When cartographers represent the three dimensional earth in two dimentions?

When cartographers represent the three-dimensional Earth in two dimensions, they use various projection methods to translate the curved surface onto a flat plane. Each projection type, like Mercator or Robinson, prioritizes different aspects such as area, shape, or distance, often resulting in distortions. These projections allow for easier navigation and visualization but require careful selection based on the map's intended purpose. Ultimately, the goal is to balance accuracy and usability in representing geographic information.
