Hungary Crop Fields (GeoParquet, EUCROPMAP 2022)

Dataset Summary

Vector polygons of crop fields in Hungary derived from EUCROPMAP 2022 and packaged as a compact GeoParquet.
Each feature has a stable field_id, crop field_type (sunflower or rapeseed), the ADM1 region (ASCII slug), and the polygon geometry in EPSG:4326. Convenience bounding-box columns (minx, miny, maxx, maxy) are included to enable fast spatial indexing without loading full geometries.

What this is: geometry for fields (one record per field).
What this is not: time series. Pair it with your raster-to-point or gridded time-series (e.g., ERA5-Land, Sentinel-2 aggregates) and assign per-date features to fields via a spatial join.
