Parameters

Expression Explanation
Function Name SnapPoints
<input dataset> A String representing the input layer. Must be of Point type.
<reference dataset> A String representing the reference layer. Must be of Polyline type
<output dataset> A String - the full name of the output layer.
< SnapTolerance> A Double representing  the Snap Tolerance to be used. The units of the tolerance are the units of spatial reference of the input dataset if KeepSourceSref = TRUE. Otherwise - the units of spatial reference of the reference dataset.
{snap option} A String indicating the snap option to be used. Valid inputs: "Vertex" or "Nearest". Default = "Nearest"
{snapToZ} A Boolean indicating whether to snap to Z values (if the reference dataset has Z values). Default = False.
{KeepSourceSref} A Boolean indicating whether the output to have the spatial reference of the input layer. If False or 0, the spatial reference of the reference layer will be used.

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, "SnapPoints", "input dataset", "reference dataset", "output dataset", " SnapTolerance", "snap option", "snapToZ", "KeepSourceSref"])
.NET using ETGWRun.exe StartInfo.FileName = ETGWPath
StartInfo.Arguments = "SnapPoints" "input dataset" "reference dataset" "output dataset" "SnapTolerance" "snap option" "snapToZ" "KeepSourceSref"
.NET using ETGWOutX.dll SnapPoints(input dataset,reference dataset, output dataset, SnapTolerance, snap option, snapToZ, KeepSourceSref)
ArcPy arcpy.SnapPoints(input dataset, reference dataset, output dataset, "SnapTolerance" , "snap option", "snapToZ", "KeepSourceSref")
