    Hi I'm expierienced in 3d models from air shots and I1 is doing a great job with its geo-tagged stills.

    All is fine but when we try to put the 3d scenario on maps like Google Earth the entire area is like shifted from the Google map.

    It seems that the GPS scale numbers of Google Maps are in a different version.... anyone know which is the conversion rule?

    Thank you

    I read some where that geotagged photos are not that accurate of mapping applications so maybe its the same for 3D image models.

    I use ground control points to georeference mossaics and it overlays pretty accurately. Google uses Google Mercator projection. EPSG:900913.

    Thank you, actually the accuracy for our work is enough, the problem is the difference with Google scale...
