MapSpace LSG 2026: Oceania 11-Class Land Use

Dataset Details

This dataset contains POI-based land-use estimates for LandScan Global grid cells in Oceania. It was generated and is shared by the Geospatial Science and Engineering Division at Oak Ridge National Laboratory.

• Curated by: Geospatial Science and Engineering Division, Oak Ridge National Laboratory
• Version: v1
• License: CC BY 4.0
• Geographic coverage: Oceania
• Spatial grid: 30 arc seconds (1/120 degree)
• CRS: EPSG:4326
• Format: GeoParquet, one country or territory per file
• Files: 28
• Rows: 11,159,226
• Contact: mapspace@ornl.gov

Each row represents one grid cell and contains probabilities for 11 land-use classes, an argmax label, prediction diagnostics, and the cell geometry. These values are model outputs or a documented no-feature fallback; they are not ground-truth land-use observations.

This is an 11-class, 30-arc-second product. It is distinct from the earlier three-class MapSpace dataset cited under Related Work.

Dataset Structure

The repository root contains 28 GeoParquet files. The current schema is:

Column	Type	Description
id	string	Grid-cell identifier.
global_row	int64	Global LandScan grid row.
global_col	int64	Global LandScan grid column.
ls23_country	string	Country or territory attribute inherited from the LandScan grid.
geom	binary	Polygon or MultiPolygon encoded as GeoArrow/GeoParquet WKB in EPSG:4326.
agricultural	float32	Agricultural probability.
commercial	float32	Commercial probability.
education	float32	Education probability.
industrial	float32	Industrial probability.
institutional	float32	Institutional probability.
military	float32	Military probability.
open_space	float32	Open-space probability.
recreation	float32	Recreation probability.
residential	float32	Residential probability.
retail	float32	Retail probability.
transportation	float32	Transportation probability.
landuse_label	string	Class with the largest probability.
landuse_probability	float32	Largest class probability.
confidence_level	string	Probability bin: high, medium, low, or mixed.
prediction_entropy	float32	Natural-log entropy, -sum(p * ln(p)).
label_source	string	model_prediction or no_feature_fallback.

Class columns appear in the order shown above. Exact probability ties are resolved by that order.

Confidence levels are assigned from landuse_probability as follows:

• high: at least 0.70
• medium: at least 0.50 and below 0.70
• low: at least 0.35 and below 0.50
• mixed: below 0.35

Label provenance

label_source	Rows	Percent	Meaning
model_prediction	1,194,363	10.703%	Probabilities produced by the land-use model.
no_feature_fallback	9,964,863	89.297%	No POI/tag feature was available; release construction assigns a one-hot open_space vector.

no_feature_fallback does not mean that the model or an independent observation established that the cell is open space. Filter on label_source == "model_prediction" when analyses require model-derived labels only.

Source Data and Method

Inputs include OpenStreetMap and PlanetSense Program POI/feature tags joined to the LandScan Global grid. Training labels are derived from OpenStreetMap land-use, POI, and natural-feature polygons mapped to the 11 classes. The pipeline uses TF-IDF features and XGBoost multiclass probability models. Models are fitted by source area; areas without sufficient training data may use a donor model.

Exact snapshot dates for OpenStreetMap, PlanetSense, and LandScan inputs are not supplied in this release.

Uses

Potential direct uses include urban planning, transportation planning, population modeling, and disaster-risk assessment. Users should validate fitness for their geography and application before operational use.

This dataset should not be treated as parcel-level land use, legal zoning, surveyed ground truth, or a substitute for local authoritative data.

Bias, Risks, and Limitations

• OpenStreetMap-derived training labels are weak labels and vary in completeness, positional accuracy, tagging practice, and class balance by geography.
• Model performance can therefore vary across countries, regions, and classes. Sparse areas may depend on geographically transferred donor models.
• POI and feature coverage is uneven. A large share of rows may use no_feature_fallback; these rows require separate interpretation.
• The 30-arc-second grid is angular, not equal-area. East-west cell width decreases with latitude.
• Independent input snapshots can create temporal mismatch.
• A consolidated accuracy estimate for this regional release is not provided. Do not infer accuracy from landuse_probability or confidence_level alone.
