Where is the photographer

Let say you have a picture with at least 5 identified points (e.g. summits) and that you want to determine from which location the picture has been taken, that's what this project is all about.

Run the unit tests:

uv run -m unittest discover .

Run the server, locally:

uv run uvicorn server:app --reload

Then open http://localhost:8000/index.html

Manually test the API:

curl -d '{"projections":[1.2, 3.4], "latlngs":[[1.3, 6.7], [5.4, 9.6]]}' -H "Content-Type: application/json" -X POST http://localhost:8000/locate/

Or with a data file:

curl -d "@data.json" -H "Content-Type: application/json" -X POST http://localhost:8000/locate/

Build the docker image:

docker build -t <user/repository> .

Run the docker image (the Google Maps API key is passed at runtime, never baked into the image):

docker run -p 8000:8000 -e GOOGLE_MAPS_API_KEY=your-key-here -d <user/repository>
