MapSpace LSG 2026: Remote Territory 11-Class Land Use

Dataset Details

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

The Spratly Islands file is intentionally excluded from this release.

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 14 GeoParquet files. The current schema is:

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

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.
