ancient architecture art capital egyptian four great hundred kingdom middle period site thousand time
Itjtawy was ancient Egypt's capital for over four hundred years, at a period of time called the Middle Kingdom about four thousand years ago. The site is located in the Faiyum of Egypt, and the site is really important because in the Middle Kingdom there was this great renaissance for ancient Egyptian art, architecture and religion.
advanced against ancient discovered egypt less percent population protect race time
Less than 1 percent of ancient Egypt has been discovered and excavated. With population pressures, urbanization, and modernization encroaching, we're in a race against time. Why not use the most advanced tools we have to map, quantify, and protect our past?
amount everywhere issues limited site sites time
We have so many issues with overpopulation and urbanization and site looting. And this isn't just Egypt. This is everywhere in the world, even in America. So we only have a limited amount of time left before many archaeological sites all over the world are destroyed.
bring covered difficult dollars favorite growing hard sand
When I was a child growing up in Maine, one of my favorite things to do was to look for sand dollars on the seashores of Maine, because my parents told me it would bring me luck. But you know, these shells, they're hard to find. They're covered in sand. They're difficult to see.
commercial discover high map nasa past resolution satellite
'Satellite archaeology' refers to the use of NASA and commercial high resolution satellite datasets to map and discover past structures, cities, and geological features.
aircraft beneath cities entire forest future light literally measured rain return sends strip system thousands vegetation
There's even an aircraft sensor system that sends down hundreds of thousands of pulses of light measured at different return rates. It allows you to literally strip away vegetation and see entire cities beneath the rain forest canopy. This is the unbelievable future of archaeology.
affect beneath buried changes depending ground imagery landscapes map radar remains satellite scientists technology
The only technology that can 'see' beneath the ground is radar imagery. But satellite imagery also allows scientists to map short- and long-term changes to the Earth's surface. Buried archaeological remains affect the overlying vegetation, soils and even water in different ways, depending on the landscapes you're examining.
cultural features ground model seen using
We're using satellites to help map and model cultural features that could never be seen on the ground because they're obscured by modernization, forests, or soil.
cia cold credit dr full harold mapping professor russian spy university war worked
I give my grandfather, Dr Harold Young, a forestry Professor at the University of Maine, full credit for my career path. He pioneered the use of aerial photography in forestry in the 1950s, and we think he worked as a spy for the CIA during the Cold War, mapping Russian installations.
map moved time violent
If you look at the Nile on a map of Egypt, you don't think it has moved very much, but the river is very violent and has moved over time.
available field fortunate gave imagery military spying useful
Archaeologists gave the military the idea to use aerial photographs for spying and field survey. We are fortunate that the spatial and spectral resolutions of the imagery available to us are so broadly useful for archaeology.
To excavate a pyramid is the dream of every archaeologist.
couple focused good grab playing poor rebounds shooting suddenly wake
We've been working on our defense. We could have a poor shooting night, but suddenly we grab a couple of rebounds and we wake up. Our lapses are always when we're not playing good defense. It's something that Lourdes has always focused on.
