cleanContourGaps

Clean Contour Gaps

Cleans the gaps in a polyline dataset representing contours.

New polyline feature class. The gaps in the contours that a smaller then the selected tolerance are closed.

The function is designed specifically for contours, but it can be used on datasets representing different features.
Always inspect the results before accepting them as valid.

Input Contours

Resulting Polylines

Resulting Polylines with no gaps.

Parameters

Expression	Explanation
Function Name	CleanContourGaps
<input dataset>	A String representing the input layer. Must be of Polyline type.
<output dataset>	A String - the full name of the output layer.
<Gap Size>	A Double representing the maximum gaps to be removed (in the units of the input dataset).
<Elevation Field>	A String - the name of the field having the elevation value of the contours.

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, "CleanContourGaps", "input dataset", "output dataset", "Gap Size", "Elevation Field"])
.NET using ETGWRun.exe	StartInfo.FileName = ETGWPath StartInfo.Arguments = "CleanContourGaps" "input dataset" "output dataset" "Gap Size" "Elevation Field"
.NET using ETGWOutX.dll	CleanContourGaps(input dataset, output dataset, Gap Size, Elevation Field)
ArcPy	arcpy.CleanContourGaps(input dataset, output dataset, "Gap Size", "Elevation Field")

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.
