NATIONAL SATELLITE IMAGE COVERAGE USING OVERALL PLANNING TECHNIQUE

Remote sensing image is one of the most important data source for geographic information system. In 2015, China has conducted a standard point approval mission to update and improve the results of the first geographic conditions census. Majority of the geographic information was extracted from optical remote sensing image of satellite. An overall planning technique was introduced to optimize the usage of all available satellite image resources. It has shown that, only 65% of available satellite images were used to get a maximum coverage for province-scale area, and more images are needed for larger mission areas. Also, a cloud-free coverage plan of available satellite images can be designed using the overall planning technique. The overall planning technique has a great potential in designing an optimal image coverage plan over a certain area.
