Our primary interest is the use of low-level
photography. We work mainly in the visible and infra-red
parts of the spectrum, but we may extend our work into the near
ultra-violet, if appropriate.
Previously, we relied on the generous support of
the Edinburgh Archaeological Field Society, and Dr Peter Morris, for
geophysical survey work. At the
beginning of 2010 we were joined by Jim Knowles, a professional archaeologist with extensive
experience in geophysical techniques. Jim is the group's
archaeological lead and is also responsible for all geophysical work.
In June 2010, we received an MM
Instruments 216M resistance meter from Prof.

Instruments 216M resistance meter at Blackness
We use the
excellent freeware package
to process our earth resistance data. This has proved invaluable for
our community group needs, but it is always interesting to try out and
learn to use other packages. One such piece of software is the new
ArchaeoFusion geophysical package, developed by the Centre for
Advanced Spatial Technologies at the University of Arkansas. It is
aimed at archaeologists using a multi-sensor approach, to quickly and
easily process and integrate multiple data sets. It can be used with
different data collection platforms from GPR, magnetic,
electromagnetic, MS and resistivity methodologies. The data can be
easily processed using its straightforward interface and integrated
into a processed representation using a suite of useful processing
The software is still in an early beta phase of development. Jim has
signed up to the beta program and has been testing its features, using
our collected earth resistance data, with promising results.
Eventually, Jim hopes to combine data
from kite aerial photographic surveys (Infra-red, thermal,
ultra-violet, and visible spectrum photography) with ground based
(Metal detecting, field walking, chemical, earth resistance,
electrical resistance tomography, magnetic and digital terrain
modelling) surveys, as a more integrated approach to data presentation

In May, 2013, we added a Geoscan
Gradiometer to our equipment.
