How It Works – Step by Step
1. Load the Map
When the map loads, it centers on the continental U.S. (Zoom level 4). Users can zoom or scroll to browse any area.
2. Use the Jump-To Navigation
Select from a list of metro regions (e.g., New York, Chicago, Los Angeles) to instantly center the map on that area.
3. Find Nearby City Halls
Click “Near me” to allow geolocation and automatically pan the map to your current location.
4. Click to Select Locations
Click individual markers to highlight city/town hall buildings. Multiple selections are supported and tracked in a visible selection area.
5. Export Your Selection
Download selected city halls in:
- GeoJSON for GIS tools and web mapping
- KML for Google Earth and other 3D map tools
- GPX for use with GPS devices and navigation apps
Each download is dynamically generated with appropriate filenames based on the selected location(s).
6. Switch Map Views
Toggle between a street map (OpenStreetMap) and a high-resolution satellite map for context.
