Remote sensing with 1-m resolution infrared satellite imagery has allowed US Egyptologist Dr Sarah Parcak to discover a multitude of new archeological sites in Egypt. Her work was the subject of a BBC documentary where after over a year of data analysis and interpretation, she went to Egypt to perform several test excavations where her team’s imagery analysis was confirmed. The bricks that were used by ancient Egyptians to build their structures were more dense than the surrounding soil, allowing them to be seen on the satellite imagery, even when buried. There is a quote from Dr Parcak that I think is fantastic:
Indiana Jones is old school, we’ve moved on from Indy, sorry Harrison Ford.
The Google Earth Blog link has some links to the imagery and Google Earth files that show some of her work.
