GPS-Based Unity Environment Creation

I'm looking for a skilled Unity developer to create a real-life environment using GPS data, potentially using Mapbox or a similar service.

I need this hiking trail recreated 100% real life.

I have the raw trail data info export file. I have csv / json other file types.
