I have always been an opponent of those who've claimed that Google Earth can and does manipulate the imagery it provides to us. They usually cite
that these manipulations are usually carried out by GE and done at the request of the government/military to remove or make less obvious various
"sensitive" data that may have been imaged unintentionally.
But finally, I have to change my long standing attitude and agree with them that yes, when necessary, Google Earth does in fact manipulate the imagery
it feeds us as the following examples will show.
The rightmost image was obtained from GE approx 6 months ago ... the leftmost image was obtained from GE today (10 July, 2009). Even though the
original image was not of high quality, sufficient detail was still visible to show significant structural details. Now compare that original image
with the latest one. It's immediately apparent that significant image degradation has been applied and a lot of the structural detail originally
visible has now been lost.
Now why am I concerned about this loss of detail ?
The original image was located by myself in the military restricted southern Papoose mountain range of Area 51 not far from the infamous S4 area. I
had a PERSONAL theory regarding this image but initially didn't make much of a big deal about it. But in the last couple of months I've been
displaying this image on various online forums and truthfully receiving what can only be described as entirely abusive feedback so I'm NOT going to
bother peddling my PERSONAL viewpoint here.
But suffice it to say that the online GE version of the image remained untouched and unaltered for months UNTIL I began showing it to others online
and then shortly afterwards I find that GE have "manipulated" and "degraded" the data content of the image.
Now why would they do that if there was nothing to hide ?
Obviously removing by "photoshopping" the image would have immediately indicated that there was something of extreme interest to be seen there and
so the next best option was exactly what has happened ... leave the image intact but significantly degrade it and make it less obvious.
The image below gives a slightly better view ... all that I have done is to increase the contrast, brightness and colour saturation to try to bring
out additional details ... otherwise COMPLETELY UNTOUCHED.
Anyway, just wanted to post 100% confirmation of GE image manipulation.
