Map Projections

All flat maps have some distortion in their representation of: Distance Shape Area Or

All flat maps have some distortion in their representation of: Distance Shape Area Or direction.

Equal-area (or equivalent) projections: maps that maintain area but distort other properties. Conformal

Equal-area (or equivalent) projections: maps that maintain area but distort other properties. Conformal (or orthomorphic) projections: maps that maintain shape but distort other properties (it is impossible to have a projection that is both conformal and equal area). Azimuthal projections: maps that maintain direction but distort other properties. Equidistant projections: maps that maintain distance but distort other properties. Types of Projections
