The Overlay operation checks polygons that fall between the two values to
see how wide they are. If they are very narrow, they are merged with a
neighboring polygon.
NOTE If the resulting polygons are not as desired, try adjusting the tolerance
values and repeating the Overlay operation.
Minimum
Specify a value in the current units. If a polygon is smaller than this value,
it merges with a neighboring polygon.
Maximum
Specify a value in the current units. If a polygon is larger than this value,
it becomes its own feature.
Suggest
Click to see recommendations for the Sliver Minimum and Sliver Maximum
values (if they are not already displayed).
To see recommended values, click Suggest. The default suggested values for
sliver tolerances are 1/10 of the smallest input area for the Maximum and
1/100 of the smallest input area for the Minimum. However, the sliver
tolerance values will round down to the next power of 10. So, if the smallest
polygon has an area of 50, the expected sliver tolerances should be 1 and
0.1 respectively, and not 0.5 and 5.
Units
Specify the units to use for the sliver Minimum and Maximum settings.
The available units depend on the Source coordinate system.
Don’t Remove Slivers
Select this check box to have the Overlay operation ignore sliver polygons.
Ordinate Tolerance
Specify how far apart two nodes or vertices of a line or polygon must be to be
treated as separate points.
Length
Enter a distance in the current units. Any two points that are closer together
than this value are treated as a single point in the output layer.
Units
Specify the units to use for the Ordinate Tolerance Lengthsetting. The
available units depend on the Source coordinate system.
