ETG_RasterContours

Contours from Raster

Interpolates contours from a raster. The contours can be created as PolylineZs with constant Z values representing the elevation.

New polyline feature layer. If the option for creating 3D contours is used the output will be PolylineZ layer.
A new field ET_Height is added to the attribute table. The values of this field contain the Z value for each contour.

The input format accepted are file based rasters - ERDAS IMAGINE or Tagged Image File Format (TIFF).
The .NET ToolBox for ArcGIS Desktop accepts also FileGDB Raster inputs.
The smooth polylines option might be time consuming.
The input raster must have a projected coordinate system.

Parameters

Expression	Explanation
Function Name	InterplolateContoursRaster
<input raster>	A String representing the input raster dataset.
<output dataset>	A String - the full name of the output feature layer (shapefile of FileGDB layer).
<BaseContour>	A Double representing the Z level of the contour from which to begin generation of contours.
<ContourInterval>	A Double representing the contour interval.
{Smoothness}	An Integer indicating the smoothness.
{ZContours}	A Boolean indicating whether the output to be Polyline or PolylineZ feature.

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, "InterplolateContoursRaster", "input raster", "output dataset", "BaseContour", "ContourInterval", "Smoothness", "ZContours"])
.NET using ETSRun.exe	StartInfo.FileName = ETSPath StartInfo.Arguments = "InterplolateContoursRaster" "input raster" "output dataset" "BaseContour" "ContourInterval "Smoothness" "ZContours""
.NET using ETSOutX.dll	InterplolateContoursRaster(input raster, output dataset, BaseContour, ContourInterval, Smoothness, ZContours)
ArcPy	arcpy.InterplolateContoursRaster("input raster", "output dataset", "BaseContour", "ContourInterval", "Smoothness", "ZContours")

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.
