For those who seem to have not bothered (it helps to follow the thread).
The source image which Google used is from ESA's Mars Express orbiter, using the high resolution stereo camera. The image ID: H5620_0000_ND2
You can find it here:
HRSC viewer
If you want to download the full image you can get it here:
psa.esac.esa.int...
It is large, 355 MB. You will need a viewer to decode the image. You can get that here:
pds.nasa.gov...
This is what it looks like at full native resolution:
This is what it looks like zoomed 300%
It is obviously an image artifact in the source image. Note the one pixel spacing. Note that the pixels are in a horizontal line across the
image.
