Description

technical field [0001] The invention relates to the field of remote sensing information processing, in particular to a system for realizing dynamic release of satellite remote sensing data special application products by using computer network and distributed computing technology. Background technique [0002] Remote sensing information technology is playing an increasingly important role in the current society. As an emerging technology developed with the advancement of space technology in recent decades, it is a means to perceive and obtain information on the earth and its outer space macroscopically and remotely. It is widely used in many fields such as space exploration, environmental monitoring, resource exploration, weather forecasting, urban and land development planning, natural disaster dynamic monitoring, crop yield estimation, etc., and is creating huge economic and social benefits for all sectors of society. [0003] One of the characteristics of the development...

Problems solved by technology

[0005] Due to my country's vast territory and complex climate conditions, it is difficult for the existing communication equipment to transmit the HRPT polar-orbiting meteorological satellite data with a large amount of information to the user unit in time, prompting many meteorological, water conservancy, civil aviation, forestry, military and other departments to independently establish HRPT polar-orbiting meteorological satellite data receiving and utilization station to obtain satellite remote sensing information urgently needed by the department

However, this method can only satisfy users with certain economic and technical capabilities at present. For ordinary researchers and even ordinary public users, it is still difficult for polar-orbiting meteorological satellite data receiving and utilization stations to meet their requirements for remote sensing information products. need
