In Central Place Theory, what does isotropic plane mean?

• A. A flat surface with uniform properties in all directions
• B. A curved surface with variable elevation
• C. A plane with uniform properties in all directions
• D. A landscape with barriers and irregularities

Answer: (C)

Isotropic plane means a surface where movement costs and conditions are the same in every direction. In Central Place Theory, this idealized, uniform space lets central places serve their surrounding areas equally in all directions, which makes the market areas tend toward regular shapes (often hexagons) because distance is the only factor shaping reach. So the best description is a plane with uniform properties in all directions. The idea of a curved surface or a landscape with barriers would introduce directional differences in travel or accessibility, breaking that uniformity and disrupting the neat hexagonal pattern. A flat surface with uniform properties is essentially describing the same idea, but the term plane is the precise geometric way to express the concept used in the theory.
