What do the black lines and dots in the map represent?
Cartographers use symbols to represent geographic features. For example, black dots represent cities, circled stars represent capital cities, and different sorts of lines represent boundaries, roads, highways, and rivers. Colors are often used as symbols.
What do dashes mean on a map?
public rights of way
Ordnance Survey maps use coloured dashes to denote public rights of way, even where there may be no actual visible path in reality. Other symbols are used to indicate actual paths that should be found on the ground. The black dashes on an OS map can be either a single line or 2 parallel lines.
What does the black dot in the river indicate?
Blank dots represent villages and their relevant gauging stations. Major tributaries and streams are also depicted [Colour figure can be viewed at wileyonlinelibrary.com]
What do dashed contour lines represent?
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 the red dashed lines on maps?
Tip: You can find road closures marked with a dotted red line where the road is closed. Tip: When possible, the colored lines on the map match the transportation agency’s color system.
What do the blue squiggly lines represent?
Wavy blue lines that appear under text in a Word document indicate that the Format Consistency Checker is turned on and is functioning in the background as you type. The lines indicate that the Format Consistency Checker has detected an inconsistency that you may want to look at and to correct.
What is the red line on the map called?
The colors of the lines usually indicate similar classes of information: topographic contours (brown); lakes, streams, irrigation ditches, and other hydrographic features (blue); land grids and important roads (red); and other roads and trails, railroads, boundaries, and other cultural features (black).
What do the Blue Lines on a topographical map mean?
Rivers, of course, are represented by blue lines that will run through the center of the V-shape. Sometimes called draws, the V-shape of this feature always points towards their peak. You can also use a topographic map to determine the direction the river is flowing.
What do the different colors represent on maps?
Road maps and other general-use maps are often a jumble of color, such as with the following schemes: Blue: lakes, rivers, streams, oceans, reservoirs, highways, and local borders. Red: major highways, roads, urban areas, airports, special-interest sites, military sites, place names, buildings, and borders. Yellow: built-up or urban areas.
What do the black dots on a map mean?
Black also shows boundaries, with differing types of dashes and/or dots used to represent the type of boundary: international, state, county, or other political subdivision. Physical maps use color most dramatically to show changes in elevation.
How are units of measure represented on a map?
The representative fraction does not have specific units. It is shown as a fraction or ratio —for example, 1/1,000,000 or 1:1,000,000. This means that any given unit of measure on the map is equal to one million of that unit on Earth. So, 1 centimeter on the map represents 1,000,000 centimeters on Earth, or 10 kilometers.
