I need to put together the cross-station logistics-overlap maps for the Antarctic Treaty consultative meeting next month. Each Antarctic research station has a notional 200 km operational radius. Please pull stations from Overture south of -60 latitude, along with the Antarctic landmass and water features.
For the first output I need the land-clipped station zones grouped into coalitions wherever they overlap. Each coalition gets an integer `coalition` id, and that column has to take more than one distinct value across the dataset. Every feature needs `station_id` and `station_name` as well. For the second output I need the over-water portion of each station's zone, attributed with the water features it intersects. Each row in that file must carry `station_id`, `station_name`, `water_id`, `water_name`, `water_subtype`, and a `water_source` column whose values are the literal Overture theme names `base.water` or `base.bathymetry`.
Please write both as GeoParquet in an appropriate projected coordinate system for Antarctica, with MultiPolygon geometry: `station_spheres.geoparquet` for the land-clipped coalition polygons, and `station_water_overlap.geoparquet` for the per-station over-water intersections with the water attribution described above.
