Why is Lambert map so important?

The Lambert map, also known as the Lambert conformal map, is important because it provides a way to represent the curved surface of the Earth on a flat plane while preserving angles, making it useful for navigation and cartography. It allows for accurate representations of geographical features and distances over small areas, which is critical for various applications such as aviation and meteorology. Additionally, the Lambert map's conformal properties help in minimizing distortion, making it a preferred choice for topographic and thematic maps.
