Two key advantages of using an orbiting remote sensing system are the ability to provide globally consistent observations and to collect data in areas inaccessible to ground-based instruments.
Here's a more detailed breakdown:
-
Globally Consistent Observations: Satellite-based remote sensing systems offer a unique vantage point for observing the Earth as a whole. This allows for the acquisition of data in a standardized and consistent manner across vast geographical areas. This consistency is vital for building comprehensive datasets and understanding global processes, such as climate change, deforestation, and ocean currents. Because the satellite sensors are calibrated and operate under consistent conditions, the data collected is directly comparable, regardless of location.
-
Access to Inaccessible Areas: Many regions of the Earth are difficult or impossible to access for ground-based measurements. These areas include dense rainforests, remote polar regions, vast oceans, and conflict zones. Orbiting remote sensing systems provide a means of gathering data in these locations, filling critical data gaps and enabling scientists to study these important ecosystems and environments. Without satellite remote sensing, monitoring and understanding these regions would be significantly more challenging, if not impossible.
These two advantages are crucial for a wide range of applications, from environmental monitoring and resource management to disaster response and national security. The ability to obtain consistent, global data and access remote regions makes orbiting remote sensing systems invaluable tools for understanding and managing our planet.
