A method for inversion optimal model of water quality total phosphorus parameters based on satellite data |
| abstract |
The invention discloses a method for obtaining an optimal model for inversion of water quality total phosphorus parameters based on satellite data. The method includes: step S100: extracting the L2A level data of Sentinel No. 2 according to requirements, and performing data preprocessing on the data; step S200: according to the actual measured points The latitude and longitude data are extracted to extract the reflectivity of the remote sensing bands at each point; Step S300: Compare the extracted reflectivity of each band of each calibrated water body point with the total phosphorus concentration data measured from each on-site water quality monitor. Correlation analysis; screen out each band or each combination of bands greater than the correlation threshold from the correlation calculation result; step S400: establish different regression models based on different correlation analyses; regression models include but are not limited to single-band regression models, multiple Band combination regression model; Step S500: Perform error analysis on different regression models respectively, and confirm the optimal model for inversion based on the error analysis result. |
