The date on this map is 6/15/2015 even though I got it only moments ago. Must be why I could see clouds moving 6/14/2015, satellite live was on during the time. That was so neat, could zoom all the way down, until distance scale (lower left) ended at 30-31 ft and be right on moving clouds.

Here is the same dark area along the reef, not sure if it is a flaw in the GE mapping system or if something is down there....could be large rocks also.

Kevin, this is so real close to where you've been searching. I thought it must be the way they put the images together and the zoomed out a little moving over, lightened it a little and seem more like an outline.....do I dare to hope?

Red what are your thoughts, are there some numbers you think I should check??
 

Hard to tell what is there, go south a little.

Go out on a limb and send me to the best numbers you think. I have been enjoying the lottery of " maybe here" but If you wanna take a chance, send me to a set of numbers....

Pm them, I'll let you know if your a champ or a chump ha ha....
 

I had to go eat supper was assuming it must be the shadow side of a reef, but then experimenting some with hue shift color balance, began to notice a couple shapes. If it is only the reef, could be rocks making those odd shapes. Need to put a pin there, then PM the cords. Might only be rocks, probably doesn't hurt to check.
 

Almost looks like they have it blacked out, but that wouldn't make any sense.

Kevin, I must have been right the first time, that probably is a GE mapping glitch. I'm going to use this pin.

Just a hint; If you are using coordinates from Google Earth, you may need to recalculate. Often the coordinates will be some distance from the actual locations. Especially in th Bahamas. Also there is no visual reliably when you zoom in too close that you see the blocks. Dell

Yes, there can be a gps shift, as you zoom down closer. Some of my own tests, it seemed to be off only one direction and that wasn't very significant....but a little off underwater could make a lot of difference.

I did a test of the software settings used for the maps above, on a map from Key West where the bottom is visible. A big difference in the results. I'll post them here, no bright tint in the map, only darkened it some (2nd map). Not using any special effects or PhotoShop, just ordinary hue/saturation/lightness shift normally used for color balance.

I guess it did have a little tint.....must have cancelled while making a screen capture of my settings.

Makes ya wonder...
If GE offers "a more distorted/obscured view"... for a fee to paying clientele of course.
 

If you had good aerials taken with clear calm water, what could be done is amazing. During the war with the Nazi in France, our government figured it out. Planes flew over areas suspected of having V-launch sites. A team of specialists were given the task of getting intelligence from these photos. Large size prints turned into a certain number of sections, each photographed again. Then large photos made to section and photograph the same way. The result produced a large close up print of the launch ramp and building. Even damage caused by Vs taking off could be seen on the roof.

Much easier to see the snapshot effect, which is built into most imaging software, if a colorful potrait is used instead. At a resolution of 96, the image size jumps from 325 x 361 to 480 x 533, then to 672 x 746, to 864 x 959, to 152 x 1279.

As you enlarge using the snapshot method, every other time a color correction is done.

You can keep going until a cropped section of the head is at a resolution of 96 a print size of 12 x 12 inches. These are hidden software capabilities they don't tell people about.

If you use fractals rather than pixels ...this is enlarged once using fractals to 3600x4000 pixels with no color shift. It's 300 dpi approximately 12x13 inches.

If you zoom in on the south east corner of the Baltic sea, it looks like the submerged remains of a series of 5 or 6 huge old stone docks or quays. i'd bet diving there would probably produce some cool old artifacts, and probably some amber as well.
