How to convert WGS84 coordinates to a local CRS?

STEPS

1. Adjust the settings

In a text editor, for instance Notepad or Notepad++, or Excel:

• Open your coordinate list.

UNITS

In the texteditor, 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.

• In the tab Units, your angle setting should be DEC in case of decimal degrees, or DMS in case of degrees-minutes-seconds.

FORMAT

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.

CRS

In Pythagoras, set a Coordinate Reference System.

•  Go 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 change the CS to WGS84.

2. Import the data

Then you can import your data.

•  Go to 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.
