I want to find those polygons which have a partial intersect with the same parcel_id and coverage_id and union the intersected ones as One polygon. For example if I have 6 polygons with the same parcel_id and coverage_id and two of them have 5% overlap and another two touch their boarder, I expect to have four polygons at the end. how should I make it?<br><br>I appreciate your advice in advance<br>Many<br><div><br></div></div></body></html>
