高分六号于2019年3月21日正式投入使用，它是一颗低轨光学遥感卫星，具有高分辨率、宽覆盖、高质量和高效成像等特点，配置2米全色/8米多光谱高分辨率相机（PMS）、16米多光谱中分辨率宽幅相机（WFV），2米全色/8米多光谱相机观测幅宽90公里，16米多光谱相机观测幅宽800公里。\n
宽幅相机（WFV）除了常见的蓝/绿/红/近红外四个波段，还增加了能够有效反映作物特有光谱特性的“红边”波段，以及一个紫外波段，一共8个波段，也被称为精准农业观测的高分卫星。\n

Gaofen 6 was officially put into operation on March 21, 2019, it is a low-orbit optical remote sensing satellite, with high resolution, wide coverage, high quality and efficient imaging, etc., configured with a 2-meter panchromatic/8-meter multispectral high-resolution camera (PMS), 16-meter multispectral medium-resolution wide-format camera (WFV), 2-meter panchromatic/8-meter multispectral camera The 2-meter panchromatic/8-meter multispectral camera has an observation width of 90 kilometers, and the 16-meter multispectral camera has an observation width of 800 kilometers.\n
Wide-format camera (WFV) in addition to the common blue/green/red/near-infrared four bands, but also added to effectively reflect the crop-specific spectral characteristics of the “red edge” band, as well as an ultraviolet band, a total of eight bands, is also known as precision agricultural observation of the high-frequency satellite.\n
This dataset collects the 2020 Gaofen-6 WFV data of Weihe River Basin, with 31 scenes selected throughout the year, which can fully cover the study area, and the products are original L1-level data without correction.
