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.
- Thickness Name
-
(Displayed only after you click the Thickness column name.) Enter a name for the thickness.
- User Defined Column Name
-
(Displayed only after you click the User Defined column name.) Enter a heading name for the user-defined column.
- Data Type
-
(Displayed only after you click the User Defined column name.) Select the type of data the column contains:
- Double: Contains a double precision floating point value. Use Double for numbers that contain decimal points, including elevations, northings, eastings, grid northings, grid eastings, latitudes, and longitudes.
- Long: Contains a long integer value. Use Long for point numbers.
- String: Contains an alphanumeric value. Use String for point descriptions and point names.
