# arcgis-geometry-calculations
[This tool](https://hhkaos.github.io/arcgis-geometry-calculations/) allow you to easily grab the geometry resulting from a spatial geometry calculation (buffers, intersections, unions, ...). It was made to provide an additional1 way to spatial queries within ArcGIS feature services as shown in the [following video](https://youtu.be/dkEt_dz8KZA).
> **(1)** Feature services have a ["distance" parameter](https://developers.arcgis.com/documentation/mapping-apis-and-services/data-hosting/services/feature-service/#distance) that allow you request the service to make the spatial intersect with the buffer on the backend in your behalf.
## About the demo
The service used on that video was [Current Weather and Wind Station Data](https://hhkaos2.maps.arcgis.com/home/item.html?id=cb1886ff0a9d4156ba4d2fadd7e8a139) that contains +5800 weather stations.
**Service url**: [Current Weather and Wind Station Data service URL](https://services9.arcgis.com/RHVPKKiFTONKtxq3/ArcGIS/rest/services/NOAA_METAR_current_wind_speed_direction_v1/FeatureServer/0).
The response of the query shown on the video was:
```json
