Photo-based Measurementation of the Wick Effect and Gradient at an Urban English Churchyard (Scarborough, UK)
Author(s): Mary J Thornbush, and SE Thornbush
Headstones located at St Mary’s churchyard situated in Scarborough, UK were photographed with a scale and measurements taken of
distinctive wick tides. These were measured at maximum height on the front of headstones. Out of 339 headstones photographed in this
study, 76 (22.4%) had (distinctive) lens-shaped wick tides. Measurements of maximum wick height were acquired both through photographic
means and compared with some field-based measurements. Topography was also photographically assessed as well as examined remotely
using online-accessible Google Earth satellite images. The photographic measurements in the current study were very comparable to those
attained either in the field or remotely. It can be concluded based on the findings of this study that digital photography can be manipulated to
acquire accurate measurements of such physical attributes affecting headstones as cultural heritage landforms located in an urban churchyard.
The level of accuracy possible in this study was within a 5% error margin, which is adequate for most research purposes.
