Geographic distortion refers to the misrepresentation of the true size, shape, distance, or direction of geographical features when they are projected from a three-dimensional sphere onto a two-dimensional map. This phenomenon is inevitable in map-making, leading to various projection methods that prioritize different aspects of accuracy depending on their intended use.

Geographical features are natural or artificial elements of the Earth's surface that define and distinguish different areas, influencing both the environment and human activities. They range from mountains, rivers, and lakes to urban landscapes and infrastructure, playing a crucial role in ecosystems, climate patterns, and cultural development.

Projection methods are mathematical techniques used to reduce the dimensionality of data by mapping it onto a lower-dimensional subspace, preserving essential features while discarding noise and redundancy. These methods are crucial in areas such as data visualization, machine learning, and numerical optimization, where they enhance computational efficiency and improve interpretability of complex datasets.

Intended use refers to the specific purpose or function that a product, system, or service is designed to fulfill, which guides its development, marketing, and regulatory compliance. It is crucial for ensuring that the product meets safety and performance standards and aligns with user expectations and legal requirements.
