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.
In 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.
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.
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.
Data are available for download from the China Resource Satellite Application Center (CRASAC) at http://36.112.130.153:7777/DSSPlatform/gotocenterpage.html.
Data are at the raw L1 level and have not been otherwise manually processed.
This data comes from the website of the Land Observing Satellite Data Service Platform (LOSDSP), and is downloaded with good quality by screening the data with less than 10% cloud cover and quality level ≥ 8 (the highest level is 9).
