Ephemeros for

Urban Growth

Watch neighbourhoods and skylines rise, one aligned photo at a time.

Explore the map

Pick a fixed viewpoint

A “spot” is a documented frame — coordinates, compass heading and tilt — that anyone can find again.

Line up with the ghost

The previous photo floats over your camera so every capture matches the original framing exactly.

Watch change unfold

Aligned photos become a timelapse — and an open, research-grade record of how the place changes.

Cities change faster than memory. A vacant lot becomes a tower crane, the crane becomes a skyline, and within a few years nobody quite remembers what stood there before.

Ephemeros gives a neighbourhood a shared memory. Pick a viewpoint — a bridge, a rooftop terrace, a street corner — and it becomes a spot: a fixed frame that anyone with the app can re-photograph, guided by a ghost overlay until the new photo lines up exactly with the first. Every aligned capture joins the spot's timelapse.

Why re-photography beats a photo archive

Same frame, every time. The in-app compass, tilt and ghost guides mean photos align pixel-for-pixel — so change is what moves, not the camera.
Many hands. You don't have to visit weekly for years; passers-by, commuters and other members keep the series alive.
A timelapse, not a folder. Each spot renders its photo series into an animation you can watch, share and embed.

Who uses this

Urban planners documenting densification, journalists tracking a development boom, community groups recording how their high street evolves, and photographers who simply love watching a city grow.

Start a spot outside your window today — in five years you'll be glad you did.
