Members

	All Properties Methods Inherited Non-inherited	Description
	AsPolygons	Converts the surface to a polygon feature class representing slope or aspect.
	Contour	Output contours based on the specified root value and interval.
	ContourList	Output a list of contours corresponding to the specified eleveation values.
	Domain	The interpolation domain of the surface.
	GetAspectDegrees	Returns the aspect at the specified location in degrees.
	GetAspectRadians	Returns the aspect at the specified location in radians.
	GetContour	Returns a countour passing through the queried point.
	GetElevation	Returns the z value of the specified location.
	GetLineOfSight	Computes the visibility of a line-of-sight from the observer to the target.
	GetProfile	Returns a polyline with z values interpolated from the surface.
	GetProjectedArea	Returns the projected area of the surface above or below an input z value.
	GetSlopeDegrees	Returns the slope at the specified location in degrees.
	GetSlopePercent	Returns the slope at the specified location in percent.
	GetSlopeRadians	Returns the slope at the specified location in radians.
	GetSteepestPath	Returns the steepest path downhill from the specified point.
	GetSurfaceArea	Returns the area measured on its surface above or below an input z value.
	GetVolume	Returns the volume above or below an input z value.
	InterpolateShape	Interpolates z values for a defined geometric shape.
	InterpolateShapeVertices	Interpolates z values for a defined geometric shape at its vertices only.
	IsVoidZ	Returns TRUE if the passed value is equal to the surface's void value.
	Locate	Returns the intersection of the query ray and the surface.
	LocateAll	Returns the distances of intersections of the query ray and the surface.
	QueryNormal	Returns the vector normal to the specified triangle.
	QueryPixelBlock	Derives slope, aspect, hillshade, or elevation from the input surface and writes the result to the provided PixelBlock.
	QuerySurfaceLength	Returns the length of an input polyline measured on the surface.
	Z	The surface Z = f(x,y).
	ZFactor	Multiplication factor applied to all z values to provide unit-congruency between coordinate components.
