Which projection is recommended for accurate representation of large landmasses such as Russia?

The Lambert Conformal Conic projection is ideal for accurately representing large landmasses, particularly those that extend more in the east-west direction, such as Russia. This projection maintains conformality, which means it preserves angles and shapes over small areas. As a result, it is well-suited for aeronautical charts and for regions with a predominantly horizontal extent, allowing for relatively accurate representation of the landmass without significant distortion of shapes.

When working with large areas like Russia, which is significantly elongated east to west, this projection offers a more manageable solution compared to other projections. It effectively minimizes distortion in terms of shape and area, which is essential for tasks such as mapping, navigation, and geographic analysis where understanding the true shape of the land is important.

In contrast, other projections such as the Mercator are known to distort size, especially near the poles. The Equidistant projection is excellent for measuring distances but does not preserve shapes and is not optimal for large landmasses. The Planar projection, while giving a perspective view, does not provide a practical representation of vast regions like Russia. Hence, the Lambert Conformal Conic projection stands out as the most suitable for the accurate representation of large landmasses.
