We implemented the proposed scheme to a cloud computing platform of Google Earth Engine and generated a novel dataset of China's annual cropland at a 30m spatial resolution (namely CACD). Results demonstrated that our approach was capable of tracking dynamic cropland changes in different ...
(China Crop Dataset–Maize, CCD-Maize) identifying maize in 22 provinces and municipalities from 2001 to 2020. The map was produced using a high spatiotemporal resolution fused dataset and a phenology-based method called Time-Weighted Dynamic Time Warping. A validation based on 54,281 field ...
(Fig. 1). In 2017, 758,084 ground samples of crop types, 1,128,000 photographs and 2.57 TB data in 1381 counties of China were quickly and efficiently captured with this app in 70 days; these data have been used to support the 2017 paddy field/dry land identification and other land ...
In some Southeast and Northeast Asian countries, single-crop maps were produced, such as the NESEA-Rice10 (Han et al., 2021a), the RapeseedMap10 (Han et al., 2021b), and the rice-cropping and cultural type dataset (Manjunath et al., 2015). In China, the CropWatch system has been ...
(temperature, precipitation, radiation and wind speed) needed to calculate potential evapotranspiration (PET). Because of the high spatial variability of precipitation, the closest grid point in the ANUSPLIN dataset to both SLZ and STEL sites was selected and used in the calculation to better ...

In addition, croplands are abundant in the middle and lower reaches (shown in Figure 1 by 30 m Global Food Security-support Analysis Data, GFSAD30, cropland distribution product (Oliphant et al. 2017)). Samples were randomly selected from the study area for all subsequent experiments. For ...
ESRI [17] even used a super-large dataset of Sentinel-2 with a total of more than five billion samples in the production of 2020 LandCover, which has a resolution of 10 m. In the process of matching samples and remote sensing images, the extraction of spectral features and indices of ...

Since 1999, the Chinese government has implemented the Grain for Green Project (GGP), which requires that croplands with a slope greater than 25° be restored to grassland or forest (Li et al., 2018), and 60.9–84.8% of the existing steep cropland has been restored; thus, land use and...
