Ground-penetrating radar (GPR) is used to detect burials and ‘usable’ space throughout a graveyard.
GPR uses the transmission and reflection of radio waves. Radar waves, introduced in the ground, may reflect back to surface when they intersect various objects or surfaces. These results will be related to the interactive maps and shown in a specific colour to distinguish these from the normal plots.
The only requirement the need to conduct GPR is to have is access to the grounds for the duration of the survey. The process in no way disrupts the graveyard or causes any disruption to the plots or headstones.
