Online Conversions - advanced

The coordinate converter has been upgraded to account for the tectonic movement of New Zealand. This means that converting coordinates from global systems such as WGS84 and ITRF realisations to New Zealand coordinate systems requires a transformation date, and that the resulting coordinates are different to those from the previous less accurate version of the coordinate converter.

Convert between pre-selected geodetic datums and projections using default input and output parameters.

Use the basic online conversion to choose between pre-selected datums and projections using default input and output parameters.

Use the vertical datum conversion to convert between New Zealand vertical datums - see instructions for carrying out height conversions for more information.



Input coordinate system

   
   
Coordinate order
    North/East
    East/North

Choose whether input coordinates have northing (latitude) or easting (longitude) coordinates first.
   
Coordinate format
    Degrees/minutes/seconds
    Degrees/minutes
    Decimal degrees

Choose whether latitudes and longitudes are entered as degrees, minutes, and seconds (eg 41 30 25.3 S) degrees and minutes (eg 41 30.42 S) or decimal degrees (eg -41.50703). (This is ignored for projection coordinate systems)
   
Height coordinate system

Select the height coordinate to enter - none, ellipsoidal, or an orthometric system. Note: Ellipsoidal heights are in terms of the ellipsoid of the input coordinate system.

Output coordinate system

   
   
Coordinate order
    North/east
    East/north

Choose whether output coordinates have northing (latitude) or easting (longitude) coordinates first.
   
Coordinate format
    Degrees/minutes/seconds
    Degrees/minutes
    Decimal degrees

Choose whether latitudes and longitudes are output as degrees, minutes, and seconds (eg 41 30 25.3 S), degrees and minutes (eg 41 30.42 S) or decimal degrees (eg -41.50703) (This is ignored for projection coordinate systems)
   
Height coordinate system

Select the height coordinate to calculate - none, ellipsoidal, an orthometric height coordinate, or geoid heights.
Note: The geoid height option calculates the height of the geoid at the point - not the height of the point above the geoid. To get the height of the point above the geoid you must pick an orthometric height system (eg New Zealand Vertical Datum 2009). Ellipsoidal and geoid heights are in terms of the ellipsoid of the output coordinate system.

Conversion options

    Conversion date
Specifies the date at which the conversion applies. Many conversions, for example from NZGD2000 to ITRF2008, depend upon the date. The date can be entered either as as decimal year (eg 2000, 2013.5), a day/month/year format (22 8 2012, 5 Jan 1995) or the word "now" for the current date.
    Input format
         Delimiter
Coordinates are entered one per line. Specify the delimiter character that will be used between coordinate elements on each line (the default is a space character).
   
Output format
    Formatted
    Unformatted
         Delimiter

Choose formatted to display the output coordinates as a table, or unformatted to return the coordinates in a simple form suitable for copying to spreadsheets or other documents. For unformatted text specify the delimiter character to use to separate the coordinate elements.
   
Output precision (metres)
    1.0
    0.1
    0.01
    0.001
    0.0001

Select the approximate precision used for the output coordinates. Note that this affects only the number of digits displayed, not the actual accuracy of the coordinates.
   
Points have names/codes
    No
    Yes

Select this option to enter a point name (or code) for each coordinate
   
Show input coordinates in the output
    No
    Yes

If this option is selected the input coordinates will be copied in the output.
