Improved Method for Soil Salinity Mapping With Polarimetric SAR

Résumé fourni par la source

In this paper, an improved method was developed to enhance the accuracy of salinity mapping. Soil salinity qualitative classification was performed based on the soil salinity. Salinized soil was categorized into three grades. The soil salinity in each grade was accurately predicted using GA-PLS. When compared to predictions without classification, a significant improvement in accuracy was observed with the classification approach. This demonstrates that the modeling accuracy can be significantly enhanced using the improved method. GA-PLS proves to be effective in identifying the dominant variables for soil salinity inversion across different grades of salinized soil.
