Subject area and volume for complex shapes 
Author Chris Johnson

Message Hello,

I want to calculate area and volumes for a surface with a polygon area.

The 3d analyst > surface analysis > area and volume tool will do this for a raster, but will not limit the calcs to a polygon area.

Alternatively, i could clip the raster to the polygon and calculate the area and volume.

The attached jpg shows the polygon (shown in the green) i wish to clip my raster dem (shown in blue colourmap) dataset to.

I'd appreciate any advice on this problem.

Thanks,
Chris
