The UJA use GPR to locate the extents of antiaircraft shelters from the Civil War.
The Councilor for Culture, Tourism and Heritage, José Manuel Higueras, visited one the sites in the city where the UJA are using GPR to determine the location and extent of antiaircraft shelters from the Civil War. This is part of the “Identification, analysis, cataloguing and assessment of the defensive military architecture from the Spanish Civil War in the Province of Jaén: heritage education and historical awareness” by Professor Santiago Jaén. Higueras stressed that the city of Jaén has many anti-aircraft shelters, “from before the war, which remain after it” and these survey works “will allow us to discover their location in the ground non-intrusively.
Sandberg has carried out several surveys on World War 2 bunkers in the UK. These included determining their location, extent, depth and construction detail. If you need to locate a buried bunker or determine the construction detail/wall thickness, perhaps we can help you?
