# GIS Spatial Engineering You use this skill to generate the physical path of the marathon. ## Geographic Context (Built-in Data) You have access to a road network GeoJSON located at `assets/network.json`. Key features available in this network include: - **Landmarks**: Point features with `properties.name` (e.g., Mandalay Bay, Bellagio, Sphere, Las Vegas Sign, Allegiant Stadium, The Venetian, Michelob Ultra Arena, etc.). These landmarks are used automatically by `plan_marathon_route()` to build the route. - **Named Roads**: All 34 LineString features have `properties.name` (e.g., Las Vegas Boulevard, Las Vegas Freeway, Sahara Avenue, Flamingo Road, Rainbow Boulevard, Paradise Road, Sunset Road, Tropicana Avenue, Desert Inn Road, Eastern Avenue, Maryland Parkway, etc.). ## Algorithm The default algorithm is **zone-sweep**: the route starts at the Las Vegas Sign, goes northbound on the Strip past MGM Grand, sweeps through city zones (neighborhoods) using non-crossing geometry, and finishes near a prominent landmark (e.g., Michelob Ultra Arena). The algorithm handles all route geometry automatically — you do not need to select petals or manually sequence landmarks. ## Instructions 1. **Just call it**: `plan_marathon_route()` with no arguments produces a valid 26.2-mile zone-sweep route. Use `finish_landmark` and `seed` for variety. 2. **Precision**: The tool uses interpolation to guarantee exactly 26.2 miles. 3. **GeoJSON**: Input must be valid road network GeoJSON. ## Tools - `plan_marathon_route(finish_landmark: Optional[str] = None, seed: Optional[int] = None, geojson_data: Optional[str] = None)`: Generate the exact 26.2-mile path. - `finish_landmark`: Name of a landmark to finish near (e.g., `"Michelob Ultra Arena"`). - `seed`: Integer seed for route variety. Different seeds produce different routes. - `report_marathon_route(route_geojson: dict)`: Emit the final GeoJSON to the system registry. ### Decision-Making Guidance - For most requests, call `plan_marathon_route()` with default arguments. - Use `seed` to generate alternative routes when the user wants variety. - Use `finish_landmark` when the user specifies a preferred finishing area.
