When selecting input locations from a text file (e.g. CSV file), the Input Locations dialog box will look like this:
Ultra MileCharter does not currently support geocoding, so all locations have to be specified using decimal longitude, latitude coordinates.
The source and destination locations are typically stored in separate text files, but using the same separator. Select the separator using the Field Separator dropdown. The above example uses the TAB character, but true CSV ('comma separator value') files will use the comma (',') character. You can also select the semicolon (';') character.
Select the input text files using the '...' buttons to the right of the boxes for CSV File with the Source Locations and CSV File with the Destination Locations.
For each input file, select the data columns in the boxes on the right. Three columns have to be selected: Longitude, Latitude, and Name. The name refers to how this location will be labeled in the output chart. As well as a string name, you can use a numeric identifier.
Often, a text/CSV file will use the first row for column headers. If this is the case, set the respective First Row Contains Column Headers check box.
The box in the lower left specifies what has been set, and what still needs to be set.
Press OK when all of the text file settings have been specified, to return back to the main dialog box.
