Austria

Benchmark chips for Austria cut from the harmonized field boundary collection for Austria (edition 2025).

What is in this collection

This collection holds 11,242 chips and 656,619 field polygons. Each chip is a square STAC item carrying the label masks rasterized from the field boundaries that fall inside it.

Chips per benchmark split:

How much of a chip is mapped field, as a distribution over the chips (field_coverage_pct):

Every chip carries these label rasters as STAC assets: instance_mask, semantic_2class_mask, semantic_3class_mask.

Crops

Crops are harmonized to the EuroCrops HCAT taxonomy. The classes covering most of this collection:

Styles

Ready-made map styles ship with the collection:

• Chips by split (the default view): chips coloured by their train / val / test assignment.
• Field coverage: chips shaded light to dark by the share of their area covered by fields.
• Dominant crop per chip: chips coloured by the crop covering most of their field area.
• Crops: fields coloured by their harmonized crop (EuroCrops HCAT).
• Field outlines: every field in one colour, for reading the boundaries themselves.

Provenance

• Agrarmarkt Austria: producer, licensor
• Fields of the World: processor
• License: CC-BY-4.0
• Derived from Source field boundary collection
• Splits assigned with the block3x3 strategy, random seed 42
• Masks rasterized at 10 m per pixel

Suggested uses

• Training and evaluating field boundary delineation models on the pre-assigned, reproducible split.
• Comparing model performance across regions by filtering chips on id, which carries the grid cell each chip was cut from.
• Sampling field polygons for crop-type work, using the harmonized HCAT codes.

Limitations

• Masks are derived from field boundaries declared for a given year; parcels that changed shape, were subdivided or merged after that declaration are not reflected.
• Chips on the border of the source dataset may be only partly covered by field boundaries, and empty area there means unmapped, not fieldless.

Access

items.parquet mirrors every chip item, so the whole collection can be queried without walking the catalog:
