Minimum curvature gridding producing negative output.

Post by tekarmah »

I have been trying to grid my radiometric dataset in Geosoft, using the minimum curvature option. The grid output includes negative values but my input data are all positive. Why is it that the grid output includes negative values?

Not familiar with Geosoft, but I would think that within the guts of the gridding algorithm there is some curve fitting such as splines, and it can overshoot between the data points.
