In 2016-2017, I collaborated with Valentina Gasperini on research into a possible route between the Bahariya Oasis and the Faiyum basin. While Valentina specialised in the pottery evidence and history of the Faiyum region, I researched possible routes using satellite remote sensing. We determined that remains of many trails can be identified in satellite imagery crossing the desert from Bahariya to the Nile valley. Most recently used in historic times, archaeological, ceramic, and settlement evidence suggested these trails have ancient antecedents and may be the same routes referred to Pharaonic and Greco-Roman texts.
I combined medium resolution Landsat-8 and high resolution Worldview-2 satellite imagery to identify various trails across the Sahara between the Bahariya Oasis and the Nile valley. Analysis of the multi-spectral data revealed that desert trails appear relatively clearly in medium resolution satellite imagery where the desert surface remains largely undisturbed. The trails appeared particularly clearly in the thermal infra-red bands. The high resolution satellite imagery made it possible to track the trails across distrubed areas of the desert, while historic maps provided more recent names for the routes and evidence of their use in recent times.
