Science Fiction Network10061th (Xu Mingyang) According to Science and Technology Daily, recently, researchers from the Geographic Landscape Remote Sensing Discipline Group of the Northeast Institute of Geography, Chinese Academy of Sciences developed a new remote sensing classification method, which completed the first time the national scale of foreign mangrove plant petal-free sea mulberry remote sensing extraction, and provided new ideas for the identification of plant community , which is difficult to obtain samples. Related research results were published in the Journal of ISPRS Photogrammetry and Remote Sensing, a journal of , , , and .
Remote sensing refers to the detection of the radiation and reflection characteristics of the electromagnetic wave of an object using a sensor or a remote sensor. Remote sensing has the ability to conduct dynamic observation and detection macroscopic, accurate and comprehensive. Remote sensing is one of the science and technology based on aerial photography technology developed in the early 1960s. After the advent of remote sensing technology, it was derived from North America to Europe and Asia, and then to South America and the African continent. The first land satellite launched by the United States in 1972 marked the arrival of the era of space remote sensing.
Remote sensing technology has the characteristics of a wide detection range, fast data collection, dynamic monitoring, rapid update, many means of obtaining information, large amount of information, comprehensive data obtained, and unlimited ground conditions; high economic and social benefits. The limitation of current remote sensing technology is that it can utilize relatively limited electromagnetic waves, and there are still many spectrum segment resources that need to be further developed.
At present, remote sensing technology has been widely used in many fields such as agriculture, forestry, oceans, geology, meteorology, military, and environmental protection. It can be seen from the detection of pests and diseases of farmland farmers to the assessment of geological disasters such as earthquakes and floods. In the future, with the development and mutual penetration of geographic information systems and global positioning system technologies, the application fields of remote sensing technology will become more and more extensive.
