Is there a script to calculate the surface area of a NURBS surface?

How about for a flat, 2D NURBS surface?

I'm using MoI to map the blocks of trees in an orchard, from Google Earth Maps, so 2D surface area would be helpful.

Square footage area would be converted to Acres, using a baseline distance, perhaps in Excel, for crop insurance purposes. The crop insurance guys
used to run quad bikes with GPS around to make the maps, but quit doing it.

I think I can export the MoI trace of the map to another application, to measure the area, or just measure rectangles and triangles, so it is a very low priority feature.

Thank you,
Brian
