osm-polygon-selection dataset
A curated set of OpenStreetMap polygons from 310
geographic units — sovereign countries plus sub-country regions
like Brazilian states, Chinese provinces, Indian zones, US states,
Canadian provinces, Japanese regions, and Indonesian islands —
classified by size bin (small / medium / large, area in
[0.1, 100] km²) and tagged by continent (Natural Earth admin0 lookup).
Size bins:
small — area in [0.1, 1) km² (10,000 m² to 1 km², roughly
100 m × 100 m… See the full description on the dataset page: https://huggingface.co/datasets/NoeFlandre/osm-polygon-selection.osm-polygon-wikidata-only

OSM Polygon Description Tag
OpenStreetMap polygons with a successfully extracted trimmed non-empty
description or
description:<suffix> tag, published as one GeoParquet file per regional PBF
extract. Every row retains the complete original tag map, full Polygon or
MultiPolygon geometry, WGS84 geodesic area, bounding box, and OSM provenance.

Shape Polygons Dataset
A synthetic dataset containing 70,000 images of various colored polygons (triangles to octagons) rendered on black backgrounds.
Dataset Description
This dataset consists of programmatically generated polygon images with full metadata about each shape's properties. It's designed for tasks such as:
Shape Classification: Classify polygons by number of vertices (3-8)
Regression Tasks: Predict shape properties (size, angle, position, color)
