Below is a link to a web site that provides a summary of remote sensing technologies that can be useful in treasure hunting.
Included are the following:
Aerial photography
Geographic Information Systems (GIS)
Geophysical Diffraction Tomography (GDT)
Ground Penetrating Radar (GPR)
Imaging radar
Infrared aerial photography
Magnetometer
Seismic vertical profiling survey
Soil resistivity mapping
Thermographic Infrared Multispectral Scanner (TIMS)

That will keep you busy for a while if you think about how those can be used.
On a similar note, sometimes you can tell where there was a settlement or human activity in the past by looking at the plants. Some plants were commonly used for landscaping or ornamental purposes. They can provide a clue to an old home site, for example.
Other plants were used for other things and might provide a clues to the past.
The Gumbo Limbo tree was used for posts. They would often take root and can indicate the boundaries of an old stockade, fence or burial ground.
I've heard that the Native Americans sometimes marked grave sites with a Gumbo Limbo tree at each corner. Don't know how true that is. Old timers have told me to look for big old Gumbo Limbo trees too.
Here is what they are doing at Fort Pierce Beach (See video below.). It seems like they are dumping sand there continually. As long as they have the money to throw around! It's actually my money and yours getting circulated. Good thing there is no end to it. At least that is how it seems the way they spend it.
I saw tourists trying to find a place where they could go to the beach, and some laying right by those ugly big pipes and with all the noise of the heavy equipment - not really a pretty sight.
I went out to the beach today hoping to dig up a few targets I couldn't recover a few days ago. I wasn't successful. The water was still too high and rough for me to be able to dig those deep targets.
They were digging tons of muck up out in front of the Fort Pierce Marina. There was a lot of junk in it. Who knows what else?
The surf on the Treasure Coast today was around two to three feet and predicted to decrease to one foot this weekend, then next week increase again.
I'm still hoping I get a chance to dig those deep targets before they are more deeply covered or moved. That is not looking good now.
I found a really great book that I'll talk about a little tomorrow. Not enough time today.
Happy hunting,
