This application takes a set of points and a set of polygons and performs a spatial join. Points will be tagged with the properties of the polygon they are inside of.

This is useful for associating location lists with sales territories, work zones, or canvassing turfs.

1. Load a polygon file (GeoJSON) or draw polygons using the buttons on the toolbar.
2. Load a point file (GeoJSON or CSV).
3. Click the Tag Points button.
4. Click the dropdown to download tagged points.

How it works:

• 100% client-side processing (nothing uploaded to server).
• Local files are displayed on a Leaflet map using the FileReader Web API.
• The Turf.js geospatial library tag module is used to perform the spatial join.
