This is OSINT challenge. One of the first steps as an action, could be checking metadata of this file.
You can make this in many ways, ie.: with the Exiftool or https://exifinfo.org/
We’re lucky! Data not erased:

GPS coordinates are a strong ‘handle’ for us.
To convert the given GPS coordinates to a format that can be used with Google Maps and similar services, you need to convert the degrees, minutes, and seconds (DMS) format to decimal degrees (DD). Here’s how you can do it:
Given Coordinates Latitude: 38 degrees 9' 15.95" S Longitude: 145 degrees 6' 29.69" E Conversion Formula The formula to convert DMS to DD is:
Latitude Conversion Degrees: 38 Minutes: 9 Seconds: 15.95
Since the latitude is South, it will be negative:
Longitude Conversion Degrees: 145 Minutes: 6 Seconds: 29.69
Since the longitude is East, it will be positive:
Final Coordinates for Google Maps Latitude: -38.15443056 Longitude: 145.10824722

Taking into account the perspective, it looks very promising!
The title is a hint to get proper name of this structure (keyword: ramp).
