CleanPolygonWizard

Ensures topological correctness of a polygon feature data set.

Inputs:

Outputs:

New topologically correct Polygon feature class (no overlaps present)
- Redundant data (overlaps and gaps smaller than the fuzzy tolerance) will be eliminated
- The overlaps greater than the fuzzy tolerance are converted into new polygons.
- Every new polygon carries the attributes of one of the source overlapping polygons
- The attributes of the input data set are preserved
Optional Point feature class that identifies the overlaps in the input data set. Several fields are added to the point attribute table enabling the user to identify the overlapping polygons in this location :
- [Num_Over] - the number of overlapping polygons in this location.
- [Old_FID1], [Old_FID2] ...[Old_FIDn] carrying the original IDs of the overlapping polygons

Notes :

The default Fuzzy tolerance is calculated from the extents of the input layer using the formulae (W + H) / 2000000 where W and H are the with and height of the extent envelope.
Larger values of the Fuzzy tolerance may be used to clean some bigger Gaps and Slivers, but it might lead to unwanted approximation of the input shapes. The better option is to use Fuzzy tolerance close to the default and then clean the remaining Gaps and Slivers with the "Clean Gaps Wizard" and 'Eliminate Wizard"
A Fuzzy tolerance of 0 may be used if the original shapes have to be preserved exactly the same. In this case all the overlaps will be converted into new polygons.

Command line syntax

ET_GPCleanPolygon <input_dataset> <out_feature class> <fuzzy_tolerance>{overlaps_feature_class}

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)
{fuzzy_tolerance}	A Double setting the Fuzzy tolerance (in the units of the input dataset) to be used if the {clean_polylines} is True. If {clean_polylines}is False this parameter is ignored
{overlaps_feature_class}	A String - the full name of the output point feature class that identifies the overlaps in the input feature class. (A feature class with the same full name should not exist)

Scripting syntax

ET_GPCleanPolygon (input_dataset, out_feature class, fuzzy_tolerance,overlaps_feature_class)
