More Options - Input Data Restriction

The input data restriction option enables you to restrict the input horizon data to positive or negative values, and set minimum and/or maximum values. For example, you might want to restrict points that are outside the range you want to grid. A typical reason for doing this is when you have bad data that you do not want to fix. You can set the grid to restrict the bad data, making the grid work.

You have the following choices:

No Restriction – Use all input data in the gridding calculation.
No Negative Data Allowed – No negative data is used in the gridding calculation.
No Positive Data Allowed – No positive data is used in the gridding calculation.
Set a maximum limit – Sets a maximum value for the input data used in the gridding calculation. Specify the maximum value in the text box to the right.
Set a minimum limit – Sets a minimum value for the input data used in the gridding calculation. Specify the minimum value in the text box to the right.
Set both max and min limits – Sets both a minimum and a maximum value for the input data used in the gridding calculation. Specify the minimum and maximum values in the text boxes to the right.

For each restriction, you can choose an action on those data that exceed the specified limit.

Do not use those data – Data outside the limits you set will be ignored by the grid calculation.
Replace the value with the limit – Replace any value that exceeds the limit with the value you set for the limit.
