That's pretty cool though. My major happens to be geography, which works with aerial and satellite imagery in a technology called remote sensing. I'm only an undergraduate student but I've been thinking of doing something like this for a class project. In remote sensing, sensors scan Earth in multiple wavelengths, which in turn can be used to calculate soil moisture, plant health, and surface temperature. Objects under the ground affects how much soil is under the ground while ditches fill with a loose soil that retains moisture better, therefore how much moisture it can hold, which is why the vegetation varies in greenness levels to reveal objects under the soil. In some sensors, scanning can act like radar, but I think this only works in dry areas since it's microwave-based. Lidar can also be used for finding some things with drones and airplanes. I actually don't know much else about archaeology techniques with remote sensing but I'd like to learn more if given the opportunity. My free time is already occupied with learning finance online and other stuff.
Something else to bring up on this subject is that Landsat 9 is going to launch soon. 9 is an important number in Norse mythology and NASA put a rainbow on the logo, like the rainbow bridge Bifröst. NASA even put a Viking on Mars, and named an asteroid "Ultima Thule" which happens to resemble a snowman.
