and atmosphere, along with a comprehensive operation and management model integrating reception, processing, distribution and sharing. According to the technical characteristics of different loads and user needs, we have developed remote sensing
applications in different fields such as land, ocean and atmosphere. These systems have helped in gaining advantages of high temporal, spatial and spectral resolution.
What is the position and core business of China Siwei Surveying & Mapping Technology Corporation (China Siwei) in the country’s earth observation system? China Siwei manages the country’s land observation satellite image data resource. This includes formulation and implementation of observation planning, data receiving and processing, data distribution and sharing. The spatial resolution of our satellites ranges from 0.5 m to 30 m that corresponds with high, medium and low scales. Spectral bands range from visible light, infrared to microwave, and spectral resolution ranges from multispectral to hyperspectral. GF-4 is the only geostationary orbit earth observation satellite in the world in terms of time resolution. SuperView-1 is
