ETG_CleanContourGaps

Clean Contour Gaps

Running programmatically

Cleans the gaps in a polyline dataset representing contours.

Inputs:

A Polyline dataset
A field representing the elevation value of the contours
Tolerance - the gaps smaller than this tolerance will be closed.

Outputs:

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

Notes:

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.

Example :

Input Contours

Resulting Polylines

Running Programmatically

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.
<Elevation Field>	A String - the name of the field having the elevation value of the contours.
<Gap Size>	A Double representing the maximum gaps to be removed (in the units of the input dataset).

Running the function

ETSPath used in the table below is the full path to ETSRun.exe (E.G. "C:\Program Files\ETSpatial Techniques\ETSurface\ETSRun.exe")

Language	Syntax
Python	subprocess.call([ETSPath, "CleanContourGaps", "input dataset", "output dataset", "Elevation Field", "Gap Size"])
.NET using ETSRun.exe	StartInfo.FileName = ETSPath StartInfo.Arguments = "CleanContourGaps" "input dataset" "output dataset" "Elevation Field" "Gap Size"
.NET using ETSOutX.dll	CleanContourGaps(input dataset, output dataset, Elevation Field, Gap Size)
ArcPy	arcpy.CleanContourGaps(input dataset, output dataset, "Elevation Field", "Gap Size")

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.
