I want to check whether the Centroid of Polygon from A intersect a 10 feet buffer of centroid of polygon from B.<BR /><BR /><BR />I used ItopologicalOperator.Buffer to Create the buffer from B. I believe the centroid of the Polygon from A can be obtained by using the below method<BR /><BR /><PRE class="plain" name="code">set pFeatClassA = pmap.layer(0) Dim pFeatureA as iFeature Set pFeatureA = pFeatClassA.GetFeature(123) Dim pPolygon as Ipolygon Set pPolygon = pFeatureA.Shape Dim pArea as iArea Set pArea = pPolygon Dim centroidPt as iPoint Set centroidPt = pArea.Centroid</PRE><BR /><BR />But which method can be used to find whether these geometries intersect since there are no physical features corresponding to the centroid and the buffer polygon? IspatialFilter is the only option that i know of. But it seems it can be used only&nbsp; from a FeatureClass or Selection set. Can someone help me on this? <BR /><BR />Note: I do not want to create additional feature classes for this. It would have been a simple solution then.<BR />Thanks in advance..<BR /></SPAN></BODY></HTML> Tue, 07 Feb 2012 09:14:33 GMT https://community.esri.com/t5/arcobjects-sdk-questions/ispatialfilter-without-featureclass/m-p/407973#M10916 VinayanMP 2012-02-07T09:14:33Z Re: ISpatialFilter without FeatureClass https://community.esri.com/t5/arcobjects-sdk-questions/ispatialfilter-without-featureclass/m-p/407974#M10917 <HTML><HEAD></HEAD><BODY><SPAN>you could use IRelationalOperator to determine the spatial relationship.</SPAN></BODY></HTML> Tue, 07 Feb 2012 13:33:31 GMT https://community.esri.com/t5/arcobjects-sdk-questions/ispatialfilter-without-featureclass/m-p/407974#M10917 sapnas 2012-02-07T13:33:31Z Re: ISpatialFilter without FeatureClass https://community.esri.com/t5/arcobjects-sdk-questions/ispatialfilter-without-featureclass/m-p/407975#M10918 <HTML><HEAD></HEAD><BODY><SPAN>great!!</SPAN><BR /><SPAN>Thanks for the reply..</SPAN></BODY></HTML> Tue, 07 Feb 2012 14:28:01 GMT https://community.esri.com/t5/arcobjects-sdk-questions/ispatialfilter-without-featureclass/m-p/407975#M10918 VinayanMP 2012-02-07T14:28:01Z
