generalizePolygons

Generalizes ( reduces the number of vertices required to represent a polygon ) the features of a polygon layer using the Douglas-Poiker algorithm. Preserves the polygon topology

Inputs:

A polygon feature class
Generalization Tolerance (maximum offset) - the maximum distance that the generalized polyline will differ from the original one

Outputs:

New polygon feature class
- The output feature class will contain all the features of the original data set
- The attributes of the input data set are preserved.

Notes:

The function goes through a complex process in order to generalize the polygons and preserve the topological relations between them. See this white paper for details about the process.
If you have stand alone polygons only (there are no polygons that share a common boundary) you can use the "Stand alone only" option to make the process faster. DO NOT use this option if there are polygons that share boundary.
The Generalization tolerance should be specified in the units of the spatial reference of the input feature class

Command line syntax

ET_GPGeneralizePolygons <input_dataset> <out_feature_class> <generalize_tolerance> {stand_alone}

Parameters

Expression	Explanation
<input_dataset>	A Polygon feature class or feature layer
<out_feature_class>	A String - the full name of the output feature class (A feature class with the same full name should not exist)
<generalize_tolerance>	A Double representing Generalize tolerance (maximum offset) - the maximum distance that the generalized polygons will differ from the original ones
{stand_alone}	A Boolean. Indicates whether the option for stand-alone polygons to be used. VERY IMPORTANT - Set this parameter to TRUE only on polygon datasets that have only stand-alone polygons (no common boundaries between the polygons).
