This article explains how to select the correct vertical coordinate reference system, geoid, or geoid height in Pix4Dmatic.
Pix4Dmatic supports global geoids (EGM84, EGM96, and EGM2008) and local geoids, for example, GEOID12B in the US and OSGM15 in the UK.
For local geoids that are not included in the Pix4Dmatic database, it is possible to specify the Geoid height value to convert between ellipsoidal and orthometric heights.

Selecting the vertical coordinate reference system
After selecting the Horizontal coordinate reference system, the list of Vertical coordinate reference systems is available.
Only Vertical coordinate reference systems within the area of use of the Horizontal coordinate reference system are listed.
Selecting the geoid
Several geoid models are available in the Pix4Dmatic database. The full list is available in the List of supported geoids section.
The list of available geoids depends on the selected vertical coordinate reference frame.
Selecting the geoid height
At the moment, the import of local geoids is not possible. As a workaround, it is possible to specify the Geoid height value, which represents the height between the base ellipsoid of the horizontal coordinate reference system and the desired geoid.
The Geoid height value is used to convert the image geolocation (WGS 84 ellipsoid or EGM96 geoid) into the desired project coordinate system.
