Scope of Work:
GPR survey execution for mapping of underground archaeological artifacts
Location:
Kadapa, Andhra Pradesh, India.
Client:
Capstone Geo Consultants Pvt Ltd.
Equipment:
GSSI SIR-3000 equipped with 100, 200 MHz and 400 MHz antenna
Challenges:
Undulated land for data collection, weak signal GPR data, challenging data interpretation due to uncertainities
Summary:
The scope of the project includes the mapping of around an acre area using GPR to
cover the depth upto around 10-12 m to map all the possible potential locations for the
existence of any archaeological features. The area has been scanned using 200 MHz and
100 MHz antenna for maximum depth of penetration with optimum resolution. Various locations have been marked using GPR for the probability of the existence of
the possible archaeological features . In this GPR survey, an area of around 2800m2
has been scanned in 3D mode to detect the possible locations containing any archaeo-
logical artifacts. Various locations with possible existence of metallic features have been
observed beneath the subsurface. Few locations were even cross checked in across and
along profiles which confirms their existence, however, couple of locations were found to
contain intense reections,though could not be confirmed in across profile. Moreover,
the smaller area scanned in front of farm house also found to contain some features
which are expected to be metallic. Hence, GPR survey has been successfully executed
to locate potential locations at an site situated in Kadapa in Andhra Pradesh.
