Here, an object- and topology-based analysis (OTBA) method, which considers spectral-spatial features and the topological relationship between paddy fields and their enclosed ditches, was proposed to identify  ...  The rice-crayfish field (i.e., RCF), a newly emerging rice cultivation pattern, has greatly expanded in China in the last decade due to its significant ecological and economic benefits.  ...  Acknowledgments: We sincerely thank the editors and four anonymous reviewers for their detailed and helpful comments which greatly improved this article.  ...
