dispersePoints

Disperse Points

Disperses (separates) the coincident points. The first point in a location preserves its coordinates. Every next point found in the same location is moved within user defined maximum offset distance from its original location.

Inputs:

A Point feature class
Maximum allowed offset - the duplicate points will move no further than this tolerance from their original location.
Dispersion method:
- Random - the points will be relocated randomly within the specified allowed distance
- Regular - the resulting points will be placed on a circle with radius the allowed offset distance.

Outputs:

New point feature class. Fields:
- The attributes of the original features will be preserved.
- [ET_Status] field will be added. The values in this field will indicate whether the resulting point is in its original position or has been relocated.

Parameters

Expression	Explanation
Function Name	DispersePoints
<input dataset>	A String representing the input layer. Must be of Polygon type.
<output dataset>	A String - the full name of the output layer.
<Tolerance>	A Double representing the Maximum allowed offset - the duplicate points will move no further than this tolerance from their original location.
<Disperse Mathod<	A string defining how the points will be dispersed. Valid values - "Random" or "Regular".

Running the function

ETGWPath used in the table below is the full path to ETGWRun.exe (E.G. "C:\Program Files\ETSpatial Techniques\ETGeo Wizards\ETGWRun.exe")

Language	Syntax
Python	subprocess.call([ETGWPath, "DispersePoints", "input dataset", "output dataset", "Tolerance", "Disperse Mathod"])
.NET using ETGWRun.exe	StartInfo.FileName = ETGWPath StartInfo.Arguments = "DispersePoints" "input dataset" "output dataset" "Tolerance" "Disperse Mathod"
.NET using ETGWOutX.dll	DispersePoints(input dataset, output dataset, Tolerance, Disperse Mathod)
ArcPy	arcpy.DispersePoints(input dataset, output dataset, "Tolerance", "Disperse Mathod")

Notes:

<> - required parameter
{} - optional parameter
See examples for Python , .NET or ArcPy
The argument separator for StartInfo.Arguments is space. If a string might contain a space, you need to double quote it.
