In ArcMap 10.5.1 I am accessing two orthoimagery basemaps from ESRI
online--one is the World Imagery the other is one of our State orthoimagery
datasets being hosted by ESRI online. I also have downloaded tiles of the
state orthoimagery. 

 

I noticed that there are positional differences when comparing the two web
map serviced layers--the image shifts about 10 feet when displaying one
versus the other.  The tile and web map versions of the state orthoimagery
have identical positioning.

 

I would be surprised that this would be normal to have such a displacement
in position. What could be causing this issue and how would I either fix it
or at least know which data set is causing the issue?  I need to use the
state ortho as it is leaf-off and a higher resolution but I am wondering if
something may be wrong with its data.  

 

Thanks, 

 

Wayne
