Hi,
Now I have a question related to the same research project mentioned on
the previous message. We have performed a polygon overlay (graphic),
using the very same Add On shared by Peter Van Demark several years ago
(1996). So far I have not found a way to perform a graphic polygon
overlay on any Maptitude version without that beautiful program! The
thing that is needed is:
Once overlaid a bunch of census tracts on top of bigger areas, we would
need to "transfer" all the population values of the census tracts to the
new areas produced by the intersection, but not only the population
which is proportionally calculated by the intersected areas but the
whole amount of it withing the census tract full boundaries. When the
census tracts are totally contained on the bigger areas that is what
happens, the problem starts when a part or parts of the census tracts
are cut by the other area layer. Is there a way to do that with
Maptitude user interface or do we have to create a GisDK program to
acquire the desired results?
Thanks in advance for any suggestion or tip you might have to help. Cheers,
Reinaldo
