Point File Formats - Select Column Name Dialog Box

Use this dialog box to specify a column to be included in a point file format.

After you chose a column name, the dialog box displays additional edit boxes that are consistent with the type of data the column contains.

Column Name

Specifies the name of the column to be included in the point file format. For more information, see About Point File Formats.

• <unused>: Designates a column in the point data file that is empty or that contains data you do not want imported or exported.
• Easting
• Northing
• Point Elevation

Note: The elevation value in a point data file can be adjusted during import or export. For more information, see To Adjust Point Elevation During Import and Transfer.

• Point Number
• Name
• Raw Description
• Full Description

Note: You cannot import the full description; you can only export it.

• Grid Northing
• Grid Easting
• Longitude
• Degrees-Longitude
• Minutes-Longitude
• Seconds-Longitude
• Hemisphere-Longitude
• DECDEG Longitude
• DASHED Longitude

Note: A DASHED longitude value is expressed with dashes, such as 73-13-12.67.

• Latitude
• Degrees-Latitude
• Minutes-Latitude
• Seconds-Latitude
• Hemisphere-Latitude
• DECDEG Latitude
• DASHED Latitude

Note: A DASHED latitude value is expressed with dashes, such as 73-13-12.67.

• Thickness: For more information, see To Adjust Point Elevation During Import and Transfer.
• User Defined: Specifies a custom column format. Create as many custom columns as you need. Specify a name for the column, a data type, and an invalid indicator value. You should use this option when you need to copy columns from the source file to the destination file during a Transfer Points command.
• Z+: Specifies a positive elevation adjustment.
• Z-: Specifies a negative elevation adjustment.
• Convergence: Contains calculated convergence angles during point export. For more information, see About Calculating Convergence Angles During Export.
• Scale Factor: Contains calculated scale factors for export. For more information, see About Calculating Scale Factors During Export.
• <user-defined>: Displays the name of a user-defined property. If you are importing point data from and ASCII file that contains user defined columns, you must create a user defined classification for each column. For more information, see To Import Point Data From an ASCII File Containing User Defined Columns.

Invalid Indicator

(Displayed only after you click a column name.) Specifies a value that causes this column to be ignored when detected in the point data file. Enter a value, for example, 999999.

Precision

(Displayed only after you click a column name that requires a decimal value.) Enter the number of decimal precision places for the column, up to 12.

• Long: Contains a long integer value. Use Long for point numbers.
• String: Contains an alphanumeric value. Use String for point descriptions and point names.
