I think this might be an issue of version number.
I can say unequivocally that this USED to happen all the time when dealing
with irregularly shaped polygons (as we do with geologic maps.) In point
of fact, we had to write routines to move such centroids back in to the
polygon (in order to update the point with attributes of the polygon) so we
could properly clean and build data sets and still retain the
attributes. If I am correct, it used to be that the centroid was the
center of the maximum bounding rectangle for the polygon? Thus with the
oddly shaped (call them out of balance if you like ) polygons the centroid
was outside the polygons. However, at some point, and I cannot recall
when, this changed, such that if you have such an oddly shaped polygon the
centroid is now inside of it. Is this an issue of version number???
