Abstract In this paper, the technical procedures and data analysis in using Bayesian network to process airborne
data are described. The result shows that the Bayesian network method has three advantages. First, both the prior
probability and features are used to establish the probability estimation weighing relations shown in associated
probability chart; Second, the linkage of the directed acyclic graph (DAG) and classes can clearly show the
relations between independence vectors (bands) and classes; Third, according to the contribution degree of three
inputted bands quantitatively shown in associated probabilities for each class, the prior probability can be
revised. The study results suggest that Bayesian network is likely to become a new practical method for remote
sensing data processing.
