Popis:	The Geophysical Institute of Israel (G.I.I.) carried out a Ground Penetrating Radar -- GPR -- survey at the construction site for the administration building of the I.E.C. (The Israel Electricity Company) in the town of Ariel in the Samaria mountains of Israel. The construction workers at the site found a void in one of the pile boreholes and the GPR crew carried out a survey to detect and map the cave. The GPR data show a very clear 'cave shape' with an area of about 81m2, the roof of the cave was at a depth of 5m - 7m, while the floor of the cave was at a depth of 8m - 11m. The volume estimations of the target were incorrect and the construction workers did not find any indication of the existence of the cave under the pile sites except the one prior to the GPR survey.© (2000) COPYRIGHT SPIE--The International Society for Optical Engineering.
