Background
Overview
Understanding map projections is crucial for interpreting geographical data, analyzing spatial relationships, and comprehending the limitations of maps. It is a fundamental concept in physical geography and cartography, often tested in both Prelims (e.g., properties of specific projections) and Mains (e.g., implications of different world maps for geopolitical understanding).
Map projections are systematic transformations used to represent the curved, three-dimensional surface of the Earth on a flat, two-dimensional plane. This process inherently introduces distortions in properties such as area, shape, distance, or direction, as a sphere cannot be perfectly flattened without stretching or tearing.
