Abstract: Highlights•Soil parameters inversion using a VAE style-based spectral fusion model.•Merging satellite-based hyperspectral data and indoor ASD hyperspectral data.•The R2 values of the SOM, As, and Cu contents are all greater than 0.8.•The VAE-based model can remove substantial noise, preserving spectral features.
