Comma-separated values (CSV) format coordinates file has to contain station name, latitude, longitude and elevation data. In addition, line name can be provided.

The CSV file must contain header line with column names. Data are recognized according to the column names as follows:

	Note
	Columns in the CSV file can be presented in any order. Unrecognized columns are skipped. Column names are case-sensitive; e.g. data from the column named "Alt" will be imported as stations elevations while column named "alt" will be ignored.

	Note
	UTM coordinates, if present, are preferenced over geographic coordinates.

	Note
	If Instrument height value is imported for each station with geographic data, any value different from the default value must be manually entered into the Loop table for the corresponding station occupation.

	Tip
	Instrument height values used for calculations for the particular station can be easily inspected by expanding the corresponding Station node in the Line table. Similarly, all instrument heights used for a gravity loop can be printed for each station occupation in the Loop report. The Instrument heights checkbox must be selected in the Output and reporting tab of the Project properties window.

The CSV coordinates file can look like this example:

Station,Longitude,Latitude,X,Y,Elevation,Line
BASE,29.58821399,37.6643881,728300,4171800,1270,0
0,29.59081675,37.66527561,728526.9,4171904.84,1280.59,200
100,29.59042609,37.66444295,728494.99,4171811.48,1272.76,200
120,29.59033712,37.66427703,728487.65,4171792.85,1270.48,200

	Note
	Columns X and Y will be ignored in the above example. If you rename columns X nd Y to UTMX and UTMY, geographic coordinates will be ignored and UTM coordinates will be converted to latitude and longitude using project datum settings.

Blue Whale Processing Geophysical Software can import coordinates data from the file prepared from the Stations table in the Magellan GNSS Solutions software provided as an option by the manufacturer with some Ashtech, Thales and Magellan GNSS receivers.

To prepare the file for import, in the Workbook of your adjusted project in the GNSS Solutions software click the Points tab. Select the whole table by a click to the upper-left (blank) cell of the table. Right-click the table and select the "Copy" option. Open a blank text file in Notepad and paste the selected data into it. Save the Notepad txt file at the suitable location in your computer.

The prepared txt file should look like this:

Name	Description	Long	Lat	Ellips height	Status	Constraints	Surv_Horz_Conf	Surv_Height_Conf	Type	Warning
BASE		15° 17' 47.09059"E	50° 08' 09.01157"N	496.662	Adjusted	Horizontal & Vertical Fixed (3D)	0.000	0.000	Control Point	No
2001	 	15° 13' 48.81734"E	50° 07' 42.76530"N	474.735	Adjusted	No constraints	0.022	0.015	Logged Point	No
2002	 	15° 13' 26.49182"E	50° 09' 36.53375"N	413.180	Adjusted	No constraints	0.026	0.018	Logged Point	No
2003	 	15° 16' 21.78458"E	50° 12' 53.36935"N	433.376	Adjusted	No constraints	0.031	0.019	Logged Point	No

	Note
	Only stations with status "Adjusted" will be imported. Please adjust your network solution before making the import file.

	Important
	GNSS Solutions import txt file should contain stations from a single line only. In case your GNSS Solutions project contains stations from more than one line, prepare separate file for each line containing stations from the corresponding line only.
