I am after some tips and techniques on spotting terrain differences, I have been studying aerial shots of an area, and I'm looking for a buried shipwreck. How I could I spot a buried shipwreck? EG: Lack of trees growing, increased erosion, discolouration of the sand, maybe even a kind of bog hole?
I believe I have found a possible site of interest. Its located near a inland Lake that has a surface area of 7.3 hectares and a maximum depth of 9.4 meters. The lake is a depression that extends below the island?s water table. The Lake is approx 1.2miles from the shore line. Therefore it is possible that 400yrs could equal 1.2miles of sand build up? And it is also possible that 400yrs ago this was a bay?

A) I owuld suggest separating your basic colors and studying the photo carefully in each. This technique is what originally lead me to the Tayopa mines. With it I also located the "SUN" sign which is important for one of the main depositories, even the local Indians did not know of it, hehehe...

A) I would not put too much faith on present contours etc.. I have seen them change radically with just one major storm - however do not discount them either . (briliant statement no?) hehehe. And YES, it could easily be a bay.

While it may be correct, i don't think this conclusion is supported by the information given. Just my opinion.
I do think the other 2 suggestions (color seperation and infra-red) might reveal otherwise invisible detail.

LUCK!!
p.s. Hectares & Meters = Canada?
When you say separate basic colours, do you mean changing the HUE/SATURATION ?
I know what you mean about the contours, the wreck is on a sand island, which means the terrain is changing all the time, the wreck has pop up after a couple of major storms back in 1880's and 1910's, but quickly hidden again.
Hectares & Meters = Metric Canada is a good guess, but I'm on the other side of the world
Have a look at these two photos and notice the coast line changing, its quite amazing.

You can use a photo editing program to view the separate red, green, and blue channels. Usually you get a B&W rendition showing the relative values of each channel.The first image shows all three channels, the second shows only the red channel. You can also mess with the blending options, as shown in the third image.
