A scale is necessary

A scale is necessary on maps to provide a proportional representation of distances on the Earth’s surface. It indicates the relationship between a unit of measurement on the map and the corresponding distance in the actual world. This helps users understand the size and relative distances of features on the map, aiding in accurate navigation and measurement. Scales can be represented as a bar scale (graphic scale) or a verbal scale, providing a critical reference for interpreting distances and planning activities based on the map.
