| Abstract: | We first discuss the relativity of true value and homogeneity for quantitative remote sensing products (QRSPs), and then propose the definitions of eigenaccuracy and eigenhomogeneity under practical conditions. The eigenaccuracy and eigenhomogeneity for land surface crucial parameters such as albedo, leaf area index (LAI), and surface temperature are analyzed based on a series of experiments. Secondly, we point out the differences and similarities between the scale-free phenomena of the QRSPs and the measur... |
