The oldest references I found with a quick Google were about 10 years ago. I thought it was longer ago than that but CRS could be a contributing factor there.
It's not quite that useless. In the hands of an expert photo recon interpreter they can focus in on likely spots.

Quote:Sprajc and his team went on the hunt for Chactun after looking at some aerial photos of rainforests in the Mexican state of Yucatan. "With aerial photographs examined stereoscopically, we found many features that were obviously architectural remains," Sprajc said in an institute statement. "From there we took the coordinates and the next step was to locate the ancient alleys used by tappers and loggers to reach the area."
Almost anything is more effective than simply digging dry holes on hunches.
