What is a bar scale on a map?

Scale bars, also called bar scales, look like a small ruler on or near the map. If the distance between the two ticks is longer than the scale bar, the reader can lay it next to the scale bar multiple times to determine the total distance. A scale bar can be used like a small ruler to determine distances on maps.

What is a bar scale?

A linear scale, also called a bar scale, scale bar, graphic scale, or graphical scale, is a means of visually showing the scale of a map, nautical chart, engineering drawing, or architectural drawing. A scale bar is common element of map layouts.

What is the legend or key?

Definition: A key or legend is a list of symbols that appear on the map. For example, a church on the map may appear as a cross, a cross attached to a circle, a cross attached to a square. The symbol Sch means School. Symbols and colours can also represent different things like roads, rivers and land height.

What is the purpose of a legend and scale on a map?

What is the purpose of the legend on a map?

A map legend or key is a visual explanation of the symbols used on the map. It typically includes a sample of each symbol (point, line, or area), and a short description of what the symbol means. For example, a short segment of a blue sinuous line may be labeled ‘rivers’.

How is a bar scale used?

To use the bar scale, you need to measure how long one segment of the bar is on your ruler. So, if 1 cm on the bar represents 10 m on ground, and the distance you measure on the map is 3 cm ( 3 cm ÷ 1 cm length of segment = 3 segments) then the real distance on the ground is 3 × 10 m = 30 m.

What do scale bars mean in ArcGIS Pro?

A scale bar is a line or bar divided into parts. It is labeled with its ground length, usually in multiples of map units, such as tens of kilometers or hundreds of miles. Scale bars are associated with a map frame in a layout. If the map scale for that map frame changes, the scale bar updates to remain correct.

What does a legend do on a map?

Legends display the translation of the most important attributes on a map. The main idea is that a legend only includes the information on a map that is not inherently understood by the map reader. Layers like roads, counties, or labeled icons are usually omitted from the legend.

Which is more accurate bar scale or verbal scale?

Note that in such situations the original ratio scale (or verbal scale) of the map would not be accurate anymore. However the advantage of bar scale is that it would shrink or expand consistently with the map in case of any resizing, and therefore will remain an accurate representation of the map scale.
