Hi,
I have a georeferenced image with resolution 0.5m. This image was added
to Google Earth Pro and there was created several paths and marks. This
is screenshot from Google Earth with a path:

Then I created a VPB terrain with the same image. I exported paths from
Google Earth to KML file, got geocoordinates and placed them on the VPB
terrain. Here is screenshot from the VPB terrain:

As you can see, there is a small constant shift to the west.
Approximately 1m. How can I fix this shift? What is the reason for it?
I use osg::EllipsoidModel to convert coordinates. Coordinates in KML
file have a very high precision. For example: 160.1361826749267,
54.43656637255538, 0
Regards,
Alexander
