摘要: More than 1,000 years ago, several dotted, flake-shaped sections of the Great Wall stoodin Xinjiang, protecting the border and the trade road.

More than 1,000 years agoseveral dottedflake-shaped sections of the Great Wall stoodin Xinjiangprotecting the border and the trade roadRecentlyresearchers from the ChinaInstitute of Remote Sensing and Digital Earth (RADIunder the Chinese Academy ofSciences (CASanalyzed the distribution of ancient Great Wall sections in Xinjiang usingremote sensing technologyThey also used the technology to "restorethe wall'sappearance.

Remote sensing archaeology entails the use of electromagnetic waves and other sensors forlong-distance observation and detection of surface and underground remainsAerospacedevelopmentand especially the increased resolution of remote sensing satelliteshasprovided greater precision and a more efficient platform for remote sensing archaeology.

Nie Yuepinga researcher at RADIexplained that electromagnetic waves produced byvegetationsoil and geomorphology are different from those of historical sitesSuchdifferences cannot be seen by the naked eyeHoweverspecial equipment can obtainelectromagnetic wave data via remote sensing platforms such as space shuttlessatellitesand unmanned aerial vehiclesArchaeological information then can be extracted from thedata through computer processing.

So farmore than 600 ancient remnants of the Great Wall have been foundYu Lijunanassociate researcher at RADIsaid that the team has outlined a Great Wall resourcedistribution lineand are working to "restoreimages of the ancient Great WallThroughvirtual reality technologypeople may soon be able to take an online tour of the remains inXinjiang.

Compared with traditional archaeological methodsremote sensing has many advantages.With the popularization of satellite technologyremote sensing data can be obtained underall weather conditionsMoreoverthe cost of using the technology is relatively lowandcauses little damage to ancient remains
