I have a tricky SQL someone might be able to help me with (at least, it's
tricky for me).
I have two tables of polygons, one is land use, the other are management
units. I need a breakdown of land use within each management unit. I need to
be able to say for example, "management unit Type A comprises 10% cropping,
and 90% grazing land use."
There was a discussion not long ago about the use of the AreaOverlap
function, but I can't seem to make it work for me. It would be nice if I
could do this by calculating proportion overlap, rather than having to split
the land use polygons. The two files are very big and complex.
Any ideas?
