Difficulty with Interpolation / FunctionInterpolation

I am trying to calculate the volume under a given topography. The data I have is topographic lines with {x,y,z} coordinates that are not on any grid pattern. I am trying to utilize Interpolation or FunctionInterpolation to create an InterpolatingFunction for use in NIntegration. It seems that since the data points are not well arranged I get the following message: Interpolation::"indim" : " StyleBox[\"\"\", \"MT\"] The coordinates do not lie on a structured tensor \ product grid " Does anyone have suggestion as to how I could sort the data to get the Interpolation to work?
