Sarah Helen Parcak is an American archaeologist and Egyptologist,[2] who has used satellite imagery to identify potential archaeological sites in Egypt, Rome and elsewhere in the former Roman Empire.

In partnership with her husband, Greg Mumford, she directs survey and excavation projects in the Faiyum, Sinai, and Egypt's East Delta.

[6] Parcak's work consists of trying to find minute differences in topography, geology, and plant life to explore sites from a variety of cultures, although Egypt is her specialty.

[5] In partnership with her husband, Dr. Greg Mumford, she directs Survey and Excavation Projects in the Fayoum, Sinai, and Egypt's East Delta.

The Egyptian government decided to "develop a nationwide satellite imagery project to monitor archaeological sites from space and protect them from looting and illegal house construction and other encroachments.".

[14] The same year, satellite images from Parcak and her team claimed to have identified the second-known Viking site in North America, located in Newfoundland.

Her team also identified a large ceremonial platform in Petra and worked on satellite mapping the whole of Peru for the crowdsourcing project called GlobalXplorer.

She identified possible sites in Romania, Nabataea, Tunisia, and Italy, including the arena at Portus, the lighthouse and a canal to Rome beside the river Tiber.
