A bar scale helps you find distances between places
Road maps are used for directing people if they get lost. Another word for a road map is called a melways.
The two main reference lines used in locating places on Earth are the Equator, which divides the Earth into the Northern and Southern Hemispheres, and the Prime Meridian, which divides the Earth into the Eastern and Western Hemispheres. Additionally, lines of latitude (parallels) and longitude (meridians) help pinpoint specific locations on the Earth's surface.
When locating a position on a map while being on a linear feature, the method typically used is called triangulation. This involves identifying your location based on two or more reference points, which can be other known locations on the map. By measuring angles or distances from these points, you can determine your precise position along the linear feature. This approach is commonly used in navigation and surveying.
The azimuthal projection is most useful for showing distances between two points on the Earth. This type of map projection represents the globe on a flat surface by projecting it from a specific point, allowing for accurate measurement of distances from that point to any other point on the map. However, for more comprehensive distance measurements across larger areas, the great circle distance method can be used in conjunction with a globe.
The North Star is at the north always so it is used fir locating directions.
A bar scale is a graphic scale that visually represents the ratio between distances on a map or drawing and actual distances on Earth. It can be used to estimate the actual size of features or distances represented on the map.
They are most commonly used for showing and pleasure riding. They are also used for racing, therapy, police work, and in some places they are still used for plowing, hauling logs and other work like they used to.
i am pretty sure that camels were used for log distances in Egypt.
