A Scale
The map key gives one information about the symbols on a map.
A physical map of a genome gives relative positions of genes with distances measured in base pairs. This type of map shows the actual physical locations of genes on a chromosome and their distances from each other. It provides information on the linear order of genes and their physical distances along the chromosome.
The scale (distance scale) shows the relationship between lengths on the map and actual distances. The bar scale (if provided) shows a sample distance, typically for centimeters or inches on the map.

The part of a map that has information describing symbold used in the map is called a legend.
A map's legend provides key information about symbols or colors used on the map and what they represent, such as land features, roads, or landmarks. This helps users interpret and understand the map more effectively.
A Vegetation map gives you information about plants and tree in a given area

That is the scale of that map.

The part of a map that contains the information that explains what the map's symbols mean is called either the legend, key, or origin.
The scale bar on a map helps you measure distance. It represents the relationship between the distances on the map to the actual distances on the Earth's surface. By using the scale bar, you can accurately determine the distance between two points on the map.
