• Open your coordinate list in a text editor, for instance Notepad or Notepad++, or Excel.
  • Check the units of the angle: is it decimal degrees, or degrees-minutes-seconds?
  • In Pythagoras, set the angle to the same unit:
  • Go to Settings > Preferences.



  • Your angle setting should be DEC in case of decimal degrees, or DMS in case of degrees-minutes-seconds.



  • It is required that the format of the coordinate list file is POINTNUMBER - LATITUDE - LONGITUDE. A Z-value is optional. So, if necessary, edit your file in Excel to add a POINTNUMBER column.



  • In Pythagoras, set a Coordinate Reference System by going to Settings > Document Settings > Coordinate Reference System.



  • Set a CRS system (CRS = Coordinate Reference System, like UTM). It doesn't matter which one, but it’s logical you choose one appropriate for the country or area the coordinates are located in.



  • In the control panel, set "WGS84" active.



  • Then you can import your data using File > Import > Coordinate List.



  • Select the first option if the file does not contain Z-values, select the second option if the file does contain Z-values.



  • Select the coordinate list file.
  • The points will now be imported in Pythagoras, while their coordinates are converted to the CRS.
