Hello,
I have found a curious issue with the Bing Basemaps (Hybrid). If one pans to the Iraq-Jordan border, with the bing hybrid basemap, and zooms to 1:900,000 scale, make a note of the position of the border, if you zoom to under 1:866,000 the border shifts 10.3km to the east.
Why is this? I guess it is a bad correlation between raster satellite data as the image source changes through zooming. Any thoughts?
