A time-series ortho-product data set of returning farmland to forest area on the Loess Plateau

Firstly, landsat-8 full-color orthomosaic images were used as reference images, and image control points were obtained by the automatic image matching method. Secondly, the L1 norm-constrained least square method was used to modify the RPC model with the image.

Finally, the original image was orthorectified based on the modified RPC model and DEM data. The image data (spatial resolution is 16 m) includes visible light and near-infrared bands and the plane geometric accuracy is better than 2 pixels. This data set can provide data support for in-depth study of the effects of returning farmland to forest and grassland on the Loess Plateau and its ecological and economic effects.
