What are some internal and external errors regarding remote sensing data?
a. Internal errors in remote sensing data may include radiometric and geometric distortions caused by sensor characteristics, atmospheric conditions, or terrain variations.
b. External errors in remote sensing data can arise from inaccuracies in ground truth data used for calibration and validation, as well as errors in processing algorithms and the generation of ancillary data.
c. Internal errors in remote sensing data may also stem from sensor malfunctions, calibration drift, and degradation in sensor performance over time.
d. External errors in remote sensing data might also result from human error in data collection, processing, and interpretation, as well as errors introduced by changes in land use and environmental conditions.
