Area resistance survey can provide detailed plans of building
foundations and other stone structures, along with ditches and
pits. At its best it can provide “building plans”, but
can also be an effective application on those type of monuments
where magnetic enhancement is limited or unlikely to have occurred
(e.g. burials and barrows).
This technique passes a small electrical current through the
ground and measures the resulting resistance. This technique
is ideal for locating walls, foundations and paths but can also
detect ditches, pits and drains. Whilst slower than
gradiometry this technique has recently seen a growing resurgence in
its application, possibly as it is largely unaffected by geology and
for its ability to discern such ephemeral features as flower
beds, paths and graves.
We use a Geoscan RM15 with muliplexer, which is two
sets of “sensors” put together to cover an area faster.
