## What it is

LOCUS is a free, no-login web app that turns free-form addresses into structured place intelligence:

- Country  
- State / region  
- County  
- Locality / city  
- Postal code  
- Feature type  
- Data source  
- WGS 84 latitude & longitude  

It then plots the result on an interactive map. You can save locations in the browser and inspect them on a 3D globe.

## Why it exists

People need a fast way to resolve messy real-world addresses (including imperfect formatting) into administrative fields and coordinates without signing up for an API key.

## How geocoding works

LOCUS runs entirely in the browser and queries public providers in order:

1. **ArcGIS World Geocoder** — streets + suggest  
2. **US Census Geocoder** — strong US house-level + county  
3. **Nominatim (OpenStreetMap)** — global  
4. **Photon** — autocomplete / fallback  

The map uses **MapLibre GL** with **OpenFreeMap** tiles. The globe uses **globe.gl**.

## Privacy

- Saved places stay in **localStorage** on your device  
- There is no LOCUS server database of your addresses  
- Geocode requests go from your browser to the public providers above
