hi Sagar,<br>
<br>
the reason why asum and asumg give the same answer is that world
coordinates (e.g., lat/lon) bounds were on the grid boundary. I
wrote asumg to ignore if a the world coordinate bound was in the
middle of a grid box. If it was, then asum would only add half the
value of that grid box to the sum whereas asumg would add the whole
value.<br>
