Annual plastic greenhouse classification maps for Northeast China from 2019 to 2025

This dataset provides annual 10-m plastic greenhouse (PG) classification maps for Northeast China from 2019 to 2025, together with reference samples and the study-area boundary used in the analysis. The annual PG maps were produced as binary raster datasets, where a value of 1 indicates plastic greenhouse pixels and a value of 0 indicates non-greenhouse areas. The raster data are provided in GeoTIFF format and projected in WGS 1984 Web Mercator Auxiliary Sphere (EPSG:3857). The dataset includes: (1) annual PG raster maps for Northeast China from 2019 to 2025; (2) reference sample data used for accuracy assessment and/or model evaluation; (3) the boundary file of Northeast China; and (4) a README file describing the dataset structure, raster value definitions, projection information, and basic usage notes. This dataset can be used for spatial analysis of plastic greenhouse distribution, interannual change detection, agricultural land-use studies, and further research on greenhouse expansion and regional agricultural intensification in Northeast China.
