Coordinate System: This is the coordinate system associated with the data in the input file. Select or define the coordinate system by clicking . By default this is set to the coordinate system in the project properties dialog if you have a project selected. If you are not currently in a project the coordinate system will be blank.

Input File: This is the columnar ASCII file that you will be performing conversions on. You can click  and select the file, or type the name into the dialog.

Define Columns: Click on this button to define the columns from the file for conversion. You need to define either the X and Y columns or the Latitude and Longitude columns. If you define X and Y as well as Latitude and Longitude both sets of columns will be converted. For help with this step refer to the defining columns help document. Note: You can specify columns other than X, Y, Latitude and Longitude. Any extra columns specified will be written to the output file unmodified.

Coordinate System:This is the coordinate system that the data will be converted to before being written to the output file. Select or define the coordinate system by clicking on . By default this is set to the coordinate system in the project properties dialog if you have a project selected. If you are not currently in a project the coordinate system will be blank. Note: Set the destination coordinate system to be the same as the source coordinate system if you are just creating x and y locations from latitude and longitude values, or if you are just creating latitude and longitude values from x and y locations.

Output File: This is the columnar ASCII file that will contain the converted data after performing coordinate conversions on the Input File. You can click and select the file, or type the name into the dialog. Note: If the input file is fixed width, the output file will be written as a tab separated columnar file. Also note that any comments that may appear in the input file will be lost.

Specify addition information about how to format the output file.

Coordinate System:This is the destination coordinate system when converting between two coordinate systems. If you only want to convert latitude and longitude values to x and y values you do not need to define this coordinate system. Select or define the coordinate system by clicking . By default this is set to the coordinate system in the project properties dialog if you have a project select. If you are not currently in a project the coordinate system will be blank.

Replace existing columns in the file: Checking this option will allow you to convert the X, Y, Latitude and Longitude columns in place within the file. The converted values will appear in the same columnar location in the output file.

Add latitude and longitude columns to the output file: Check this option to add an extra column of latitude and longitude values to the output file. The original latitude and longitude values will appear in the output file along with the converted values. Note: This option is not available when Replace existing columns in the file has been selected.

Add x and y columns to the output file: Check this option to add an extra column of x and y values to the output file. The original x and y values will appear in the output file along with the converted values. Note: This option is not available when Replace existing columns in the file has been selected.

Latitude/Longitude Format: Specify how you would like the latitude and longitude values to appear in the output file. Note: You can convert a file from degrees minutes seconds to decimal degrees by changing this option.

• Decimal degrees: Output latitude and longitude values in decimal degrees. (e.g. -54.3923491)
  

• Degrees minutes seconds: Output latitude and longitude values as degrees, minutes and seconds (e.g. 54 23 32.4567235 W)
  

Convert: Convert the input file and write the result to the output file.
