Exploration of Geographic Environment Construction and Target Support Technology with Remote Sensing Big Data
Geographic environment construction and target assurance play an important role in security policy development,emergency response,homeland protection,disaster monitoring and other events.With the rapid development of air and space sensors such as satellites,drones,and ground sensor networks,remote sensing big data is becoming an important data source for geographic construction and target protection.Focused on the development status of remote sensing big data and starting from the acquisition technology of remote sensing big data,the key technologies are explored,such as global high-precision positioning and mapping of satellite remote sensing,construction of three-dimensional geographic environment of air and space remote sensing in key areas,interpretation of complete elements of remote sensing images,and retrieval of remote sensing targets.According to the practice of remote sensing big data in different scenarios,some typical cases of remote sensing big data are also briefly introduced,such as emergency response,natural disaster monitoring and assessment,etc.Finally,the application prospects of remote sensing big data are summarized and outlooked in the context of the current development and strategy of society.
