### 🛠 Model Purpose |
|
|
This model is part of the **[GeoAi](https://github.com/decision-labs/geoai.js)** javascript library. |
|
|
|
|
|
**GeoAi** enables geospatial AI inference **directly in the browser or Node.js** without requiring a heavy backend. |
|
|
|
|
|
**GeoAi** pipeline accepts **geospatial polygons** as input (in GeoJSON format) and outputs results as a **GeoJSON FeatureCollection**, ready for use with libraries like **Leaflet** and **Mapbox GL**. |
