Helmert 7 parameter transforma

將緯度經度位置從一個橢球體轉換為另一個橢球體

With this app you can easily calculate with the 7 parameter transformation of Helmert.

The Helmert formulas are use to change the latitude and longitude of a position on one ellipsoid to the same position on some other ellipsoid.

The seven parameters that are used in the Helmert formulas are:

distance on the x-axis

-distance on the y-axis

-distance on the z-axis

-rotation around the x-axis

-rotation around the y-axis

-rotation around the z-axis

-scale

The Helmert formula is often used in GPS land surveying. And now with this app you can easily calculate any position with the Helmert formula.

You only have to fill in the correct parameters. And of course the latitude and longitude of the position that you want to transform.
