Test Data Generator

Generate random Point or Polygon GeoJSON features within a bounding box.

How to use

Paste an area (or use the example) — random features are generated inside its bounding box.
Pick Point or Polygon and how many features to generate.

Useful for fixtures/test data — never for anything meant to represent real places.

Test Data Generation Coverage

Generates random Point or Polygon GeoJSON features, in a chosen count, within a bounding box you paste or draw.

Meant for seeding fixtures and demos — not for anything meant to represent a real place.

Frequently asked questions

Are the generated coordinates meaningful real-world locations?

No — they're uniformly random within the bounding box you provide.

Can I control how many features are generated?

Yes — you set both the feature type and count before generating.
