Values in grid legend

Hi everybody,

When you create a grid using minimum curvature option, the values results in legend are distinct to values in column used to generate the grid... my question is, what exactly represent these values? thanks.

    Minimum curvature fits a smooth surface to the data points. It will be different from the data value, but should be close enough. Minimum curvature often shows under shoots and overshoots where the values go much lower or much higher than the nearby data values. To ensure that the grid matches the databases values you must use the direct gridding method.

    Hi there, is there some example python code of running Minimum Curvature (stand alone) to make a GRD file? and/or Direct Gridding?
