Atlas Open-Data Hub
Atlas turns a government's map services into a living atlas: hover to preview any layer instantly, pin layers to compose your own map, and draw an area to see everything that covers it. Instead of a directory that hands you a zip file, the map is the page — visitors and staff leave with a working, ArcGIS-compatible map, not a download. It's the open-data portal, catalog and public map in one, self-hosted and sovereign, and every dataset stays consumable by ArcGIS Pro, QGIS and MapLibre unchanged.
Runs on Strata, or on your existing Esri services. Opens in a new tab.
How the app works — the walkthrough
A short, self-contained deck that walks through what the app does. Use the arrow keys inside it, or open it full-screen.
Cloned a recipe, opened it in Claude — the app built itself
This app — and six others — were generated in a single run from recipes handed to Claude. Clone the recipe from our GitHub repository, open it in Claude, and start building advanced, Esri-compatible web mapping applications immediately, on your own data.
Serve your data. Then talk to it.
Strata serves your spatial data over the ArcGIS REST protocol, then lets anyone explore it in plain language — on-prem and sovereign, at a fraction of Enterprise cost. Keep your Esri licenses.
