Spatially explicit subpixel-based study on the expansion of impervious surfaces and its impacts on soil organic carbon

Impervious surface extraction and spatiotemporal analysis in the main urban area of Zhengzhou

“…A LSMA model [14][15] was employed to map the impervious surface of Zhengzhou. The LSMA model is a sub-pixel image processing method, assuming that the spectrum of a certain pixel measured is a linear composition of all spectral values in a mixed pixel 16 .…”
