ETG_ZonalMinMaxPoints

Zonal Min/Max Points

Locates in the input raster the cells with minimum and maximum values within each of the input polygons and extracts them in a new points dataset.

Input Polygon feature dataset
Full name of the output Point feature dataset.
An input raster dataset.
A string indicating the points to be extracted - "min" specifies the minimum values within the polygon to be extracted, "max" is for maximum values, anything else will extract both minimum and maximum values.

The following new fields will be added to the output point feature dataset.
- ET_PgID - The ID of the polygon within which the point is.
- ET_Value - The value of the raster in the point location.
- ET_MinMax - A string indicating if it is a Max or Min value within the polygon.

Parameters

Expression	Explanation
Function Name	ZonalMinMaxPoints
<input polygons>	A String - full path to the Input Polygon dataset.
<output points>	A String - the full path to the output Point dataset.
<input raster>	A String - full path to the input raster dataset.
{option}	A String indicating the points to be extracted. See description above.

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, "ZonalMinMaxPoints", "input polygons", "output points", "input raster", "option"])
.NET using ETSRun.exe	StartInfo.FileName = ETSPath StartInfo.Arguments = "ZonalMinMaxPoints" "input polygons" "output points" "input raster" "option"
.NET using ETSOutX.dll	ZonalMinMaxPoints(input polygons, output points, input raster, option)
ArcPy	arcpy.ZonalMinMaxPoints("input polygons", "output points", "input raster", "option")

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.
