Hi, I have an interesting problem. I have two separate polygon layers in ArcMap/ArcPro One layer, B, is made up of smaller polygons and contained within another layer, A. B contains an EXT attribute, which can be different, so for example layer B has three polygons completely contained by layer A, and these three polygons have different EXT attributes, say 1, 4 and 7. I would like to merge these EXT attributes into layer A, so that layer A has a field called EXT, containing 1,4,7 from the layer B.
There is nothing unique between these two layers so I cannot do a relate or table join, I can only do a join based on spatial location, or try using dissolve, merge geoprocessing tools. I've tried all of these and haven't gotten the result I want. Is this actually possible? I don't want to sum, or average or range these EXT values. Iwant to preserve them. I want them all in a new EXT field for A, preferably separated by a space or comma.
