466 - Define the principle of friction of distance and geographic models that are based on it (e.g., gravity models, spatial interaction models)

Concepts

• [CF6-4] Metrical relationships: distance and direction
  Relationships between spatial features that define their relative position. Spatial autocorrelation is a fundamental principle based on Tobler’s first law of geography, which states that locations that are closer together are more likely to have similar values than locations that are farther apart.
