Dear list,
I'm working in Arcview 3.2a, with spatial analyst.
This is what I'm doing: I have a circular buffer zone around a point, and
this buffer zone overlaps another shapefile theme (eg a polygon denoting a
particular land cover class), and I want to work out how much of the area of
the land cover class theme is within the buffer.
What I normally do: I normally use the geoprocessing wizard to create a new
shapefile consisting of the area common to the two themes, then calculate
the area of the new shapefile. This works well.
What is the problem?: I need to do this for 750 separate buffer zones!!!
Is there a quicker/automatic way of carrying out this process? I don't
actually need a separate shapefile for the overlap areas, and a table that
just gives the areas would suffice.
I'll sum any answers I get, thanks to everyone in advance!
If replying directly, please delete the "SPAMREMOVE" section from my

Thanks in advance.
