connectUnstructuredPoints

Connects each point of a point dataset to its closest neighbors to create polylines. The function does not require attributes that define which points should pertain to a single polyline or order of the points within the polylines (if your point data has such attributes use the Point To Polyline function instead). The function uses a robust algorithm and can be applied on datasets containing up to 2 million points.

Inputs:

A Point feature layer
Cutoff distance - the maximum distance to search for neighbor points.
Avoid Loops option (see notes and examples below)

Outputs:

A new Polyline feature class.

Notes:

If the distance from a point to the closest point is larger than the Cutoff distance then no link will be created between the two points
If there are coincident points in the input dataset, the duplicates will be ignored.
If the Avoid Loops option is not selected each point will be connected to its 2 closest neighbors (provided that the distance between the point and the neighbors is less than the Cutoff distance)
If the Avoid Loops option is selected, the function will try to create longest non intersecting polyline possible.

Examples:

Source Points	Result - Avoid Loops NOT selected	Result - Avoid Loops selected

Command line syntax

ET_GPConnectUnstructuredPoints<input_dataset> <out_feature class> <cut_off>{avoid_loops}

Parameters

Expression	Explanation
<input_dataset>	A Point, Polyline or Polygon feature class or feature layer
<out_feature class>	A String - the full name of the output feature class (A feature class with the same full name should not exist)
<cut_off>	A Double representing the maximum distance between two points to be considered neghbors - in the units of the spatial reference of the input dataset
{avoid_loops}	A Boolean indicating whether the function will try to avoid loops when connecting the points (see example above).
