Turn real map input into structured coordinates
The parser accepts direct latitude and longitude plus common Apple Maps, Google Maps, Amap, and Baidu links. It extracts a place name and coordinates from URLs, query parameters, or a bounded page response, then returns the source, confidence, original system, and warnings.
- Input length is bounded, and coordinates must stay within latitude ±90 and longitude ±180.
- Short links follow only a limited number of redirects; local, private-network, and cloud-metadata addresses are rejected.
- Unrecognized input returns a clear error instead of inventing a plausible location.
