easiest would be if you just used a circular buffer around each
point and then calculated back from the circle area you would want the
buffer to contain using the a mathematical circle area calc. Such as 1km² =

the circular buffer radius would give you potential cut shape. Now the
problem is that raster (not really) can be cut by circular shapes (well it works
kind of visually at least), but a raster is rectangular
feature, however can contain NULL values for values outside a cut
line.</SPAN></FONT></FONT></FONT></SPAN></DIV>
