![]() DistancesĪre calculated between two points on a curved surface (the geoid) as opposed to two points on a flat surface (the Cartesian plane). Relatively small area (such as one UTM zone).Īccount for the actual shape of the earth (an ellipsoid, or more properly, a geoid). Euclideanīuffers are the more common type of buffer and work well whenĪnalyzing distances around features in a projected coordinate system, which are concentrated in a ![]() Euclidean buffers measure distance in a two-dimensionalĬartesian plane, where straight-line or Euclidean distances areĬalculated between two points on a flat surface (the Cartesian plane).There are two basic methods for constructing buffers: Euclidean and geodesic.

Creates buffer polygons around input features to a specified distance.
