Maps being two-dimensional can lead to distortions in representing the Earth's three-dimensional surface, affecting the accuracy of distances, areas, and shapes. This limitation can mislead users, especially in applications like navigation or land use planning, where precise spatial relationships are critical. Additionally, important features like elevation and terrain are not adequately conveyed, potentially oversimplifying complex geographical realities.

Distortion
Maps covering a large area suffer from "barrel distortion". In the usual layout of maps, East-West distances are compressed near the equator and exaggerated as you move towards the poles.
The Earth’s three-dimensional surface is commonly represented in two dimensions through maps and globes. Maps use various projections, like the Mercator or Robinson projection, to depict the curved surface of the Earth on flat surfaces, while globes provide a more accurate representation of geographical features. These representations help visualize and understand spatial relationships, distances, and orientations on the Earth's surface.
Elevations (heights) are not easily represented.
Distortion
The main problem is that the earth is approximately spherical and therefore maps covering large areas suffers from distortions due to projection from 3-D to 2-D.
