Here are some pictures.
The flag format will be bcactf{ANS1_ANS2_ANS3}, where:
- ANS1 is the first word of the [what3words](https://what3words.com/) code of the
main Google Maps pin on the circled building in geolocation-1.jpg.
For example, if it was the Empire State Building (heave.wipes.clay),
ANS1 would be "heave".
- ANS2 is the second word of the what3words code of the
exact coordinates from the photosphere URL of geolocation-2.jpg.
- ANS3 is the third word of the what3words code of the
exact coordinates from the Street View URL of geolocation-3.png.

Suggested solutions:
1. Identify the extremely wide highway (Ontario Highway 401).
For example, searching for "18-lane highway" or even just
"wide highway near airport" can lead you towards the correct
location. The building is the Mississauga Harley-Davidson,
which has what3words ///beeline.tape.couch.

2. Careful manipulation of the image (such as by viewing it
in a program that can properly view 360-degree photos and
cropping) can yield something that Yandex Reverse Image Search
can recognize. Alternatively, search for something like
"white tram bridge europe" to find other images of the bridge.
The location is 48.5743659,7.8020683, ///colleague.fairy.helpers.

3. This is Malta (BNF Bank advertisement). Look for a bus stop
near a wide road (e.g. with https://osm-search.bellingcat.com/).
The location is 35.8765799, 14.4950154, ///face.discount.slacker.
