Bing Maps Curiosity

[SimonKettle]

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?

Hi Simon,

Interesting find.  I noticed that this same phenomenon with the Iraq-Jordan border happens on the Bing Maps site as well.

Ah its possibly on their entire mapping server then, I wonder how that happened and if anyone else has noticed this in other areas of the globe? Or mapping providers?
