New archaeological survey instrument
Development of a device combining the functions of a cesium magnetometer and an RTK GPS set subsidised by Foundation for Polish Science under the programme NOVUM. It is a non-invasive equipment for archaeological prospecting.
The creators of the innovative device are: Krzysztof Misiewicz from the
Institute of Archaeology, the University of Warsaw and the Institute of
Archaeology and Ethnology PAS, and Wiesław Małkowski from the Institute
of Archaeology, the University of Warsaw.
The result of the merger of combining two instruments is a system for
simultaneous measurements of magnetic field to detect underground
structures, and very precise geographical position in the GGA format.
"In
practice, this means that the instrument enables a very fast and
precise measurement of land surface - the so-called micro-relief,
simultaneously recording the data with the cesium magnetometer G-858
Magmapper, which measures the magnetic field every 0.1 seconds" -
explained Wieslaw Malkowski, one of the constructors.
The results
of field work provide the most accurate data, illustrating the space in
the form of 2D and 3D models and maps. Recording a large number of
measuring points, about 40,000 in each hectare, allows to obtain
comprehensive information on the analysed area. Also possible is the
data set interpretation on the basis of maps, as well as data processing
in conjunction with aerial photographs or satellite images.
The
new device has already been successfully applied at sites Ptolemais in
Libya (research of Institute of Archaeology, the University of Warsaw),
Tell el-Retaba in Egypt (research of the Centre of Mediterranean
Archaeology) and Wicina in Poland (the project of the National Centre
for Research and Documentation of Historical Monuments, now the National
Heritage Institute).
"The results of the first tests confirm the
initial assumptions adopted during the design phase of whole device.
The data set is stored in one ASCII file, and the instruments do not
cause any interference" - said Małkowski.
