Average Points

Creates new points at the mean positions of point clusters of the same feature code. The point clusters can be selected by block or point ID's combined with search tolerences. The original points may be optionally deleted.

This feature is particularly useful if multiple positions have been created for the same object.

The Maintenance/Average Points command is selected from the Plan View Utilities task.

Average Points dialog box

Item	Used to
Horizontal Tolerance (+-):	Key in the East and North difference tolerance. Points which are within the specified distance of each other in both the East and North directions will be averaged, provided however that they are also within the vertical tolerance (if specified). This field must contain a value to proceed.
Vertical Tolerance (+-):	Key in the Elevation difference tolerance. Points which are within the specified elevation difference of each other will be averaged, provided however that they are also within the X & Y tolerance.
Prefix or Suffix	Specify that any average points created are to have the entered prefix or suffix for easier identification. The prefix or suffix will be used in combination with the next available poit ID when the average points are created.
Points	Enter the point identifiers to be averaged. Key in or select the point identifiers. Alternatively enter two point identifiers separated by two dots to specify a range. If the system is in Block mode, leaving this field blank will select all points within the block definition; entering a range will select those points which are both within the range and defined by the block.
Delete Original Points	Nominate that the original points used in computing the average points are to be deleted. If points are deleted, any lines attached are relocated to the average point. Arc or circle points can only be deleted if the resulting arc or circle point position does not jeopardise the mathematical integrity of the arc or circle.
OK	Perform the averaging operation. The operation may take a considerable period of time to complete, particularly for large data sets.
Cancel	Close the dialog box.

During the averaging process, clusters of points with the same code and within tolerance of each other are located and reported. An average point of the same feature code is created for each cluster.
