| # 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. |
