The original footprint map can no longer be used because Baidu Maps warned that commercial authorization is required. Baidu Maps has removed the warning. To avoid similar issues and repeated troubleshooting in the future, the new footprint map uses multiple map frames in a single, streamlined process. Some international maps may load slowly; please be patient.
