I. Dataset content features
i. Abstract
The datasets are remote-sensing data on the resources and environment of the Loess Plateau, and mainly record data on soil erosion, land use, land resources, soil, forest resources, vegetation, and grassland resources from 1987 to 1990. They are collected and organized by Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, and include Erosion Map (1987-1990), Land Use Map (1987-1990), Land Resource Map (1987-1990), Soil Map (1987-1990), Forest Map (1987-1990), Vegetation Map (1987-1990), Grassland resources map (1987-1990). There are totally 7 data files in .adf format. They can be used to study the changes in resources and the environment in the Loess Plateau, and government decision-making.
ii. Elements (content fields)
The datasets are named as “Remote Sensing Series of Loess Plateau Resources and Environment from 1987 to 1990”, which include 7 data files. There are mainly 7 data name and they are described as table 1.

V. Quality control of the dataset/atlas
i. Data sources (condition selection)
ii. Methods of the data acquisition and processing (condition selection)
Through correction, shear and exponential calculations, data are obtained to obtain remote sensing data of resources and environment in the Loess Plateau. Data processing software includes ArcGIS and ENVI. First, the acquired remote sensing data is corrected and processed. Then, we use ArcGIS for index calculation and classification. Finally, we add the above result to get the rasterized resource environment data.
VI. Sharing and usage method of the dataset/atlas
i. Sharing methods and restrictions
Full and open sharing.
ii. Contact information of the sharing service (condition selection)
