Obtain LBS big data and city vitality

If it is helpful to your problem, hope to adopt!

LBS(Location-based Services) data can be obtained from multiple sources, depending on the data type and precision you need.

You can use social media platforms such as Twitter or Instagram to get photos and location information about users in the park.
You can also use mobile apps and software, such as Moovit or Citymapper, to get traffic flow data.
If you need more precise data, you might consider using a mapping service provider, such as Google Maps or OpenStreetMap, to get park location and pedestrian data.
