| Subject: | GISList: add poly theme values to point theme |

Hello again,
I have a point theme (poly centroids for districts) and a poly theme
(buffer around a line). How can I attach the value of the poly theme
(i.e. distance from the railroad) to the point theme (centroid of the
district)? Or can I somehow attach the value of the buffer at the
district polygon's centroid directly (ie without generating the point
theme first)? Intersecting the district poly theme with the buffer
poly theme does not do what I want (one district may contain several
buffer distances or may be completely contained within one buffer).
Any ideas?
Thanks
Rick Gray
