# OpenLayers Data

This repository includes data used for examples hosted at openlayers.org.  The contents of the `docs` directory in this repo will be published at http://openlayers.org/data/.

When adding new GeoJSON data, use the `scripts/tidy.js` script to tidy up the data first.

For example, to remove all the properties, ensure that polygon rings are properly oriented, and to limit coordinate precision:

```bash
npm install
node scripts/tidy.js --input path/to/downloaded/input.json --properties '' > docs/vector/output.json
```
