represent features can be of three types: points, lines, and polygons. Points are used to depict features like bridges and buildings.
What kind of map uses contour lines to illustrate elevation?
A map with contour lines on it is called a topographic map. Topographic maps use a combination of colors, shading and contour lines to represent changes in elevation and terrain shape. Essentially, topographic maps represent the three-dimensional landscape of Earth within the two-dimensional space of a map.
What is the distance between contour lines?
The vertical distance between adjacent contour lines is known as the CONTOUR INTERVAL. The amount of the contour interval is given in the marginal information. On most maps, the contour lines are printed in brown. Starting at zero elevation, every fifth contour line is drawn with a heavier line.
What are the bold lines on topographic maps?
On topographic maps, every fifth contour line is in bold (called an “Index Line”), where you’ll find the elevation indicated. When planning out a hike, one of the most important things to pay attention to is how close the contour lines are spaced.
What are the different types of contour lines?
The main types of lines are horizontal lines, vertical lines, perpendicular lines and parallel lines. Other categories of lines include diagonal lines, curved lines, contour lines and continuous lines.
