[Qgis-user] aligning ortophoto with google maps and google earth

[Nigel Berjak - General]

Hi Radra

A word of caution.

Please be careful to think that Google Earth is more accurate than your 
drone aerial imagery. Google Earth imagery suppliers may not have a DEM 
that is accurate, often for places/locations that are not considered 
high-value e.g. places likely to be visited by people on Google Earth, 
those that have not been commissioned at a high level for spatial 
accuracy etc. You would need to determine from the imagery source of the 
Google supplied imagery, what that scene is produced at. If you have a 
national spatial body for your country, it is likely their DEM will be 
more accurate.

However, in saying all this, you may simply want it aligning with GE 
imagery, for other purposes and then please disregard my email.
