No, I do not work for NASA. I work for everyone really; my organization is about research and education, but we're not operated for profit. I'm just an old run of the mill archaeologist; well, actually, diachronic anthropologist (which I'd love to explain over the course of 1 hour and 15 minutes, 3 days a week, for 16 weeks).
Here are some examples from some recent work:
1. General Land Office (GLO) Map from the early-mid 1880s, over which I've plotted the settlement pattern of two different communities.
2. After consulting the GLO records regarding the original land grants, I plot those properties over the earliest aerial I have for the county. It's from 1938, and the image is stitched together of many smaller aerials of that flyover--the full image's file size is enormous.
3. This image shows the properties over a 1958 County-produced road map (another large file in full). This period reflects some intrusion by industrial interests, and the community center has shifted slightly north from the original focus.
4. The last photo is unrelated to the area of the previous images, but the next phase will be to do some type of sub-surface exploration in the area of my new project. The photo shots an excavation unit, with the top of the natural surface just barely exposed. The road was built on top of a white sand dune in the early 1920s.
Interestingly, I found the that former roadbed of sand and shell had cemented together to become fairly impermeable. There was clear staining from the road bed level, all the way to a meter below the surface. The same type of drainage pattern could be expect anywhere such a loose substrate is not protected from road pollution by adequate drainage. In this case, it was draining right into a waterway that was a steady spring-fed run leading to a protected bay.
