# Playground

> Interactive tool for exploring geospatial operations

The [Astral Playground](https://playground.astral.global) lets you experiment with geospatial operations before integrating them into your application.

## Modes

### Preview Mode

Test operations with instant visual feedback. Results are computed locally using Turf.js for a quick approximation.

<Note>
  Preview mode results may not exactly match verified results due to differences in how Turf.js and PostGIS perform geospatial computations, but they should be approximately the same.
</Note>

1. Select an operation from the dropdown
2. Drag markers or draw shapes on the map
3. See the preview result update in real-time
4. Click **Get Verified Result** to compute via PostGIS

### Policy Builder Mode

Create and publish attestations onchain.

1. Switch to **Policy Builder** tab
2. Connect your wallet
3. Select your target chain (Base Sepolia, Sepolia, Base, or Ethereum)
4. Enter a schema UID (defaults provided for numeric/boolean operations)
5. Configure your geometries
6. Click **Get Verified Result** to compute
7. Click **Publish to Chain** to submit the attestation via EAS

## Operations

| Operation      | What it does                         | Inputs                |
| -------------- | ------------------------------------ | --------------------- |
| **Distance**   | Meters between two points            | 2 points              |
| **Within**     | Is point A within radius of point B? | 2 points + radius (m) |
| **Contains**   | Is the point inside the polygon?     | polygon + point       |
| **Intersects** | Do geometries overlap?               | 2 geometries          |
| **Area**       | Square meters of a polygon           | polygon               |
| **Length**     | Meters of a line                     | linestring            |

## Working with the Map

**Points** — Drag markers directly on the map.

**Polygons & Lines** — Enable **map editing** to use drawing tools:

* Click the polygon/line tool in the top-left
* Click to place vertices
* Double-click to finish
* Click vertices to edit, drag to move

## GeoJSON Editor

The **GeoJSON** tab lets you paste or edit geometries directly:

```json theme={null}
{
  "type": "Point",
  "coordinates": [-122.4194, 37.7749]
}
```

Supported types: `Point`, `Polygon`, `LineString`.

## Code Snippets

The **SDK** and **cURL** tabs show integration code that updates as you configure your operation. Copy these directly into your project.
