Exploring historical photographs integrated with modern maps

A developer created a tool that maps images using their metadata and includes an arrow indicating the direction each photo is facing, solving a challenge others have struggled with.

Why it matters: Automatically determining photo orientation enhances map-based image organization and user understanding.

The big picture: Image metadata has evolved, possibly containing more detailed information like camera orientation and direction.

The other side: Some users still manually set facing direction due to difficulty extracting this data from metadata.

Commenters say: Many are impressed by the automatic facing feature and are curious about the techniques or AI used to achieve it.
