Abstract

This paper discusses the method of detecting the palace area of the capital city site by using the land surface temperature retrieval and downscaling taking Erlitou site in wheat coverage period as an example. Land surface temperature was retrieved from Landsat 8 multispectral data on May 6, 2014 using radiative transfer equation method. Then, the mathematical relationship between the retrieved LST and NDVI is established to realize the downscaling of LST data and improve its spatial resolution. Compared with the results of archaeological excavation, it is found that the geographical location and scope of the palace area of the capital site can be well reflected through the downscaling of land surface temperature image, which provides a feasible method for the satellite remote sensing detection of the early capital site.
