In this section you can transform the elevations (H) of the points from one system to another using 1D transformation.

Transformation method

The supported transformation methods are:
• 3D plane rotation (5 parameters);
• elevation transformation (1 parameter).

For information on the manner of selecting the transformation method read the page with Recommendations.

Parameters

Parameters can be typed, loaded from a file or copied from another parameters box. The description of the buttons and of the contextual menu of the parameters group box can be found at The contextual menu of the parameters group box.

The file with parameters must contain 6 lines for the first transformation method with the following information:
1. text with the description of the transformation parameters;
2. the translation on the east (Te);
3. the translation on the north (Tn);
4. the elevation translation (Tz);
5. rotation on x (east) Re in sexagesimal seconds;
6. rotation on y (north) Rn in sexagesimal seconds.

For the second method of transformation the file with the parameters must contain 2 lines with the following information:
1. text with the description of the transformation parameters;
2. the translation on the elevation (Tz).

The reversal of parameters can be made ​​only for the method "elevation transformation (1 parameter)". For the method "3D plane rotation (5 parameters)" you can apply the reverse transformation using forward transformation parameters.

In the Parameters calculation section from the main program you can calculate and save these parameters to a file.

Coordinate tables

In the two tables the coordinates can be typed, loaded from a file or copied from another table. Coordinates from tables can be saved to file or can be exported to Microsoft Word or Microsoft Excel. The description of the buttons and of the contextual menu of the tables can be found at The commands of the coordinate tables.

A point from table is considered valid only if its name (point number) and (N,E,H) coordinates are introduced.

Button Transform →

By using this button the points from the left table are transformed according to the selected transformation method and then written in the right table.

Button ← Transform

By using this button the points from the right table are transformed according to the selected transformation method using the reverse transformation and then written in the left table.

The button is active only for transformations that support reverse calculation using forward transformation parameters.

Information about the way in which the transformations are made can be found at Used Formulas.
