4. CONCLUSIONS AND DISCUSSIONS
This research demonstrates that hyperspctral remote sensing is
effective for archaeology even when no ground remnants or
other traces are found. Hyperspectral remote sensing could
detect and identify weak spectrum differences of ground objects,
and it deserves to penetrate the archaeological research. The
selection of hyperspectral remote sensing time for archaeology
is important. And the best season for hyperspectral scanning is
when crops have been harvested and the soils have been
exposed to insolation for a longer time. Shallow-buried tombs
usually lead to less moisture and higher thermal anomalies of
the covering soil. Thermal infrared image scanned at nighttime
is more effective for temperature anomaly detection than that at
daytime.
To the authors’ knowledges, if an underground building is large
in scale, geometric shape is regular and physical property is
distinct, the spectral anomalies will be much clear. Some ash
pits filled with rubbish or bones will change the thermal
properties and spectrum of overlying objects due to lower
density, higher fertility and more diversified humidity.
Therefore, the size of detectable cultural relics relies on spatial
resolution of image, larger relics or group of small relics
densely distributed will be more detectable by hyperspectral
remote sensing because they can more possibly cause anomalies
in thermal properties and vegetation growths.
The scanning time for hyperspectral image in Shenhe tableland
was a little late, and the ground crops had been already 5~
1 Ocm high, and the percentage of vegetation coverage reached
to 60~70%. The spatial resolution of image was about 3.6 m.
The lower resolution had had a disadvantageous influence to the
results of studying.
