I can't seem to find an answer from the documentation. When joining points to polygons to choose points closest to each polygon, the spatial join tool gives this message that it's choosing points closest to the boundary of polygons. Should i take this to mean that the tool is calculating distance between points to the closest edge of the polygon, not the polygon centroid? If so, it accomplishes the same task as the near tool? I thought spatial join is an overlay type of function, not proximity-based, and hence distance computing uses centroid of each polygon. Any clarification is very much appreciated!
