Explore U.S. State Supreme Court Locations on an Interactive Map
Discover the exact locations of state supreme court buildings and judicial facilities with this interactive map. Powered by authoritative USGS National Map data, this tool helps legal professionals, researchers, educators, and curious citizens explore the geography of the highest courts in the nation.
Explore state supreme court buildings and judicial facilities across the United States from the USGS National Map Structures database.
What This Map Shows and Why It Matters
The map lets you:
- Visualize state supreme court buildings using live data from the U.S. Geological Survey’s Structures dataset.
- Navigate with ease through “Jump to…” presets (Continental US, New York, Los Angeles, Chicago, Houston, Phoenix, Denver, Seattle).
- Locate nearby courts with the “Near me” button using your browser’s geolocation.
- Select multiple courts by clicking markers; each selection highlights clearly.
- Export your selections in GeoJSON, KML, or GPX formats for GIS, mapping tools, and GPS devices.
- Switch between street view and satellite imagery.
This makes the map ideal for:
- Reference and citation in legal documents
- GIS and spatial analysis workflows
- Education on civic institutions
- Planning visits or visual mapping of judicial infrastructure
How It Works – Step by Step
1. Load and view the map
By default, the map centers on the U.S. at a wide view (zoom level 4). Scroll or zoom in to explore court locations across states.
2. Jump to a region
Use the dropdown labeled “Jump to…” to instantly pan to major metro areas or zoom out to view all state supreme courts.
3. Center on your location
Click the “Near me” button (allow browser location access) to navigate quickly to your surroundings and nearby courts.
4. Select court markers
Click any court marker to select it. Selected courts highlight and remain until you clear the selection. The status panel indicates either the court’s name (for one selection) or the number of courts selected.
5. Download coordinates
After selecting, choose GeoJSON, KML, or GPX to download files compatible with GIS tools, mapping programs, or GPS devices.
6. Switch map views
Open the layers control (⚖ icon) to toggle between OpenStreetMap and high-resolution satellite imagery.
