Remote Sensing Satellites for Digital Earth

Abstract: The term remote sensing became common after 1962 and generally refers to nonintrusive Earth observation using electromagnetic waves from a platform some distance away from the object of the study. After more than five decades of development, humankind can now use different types of optical and microwave sensors to obtain large datasets with high precision and high resolution for the atmosphere, ocean, and land. The frequency of data acquisition ranges from once per month to once per minute, the spatial resolut… Show more

“…SAR is an active Earth observation system that can be installed on aircraft, satellites, spaceships and other flight platforms. It can observe the earth on all days and in all weather and it has a certain surface penetration ability [22][23][24]. SAR mainly records all kinds of backscatter responses produced by crop canopy biophysical structure.…”

“…Another shortcoming of the experiment is that only two data sources were compared, mainly as they are freely available compared to other sources that have finer ground sampling distance. In addition, useable remote sensing satellites with higher resolution (e.g., the China-Brazil Earth Resource Satellites, HJ−1A and HJ−1B environment and disaster reduction satellites, and high-definition Earth observation satellite GF−8), could be used for analyzing the cloud cover [63].…”

“…This is due to the possibility of unimpeded receipt of species information on objects and areas of interest, as well as the fact that the necessary information is obtained remotely. Also, the data obtained with the help of satellites and remote sensing systems on the territory of Donetsk and Luhansk regions and in Crimea are the only source of objective and operational information 2 . The information 1.…”
