Dissolve Polygons

Dissolves (aggregates) polygons based on user specified attributes. The resulting polygon data set does not contain multi-part polygons

An aggregated polygon feature class.Only the polygons with common boundaries that have the same values for the dissolve fields will be aggregated
Multi-part polygons will be created if specified by the user.
The attributes will be transferred according the user specified rules. For the fields with no specified update rule, date and blob fields, the aggregated feature will carry the attributes of the first feature.

Parameters

Expression	Explanation
Function Name	DissolvePolygons
<input dataset>	A String representing the input layer. Must be of Polygon type.
<output dataset>	A String - the full name of the output layer.
{Dissolve Fields}	A String representing a list (separated with ";") with the field names to be used for dissolving.
{Statistic Fields}	A String representing a list (separated with ";") with the field names for which statistics will be created. Example: "Field1 Sum;Field2 Max;Field3 Min"
{Create Multiparts}	A Boolean indicating whether the function will create multipart polygons.

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, "DissolvePolygons", "input dataset", "output dataset", "Dissolve Fields", "Statistic Fields", "Create Multiparts"])
.NET using ETGWRun.exe	StartInfo.FileName = ETGWPath StartInfo.Arguments = "DissolvePolygons" "input dataset" "output dataset" "Dissolve Fields" "Statistic Fields" "Create Multiparts"
.NET using ETGWOutX.dll	DissolvePolygons(input dataset, output dataset, Dissolve Fields, Statistic Fields, Create Multiparts)
ArcPy	arcpy.DissolvePolygons(input dataset, output dataset, "Dissolve Fields", "Statistic Fields", "Create Multiparts")

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.
