Embodiment Construction
[0075] For above technical problem, the invention provides a kind of urban impermeable layer coverage rate remote sensing estimation method (UISP) estimation method, comprising steps as follows:
[0076] S1. Calculate normalized difference vegetation index (NDVI), normalized difference building index (NDBI), and land surface temperature (LST) based on multiple spectral bands of medium-resolution remote sensing images.
[0077] The specific formula is as follows:
[0078]
[0079]
[0080] The calculation of the surface temperature requires that the images must have thermal infrared bands, and the single-window algorithm is used to calculate the surface temperature. For the specific algorithm, see the following article. "Xie Yuanli et al. Research on Land Surface Temperature Retrieval and Urban Heat Island Effect of Lanzhou City Based on TM Image"
[0081] Wherein, NIR is the spectral value of the near-infrared band, R is the spectral value of the red band, and MIR is t...
