Note: For each Added Point File, users need to set up how the file is to be interpreted. To delete a points file, select the File Name in the row and press the Delete button to clear the name and path | Field 1 to Field 7 | Between 3 and 7 Fields may be required depending on the detail of information provided in the Points File. Each 'Field' correlates with the order that point data is expressed in the Point File.
