Import Surfer Grid File Dialog Box

Scroll Prev Top Next More

The Import Surfer Grid File dialog box is used to import either binary or ASCII grid files generated by SURFER ® (https://www.goldensoftware.com/). The data in the file is imported into ModelMuse as a single object on the top view of the model. Each data point in the grid file will be represented by a separate vertex in the imported object. The dialog box is displayed by selecting File|Import|Surfer Grid File...

At the top of the dialog box displaying the extent of the data in the grid file. This is for informational purposes only and does not control how the data are imported. The imported data are used to set the values of a data set. The data set can be either a new or an existing one; however, the orientation of the data set must be "2-D Top.” The user can determine whether the object that is imported will set the values of intersected cells or set values by interpolation. If the data are being used with a new data set, the user can choose an interpolation method for the new data set. (See Interpolation Methods.)  The name of the imported object will be based on the name of the file from which the objects are imported. The Select Objects by Name dialog box can be used to select all this object at a later time.

The points from each file that is imported will set the values of either a new data set or an existing 2D top data set. The points can set values of either the intersected cells or elements or be interpolated to all the cells or elements. The user can choose to import all the points in the file or to filter the points. If the points are more closely spaced than the grid spacing, filtering is recommended. When filtering the points, the user can choose to import the lowest value in a cell or element, the highest value in a cell or element, the mean average value in a cell or element, or the value of the point closest to the center of a cell or element.

The user can elect to convert the length units of the X and Y coordinates from any of the commonly used length units to other units. By default, this option is not selected. This option is only useful when the only difference in the projection used in the Shapefile is consistent with the data in ModelMuse except for the length units. Converting the length unit does not result in the conversion of any imported value.
