Point Global Snap

Snaps the features of a point layer to another layer (Point, Polyline or Polygon)

A point layer to be snapped
A reference layer - point, polyline or polygon
Snap tolerance
Snap options
Keep Input Spatial Reference - If selected the output will have the spatial reference of the input dataset, else the spatial reference of the reference dataset will be used

A point layer - the points from the source layer will be moved to snap to the features of the Snap Layer (if within the snap tolerances)

Vertices: The points will be snapped to the nearest vertex of the nearest feature from the Snap layer
Nearest: If there is a vertex closer than the snap tolerance to the point to be snapped, the point will snap to it, otherwise it will snap to the nearest edge.
Snap to reference Z values (only if the input and output are Z enabled)

The units of the Snap Tolerance should be the units of spatial reference of the input dataset if the user has selected the Keep Source Spatial Reference option. Otherwise - the units of spatial reference of the reference dataset.
The Source and the Snap datasets can have different spatial references as long as they have the same Geographic Coordinate systems.

Before Snap

After Snap - Option: Vertex

After Snap - Option: Nearest

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.

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")

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.
