In November 2004, Archeological Institute of Shaanxi Province and Geological Investigation Bureau of China applied shovel drilling and geophysical exploration that confirmed the location of the Westward Tomb Passage, the Underground Dam and the Underground Palace of MEQ were in accordance with the remote sensing interpretation results. After two months' hard working, what we had interpreted were proved right by the results of both drilling and geophysical exploration.
In spring of 2006, Archeological Institute of Shaanxi Province selected 8 anomaly areas to confirm the remote sensing interpretation results by shovel drilling in Shenhe tableland.
They found that 7 of them had ancient tombs and relics.
In these 8 anomaly areas about 46 ancient tombs, 8 ancient rubbish pits,hundreds of recent and contemporary tombs and about 10 ancient active loess pits were found.
Figure 5 and Figure 6 show hyperspectral information extraction and verification of No.1 anomaly area.
