The input polygon features to be simplified.
Output Feature Class
The simplified output polygon feature class. It contains all fields present in the input feature class. The output polygon feature class is topologically correct. The tool does not introduce topology errors, but topological errors in the input data are flagged in the output polygon feature class.
The output feature class includes two additional fields, InPoly_FID and SimPgnFlag, that contain the input feature IDs and the input topological errors or discrepancies, respectively.
SimPgnFlag attribute values are as follows:
Specifies the polygon simplification algorithm.
The tolerance determines the degree of simplification. You can choose a preferred unit; otherwise, units of the input will be used. The MinSimpTol and MaxSimpTol fields are added to the output to store the tolerance that was used when processing occurred.
The minimum area for a polygon to be retained. The default value is zero, that is, to keep all polygons. You can choose a preferred unit for the specified value; otherwise, units of the input will be used.
Handling Topological Errors
This is a legacy parameter that is no longer used. It was formerly used to specify how topological errors possibly introduced during processing were handled. This parameter is still included in the tool's syntax for compatibility in scripts and model but is hidden from the tool's dialog box.
Keep collapsed points
Specifies whether an output point feature class will be created to store the centers of polygons that are removed because they are smaller than the Minimum area parameter value. The point output is derived; it will use the same name and location as the Output feature class parameter but with a _Pnt suffix.
Input Barrier Layers
The inputs containing features to act as barriers for simplification. Resulting simplified polygons will not touch or cross barrier features. For example, when simplifying forested areas, the resulting simplified forest polygons will not cross road features defined as barriers.
|Polygons Collapsed To Zero Area|
When the Keep collapsed points parameter (collapsed_point_option in Python) is used, an output point feature class is created to store points that represent polygons that are removed because they are smaller than the minimum area.
