Land Cover Mapping in Limited Labels Scenario: A Survey
This is a survey paper that synthesizes existing research for domain-specific applications in environmental monitoring, making it incremental in nature.
The paper surveys challenges in land cover mapping, such as limited training data and data heterogeneity, and reviews machine learning methods to address these issues, without presenting new experimental results.
Land cover mapping is essential for monitoring global environmental change and managing natural resources. Unfortunately, traditional classification models are plagued by limited training data available in existing land cover products and data heterogeneity over space and time. In this survey, we provide a structured and comprehensive overview of challenges in land cover mapping and machine learning methods used to address these problems. We also discuss the gaps and opportunities that exist for advancing research in this promising direction.
