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 surface area pf the Earth is on a sphere, not a flat surface.
Two-dimensional maps display spatial information in a flat format, representing geographical features like landforms, roads, and boundaries. They use symbols, colors, and scales to convey data about elevation, vegetation, and urban development. These maps are essential for navigation, urban planning, and understanding spatial relationships in various contexts. Overall, 2D maps simplify complex spatial data for easier interpretation and analysis.

Distortion
Earth is three-dimensional, but maps are two-dimensional.
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.
A three dimensional map of terrain is called a raised relief map.
Planar projection
Two-dimensional maps of Earth have distortions because they attempt to represent a three-dimensional surface (the Earth) on a flat plane. This distortion occurs due to the challenge of converting a curved surface onto a flat surface. Different map projections have different advantages and trade-offs in terms of preserving features like shape, area, distance, or direction.
such a map is a three dimensional representation of the terrain

Models are three dimensional prototypes that help the viewer see a smaller scale of a detailed area. Maps are usually one dimensional and contain directions from a view that would not show great detail.
Isoline maps are a two dimensional representation of a three dimensional model. An isoline map gives you a picture of the concentration of people. :)
Physical relief maps show the terrain and elevation of a specific geographic area. They use colors and contour lines to depict the topography, such as mountains, valleys, and plains. These maps provide a visual representation of the three-dimensional landscape on a two-dimensional surface.
