Spatial Join

This geoprocess transfer attributes from a source layer to a target layer (very similar to an alphanumerical join). The difference with a traditional join is that the transfer criteria is not the value of one (or many) given attributes. The criteria to transfer attribute values is spatial: intersection or proximity.

If users select intersection like transfer criteria, each feature of the target layer could intersect many features of the source layer (a 1-N spatial relationship).
If users select proximity (nearest neighbour) we have a 1-N spatial relationship.
