If you stitch together photos, sometimes something that crosses the join will be in one image and not the other. I submitted something very like this some time

If you stitch together photos, sometimes something that crosses the join will be in one image and not the other. I submitted something very like this some time ago: http://maps.google.com/maps?q=(50.333689,-4.149201)&hnear=%2B50%C2%B0+20+1.28%22,+-4%C2%B0+8+57.12%22&ll=50.333689,-4.149201&spn=0.013834,0.038495&z=15 http://maps.google.com/maps?q=(50.333689,-4.149201)&hnea... Make sure you have satellite imagery turned on. In this case the two overlaid images give you two copies of the breakwater.
