Geotagged Layers
Weather, history, culture and commerce, each pinned to a coordinate rather than a page — explore data the way the ground actually holds it.
A survey instrument for the open web
Discover the world,
layer by layer.
GeoPher plots places, people and the record of time against one another — pulled live from the open Piperpal Location API, rendered in your browser, kept on your device.
Field survey
Query the map in real coordinates.
Enter a place, or take a bearing from where you're standing. GeoPher reads and writes against Piperpal's open location index — glat, glon, service, and radius, exactly as the instrument expects.
No bearing taken yet.
Nearby locations returned by the API will appear here, named and distanced from your query point.
Contribute a location to Piperpal
Four layers, one map.
Temporal Navigation
Scroll a place through its own past, present and projected future. Borders move; the coordinate doesn't.
Open APIs
Built directly on Piperpal's pull and push endpoints — plain HTTP, plain JSON, no proprietary map lock-in.
Privacy First
Your bearing is taken locally and never leaves your device unless you choose to push it. Encrypted by design, owned by you.
Surveyed by its users, not a corporation.
GeoPher is free software, built in the open alongside the GNU Photo and GNOME ecosystems. Fork it, self-host it, or point it at your own Piperpal-compatible index.
