Opening an Existing Data File - Tutorial

To look at an example of an XYZ data file, you can open any sample data file in a worksheet window:

  1. Click the File | Open command, click the button on the quick access toolbar, or press CTRL+O on the keyboard to open the Open dialog.

  2. If you are not in the Samples folder, browse to it. By default, the Samples folder is located in C:\Program Files\Golden Software\Surfer 16. In the list of files, click TutorWS.dat.

  3. Click Open to display the file in the worksheet window.


Notice that the X coordinate (Easting) is in column A, the Y coordinate (Northing) is in column B, and the Z value (Elevation) is in column C. Although it is not required, row 1 contains header text, which is helpful in identifying the type of data in the column. When a header row exists, the information in the header row is used in the Properties window when selecting worksheet columns.


When a data file is displayed, the name of the file is shown in the title bar and in the worksheet tab. In this file, row 1  contains descriptive information about each column of data.
