Continuous Discontinuous Irrigated Areas in China Dataset (CDIA) (2000-2022)

The Continuous Discontinuous Irrigated Areas in China dataset (CDIA) provides information on irrigated areas in China from 2000 to 2022. This dataset was generated using a novel irrigated area sampling framework to accurately identify both continuous and discontinuous samples (i.e., pixels irregularly irrigated across different years). It provides annual IA maps over China using 1688 area-specific random forest models. with remotely sensed data (e.g., vegetation indices, climate factors, and terrain factor), and government censored data (GCD) as ancillary inputs.<b>Key Features</b>:Temporal Coverage: 2000-2022Spatial Resolution: 500 metersData Sources: Remotely sensed data, government censored data (GCD), and random forest modelSpatial Reference System: EPSG:4326 (WGS-1984)File Type: TIFF:<b>Data Description</b>:This dataset depicts the spatial distribution of irrigated areas in China from 2000 to 2022. It provides insights into the dynamics of irrigation practices across different regions of China. Users can explore the temporal and spatial patterns of irrigated areas and conduct analyses to understand IA changes over time<b>Usage</b>:Researchers and policymakers can use this dataset for various purposes, including:Monitoring temporal changes of irrigated areas over ChinaAssessing the effectiveness of irrigation management policiesUnderstanding the impact of climate change on irrigation practicesIntegrating irrigation data into land use planning and agricultural development strategiesConducting predictive modeling of irrigation demand or optimizing irrigation schedulingLicense:The CDIA dataset is made available under CC BY-NC 4.0 license.
