Coordinate Calculator

The coordinate calculator is used to convert Geodetic coordinates to Cartesian coordinates and vice versa. You can also use it to convert ellipsoid heights to orthometric heights if you have defined a geoid.

Define Coordinate Systems

Press the Select Coordinate Systems button to select the coordinate system and geoid you want to use.

In the following example the user chose to convert between UTM NAD83 Zone 11 to Lat and Long WGS 84. Also at the same time the elevation is being converted from an ellipsoid height to an orthometric height using the Canadian HT2.0 geoid.

Convert Coordinate

Once you've defined the coordinate systems you want to convert between you can then enter some numbers.

Press the Convert button to make the computation.

Information

Press the information button to see details about the coordinate system such as grid scale, and convergence angle.
