If you for example have measured objects in Metria CityModeler and these are shown translated in Google Earth, you can correct this by entering the Google Earth coordinates for a specific point in the object translation dialog.

Imediatelly after clicking adjust model, the object coordinate adjustment dialog will be shown with the coordinate fields set to "Undefined".

Click on a point in the primary image for which you have known object coordinates. If the point in the secondary image is not on the corresponding object, you should drag the Z slider until the points in the primary and secondary image correspond to the same object. The object coordinates are displayed in the dialog. You can show the coordinates in either the UTM or WGS-84 system.

Enter the known coordinates in the Translate to coordinate box and click Apply.

A confirmation message box is displayed. The files containing the original sensor models are backed up, so that they can be restored manually. A full restoration of both sensor model and mesaured objects can be made by selecting undo while the measuring mode is open. Having closed the object adjustment dialog, you can still undo the adjustment by clicking object adjust in the action radio box. When an object adjustment is undone, the to and from coordinates are reset to the values they had when the adjustment was applied. Thus, to redo the adjustment, just click Apply again.
If you have made an object adjustment and want to make a new object adjustment, you have to take these steps:
A copy of the original transformation file will be saved. The copy will have the name filenameN.ext, where N is 1 if it is the first backup, 2 if its the second etc, and ext is txt or rpb depending on satellite. Note that if you adjust the object system, close Metria CityModeler, and restore the original sensor files as described in the confirmation message box, the objects in the Shape file will be displaced. This is because the objects in the Shape file will still be translated with respect to the original sensor model while the sensor model used to transform the objects to the images will be in the original untranslated system.
