Sample answer:
Challenges Faced While Working with Remote Sensing Data in Astronomy:
-
Data Volume and Processing Requirements: Astronomical datasets are often vast, requiring specialized algorithms and extensive computational resources for processing. Handling and analyzing large volumes of data can be challenging, especially for real-time or time-series applications.
-
Data Quality and Calibration: Remote sensing data can be affected by various instrumental and environmental factors, leading to noise, artifacts, and uncertainties. Correcting for these distortions and calibrating data to ensure accuracy requires sophisticated techniques.
-
Noise and Background Subtraction: Astronomical images often contain significant background noise and unwanted signal, making it difficult to extract faint objects. Advanced image processing algorithms are needed to remove noise and enhance the signal-to-noise ratio.
-
Multiwavelength Data Fusion: Astronomy involves combining data from different wavelengths to obtain a more comprehensive view of celestial objects. Fusing multiwavelength datasets can be challenging due to differences in resolution, sensitivity, and calibration techniques.
-
Data Provenance and Traceability: It is crucial to track the origin … Read full answer
