equidistant projection

An equidistant projection is a way of mapping the Earth onto a flat surface that preserves distances from a central point to any other point on the map. Imagine drawing a map where you choose a specific location as the center, and then the straight-line distances from this center to other points are accurately represented. However, distances between other points that are not connected through the center may be distorted. This type of projection is useful when measuring distances from a single point, such as from a city to other locations, but it doesn't perfectly preserve all distances or shapes across the entire map.
