Dear All , 

 

 

I am looking for a way to identify almost identical polygon from two different feature classes . Is there is a way to find similarity by tolerance. Thanks in advance

 

Possibly the Matcher ?
Hi,

 

 

the SpatialRelator offers some tests -> EQUALS.

 

 

Maybe that helps you,

 

best regards,

 

Stefan
If they are "almost" identical then matcher and spatial equality are not realy usefull. You can thin the features by those who are not matches...for sure.

 

 

How i would go about this is extract nodes and/or boundary and also calculate surafce.

 

Compare these sets, you then can indeed set tolerances.

 

Tolerances can be surfacetolerance, angular difference of boundarysections or coordinate deviation of nodes.

 

U could use statisctics calculation and principles of normal distribution to do this comparison.

 

 

Thanks all, I think Gio is right since features are not identical, I have to try his way.
