And thanks for this. I will have some time to work thought this tomorrow, and will report back here.

Nadya, I appreciate this comment. At this point, a simplified model is a simpler model. Just curious, and I hope you don't mind my asking, where are you studying geomatics?

The buffers represent plums of pollution (really, exposure potential from specific substances) from the emissions sources such that the exposure potential is cumulative from all emissions. As such, I am looking to add all of the overlaps so that each buffer can be separated into as many discrete polygons as their are overlaps. Nadya, I really appreciate your help and thinking on this!

I have figured out how to assign a value to the buffer - via the properties > style function of the layer. Now, to aggregate those values where they overlap! Thanks everyone one for you thoughts so far.

Yes, I would like to aggregate values as a sum of the overlap areas - but only of the overlap areas, not of the whole buffer.I suppose I will have to split the buffers and aggregate the bits that overlap. I am uncertain how to do this.

comment How to create a 500m Regular Grid for KML input area?
I got it to work, but there seems to be some sort of conflict between the plug-ins. As an experiment when I first loaded QGIS, I loaded all of the plugins available from the Plugins > Manage Plugins menu. From that time I could not get the Vector > Research Tools to work. This time I unloaded all of the plugins, loaded only the fTools, and voila, the grid analysis worked.
