Abstract: Most studies on the inversion of heavy metals in soil in large areas are based on the measured hyperspectral data. However, the field spectral data acquisition requires large workload, high cost and long time. This paper attempted to obtain spectral information directly from worldview-3 satellite remote sensing image, combined with a small number of measured geochemistry samples, and established a model through regression analysis to invert heavy metal As in soil in the Western Tianfu New District. It is equivalent to a spectral acquisition on each pixel, which replaces the traditional field spectral acquisition and saves the workload. The results show that the content distribution of the inversion results is basically consistent with the measured results, and the distribution trend of heavy metal content can be well demonstrated. This method can greatly reduce the cost and realize the rapid, non-destructive and normalized monitoring of heavy metals.
