# How to Reverse Geocode Coordinates with Copilot

Copilot reverse geocodes coordinates within your development workflow. Update location labels in data files, enrich test fixtures with realistic addresses from actual coordinates, and replace placeholder location strings across your project with properly resolved addresses.

## Setup

{"mcpServers":{"toolrouter":{"command":"npx","args":["-y","toolrouter-mcp"]}}}

## Steps

1. Add ToolRouter to Copilot MCP config
2. In Copilot Chat: "Reverse geocode these coordinates" and paste the lat/lng values
3. Copilot returns the address and structured location data
4. Ask: "Update the location labels in my data file with these addresses"

## Example Prompt

```
Reverse geocode the coordinates in my test fixtures and replace the placeholder addresses with real ones.
```

## Tips

- Useful for enriching test data and fixtures with realistic location information
- Copilot can update coordinate labels across multiple files in one session
