Gaofen-1 (GF-1) satellite is the first star in the space-based system of the National High-Resolution Earth Observation System of Systems Major Special Project, whose main purpose is to break through the combination of high spatial resolution, multi-spectral and high temporal resolution of optical remote sensing technology, multi-payload image splicing and fusion technology, high-precision and high-stability attitude control technology, high-reliability low-orbit satellite technology with a life span of 5-8 years, high reliability, high data processing and applications, and other key technologies to promote the level of China's satellite engineering, improve the self-sufficiency of China's high-resolution data.
\nIn order to promote China's satellite engineering level and improve China's high-resolution data self-sufficiency rate, the company has developed a series of key technologies such as high-resolution data processing and application.\n
GF-1 (GF-1) WFV camera can obtain 16-meter multi-spectral color images (blue, green, red, near-infrared four bands).GF-1 satellite is loaded with WFV1, WFV2, WFV3 and WFV4 four WFV sensors, simultaneous imaging of up to 800 kilometers or so.\n
This dataset collects the 2020 GF-1 WFV data of Weihe River Basin, with 31 views selected throughout the year, which can completely cover the study area, and the products are raw L1-level data without correction processing.
