Determines the distance between the farthest point of the error surface and the nearest point of the feature (point or line).
Syntax
intl gdlFarDistance( gdlHandle hGdl, gdlShape shape1, gdlShape shape2, intl* distance );
Arguments
hGdl
The gdlHandle initialized by gdlInitialize. Input.
shape1
The gdlShape object representing the error surface. Input.
shape2
The gdlShape object representing the object found using gdlFindNearest (or gdlFindNext). Input.
distance
The distance in feet. Output.
Return values
GDL_NOT_LICENSED
GDL_ERROR
GDL_OK
Prerequisites
gdlFindNearest
gdlGenerateErrorSurface
Alternates
gdlNearDistance
Note: To return the distance from the farthest point of the error surface to the nearest point
of the feature, the error surface must be passed in as shape1 and the feature as
shape2.
Notes
The following diagram illustrates the distance between the farthest point of the error surface and the nearest point of a line:
