IProximityOperator Interface

Provides access to members that find the 2D distance between two geometries.

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Proximity operators are used to find the distance between two geometries or the distance from a given point to the nearest point on another geometry.

	Name	Description
	QueryNearestPoint	Copies into 'nearest' a point on this geometry nearest to the input point.
	ReturnDistance	Returns the minimum distance between two geometries.
	ReturnNearestPoint	Creates and returns a point on this geometry nearest to the input point.

Classes	Description
BezierCurve	A cubic Bezier curve defined between two points; optionally has measure, height and ID attributes at each endpoint.
CircularArc	A portion of a circle that connects two points optionally has measure, height and ID attributes at each endpoint.
EllipticArc	A portion of the boundary of a 2D ellipse that connects two points; optionally has measure, height and ID attributes at each endpoint.
Envelope	A rectangle with sides parallel to a coordinate system defining the extent of another geometry; optionally has min and max measure, height and ID attributes.
Line	A 2D straight line between a pair of 2D endpoints; can optionally have height, measure and ID attributes at each endpoint.
MultiPatch	A collection of surface patches.
Multipoint	An ordered collection of points; optionally has measure, height and ID attributes.
Point	A two dimensional point, optionally with measure, height, and ID attributes.
Polygon	A collection of rings ordered by their containment relationship; optionally has measure, height and ID attributes.
Polyline	An ordered collection of paths; optionally has measure, height and ID attributes.
