Maya UV layout question

Noth

I have a gradient in my texture. I have many objects that I need placed in UV space so that their place is 3D space corresponds to the gradient properly. How do I do this?

i would project a new gradient and bake them...

I need my UVs to be laid out from bottom to top in relation to their position in the Y axis. Something like 1/10 UV space = 10/100 Y Axis.

I just need it to sort the objects like that for me, the grouping is more important than the values.
