Detection of Archaeological Residues using remote sensing

Techniques (DART)

'Diurnal experiments at Cirencester (16July 2102). We proposed a thermal imaging experiment at the RAC in Cirencester. This was originally instigated after viewing the diurnal temperature variations from the embedded probes and wondering what the impact of the vegetation canopy would be on any sensor. This was given life with follow up conversations with John and Rosie Wells (West Lothian Archaeology).'

Cherry Copse

The scaffolding goes up at Cherry Copse while David Stott considers alternative employment as a highly qualified grass strimmer.

It did not look this high from the ground!

The temperature calibrated thermal imager (left) and the PathFindIR thermal imager on the scaffolding.

The PathFindIR was connected to a battery power source (through a voltage stabiliser) and digital video recorder (on the chair) with 21m of power/signal cable. A small personal video recorder (on top of the DVR) was used as a monitor. A generator powered the DVR and PVR.

 

 

The neighbours ignore our presence.

(Not to be confused with thermal imaging - thermal data being analysed)

Not quite as marked in the strimmed area.

At this point, Dave and Ant had been taking still thermal images from the top of scaffolding continuously for ~48 hours.
