Geo Picker is a lightweight VS Code extension that lets you choose a point on an interactive map and automatically inserts the corresponding latitude/longitude pair into the active editor.
Features
Open an interactive map panel beside the editor.
Click anywhere on the map to drop a marker.
Preview the expected coordinate output before insertion.
Use the Insert Coordinate button to write lat, lng at the original cursor location.
Choose between different formatting options: lat, lng, lng, lat, [lat, lng], [lng, lat], and {lat: x, lng: y}.
Choose the decimal precision (4-6).
Coordinate automatically copied to clipboard.
Accessible via the command palette or the editor context menu.
Requirements
None – the extension is written in TypeScript and loads Leaflet via CDN.
An internet connection is required to fetch OpenStreetMap tiles and Leaflet resources.
Usage
Open a text file and place the cursor where you want coordinates inserted.
Invoke the Add Coordinate command from the palette (Cmd+Shift+P ➜ Add Coordinate) or right-click in the editor and choose Add Coordinate.
A map panel opens side-by-side. Click a point on the map to select it.
Choose your preferred format (e.g., lat, lng, [lat, lng], {lat: x, lng: y}) and precision (4-6 decimal places).
Preview the Expected Output field to see exactly what will be inserted.
Press Insert Coordinate – the formatted coordinate is inserted at the cursor and copied to your clipboard.
You may open multiple maps simultaneously; each returns coordinates independently of the others.
Extension Settings
This extension does not contribute any user-configurable settings.
Known Issues
Map tiles require an active internet connection.
Only decimal‑degree coordinates are supported at the moment.
