thinPoints

Thin Points

Reduces the number of points in a point dataset based on their spatial location.

Points that are closer to each other than the tolerance specified will be converted to a single point.
The values in the field specified will be summarized for each cluster and saved in the point representing this cluster.
Optionally a copy of the original layer will be created. The attribute table will have a field enabling a back link from the generalized points to the original ones to be created.

A Point feature class
Generalization tolerance - should be smaller than 20% of the smaller side of the extent envelope of the input dataset.
Data field - if specified the output feature class will have a field in which the value for each resulting point will be the sum of the values of the points pertaining to this cluster.

New point layer. Fields:
- [ET_Count] - the number of points from the input feature class represented by each output point
- [ET_Link] - added only if the "Add Link from the original points" option is selected.
Optional point layer - a copy of the original points with a link field added.

If no Generalization tolerance of 0 is specified only the exact duplicates will be removed

Input Dataset

Result Dataset labeled with the number of points they represent (ET_Count field)

Expression	Explanation
Function Name	ThinPoints
<input dataset>	A String representing the input layer. Must be of Point type.
<output dataset>	A String - the full name of the output layer.
<tolerance>	A Double representing the Generalization tolerance (in the units of the spatial reference of the input dataset) to be used
{LinkName}	A String representing the full name of the optional output layer.

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, "ThinPoints", "input dataset", "output dataset", "tolerance", "LinkName"])
.NET using ETGWRun.exe	StartInfo.FileName = ETGWPath StartInfo.Arguments = "ThinPoints" "input dataset" "output dataset" "tolerance" "LinkName"
.NET using ETGWOutX.dll	ThinPoints(input dataset, output dataset, tolerance, LinkName)
ArcPy	arcpy.ThinPoints(input dataset, output dataset, "tolerance" , "LinkName")

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.
