The modern spatial stack — compatible with ArcGIS®
Serve your geospatial data over the ArcGIS REST protocol with a lightweight server, and let anyone ask your maps questions in plain, natural language. Try both free on open data.
Works with ArcGIS Pro, the ArcGIS Maps SDK, QGIS, and MapLibre — no migration required.
Two products, one spatial platform
Use them together or on their own. Both speak the Esri stack your teams already know.
Strata Server
A lightweight server that publishes your GeoParquet / spatial data as ArcGIS-compatible Feature & Vector Tile services. Drop it into ArcGIS Pro, the JS SDK, QGIS, or MapLibre unchanged.
Strata GeoAI
A natural-language conversational GIS assistant. Ask your maps questions in plain language and get live maps, tables, and charts — with a deterministic command mode for no-hallucination operations, and an on-prem / local-LLM option.
Beyond software — data and expert services
Strata Atlas — data package
Boundaries, demographics, economy, base maps and more — curated data sold as a ready-to-use data package.
Implementation & integration
Deployment of Strata Server and Strata GeoAI, data onboarding, and custom integration with your systems.
Training & support
Onboarding, team enablement, and ongoing support to get the most from Strata.
Built to complement your ArcGIS investment
Drop-in compatible
Speaks FeatureServer & VectorTileServer — your existing ArcGIS clients connect unchanged.
Natural-language
Conversational GIS that understands plain, everyday language.
Sovereign by design
Run fully on-premises with a local model — your data never leaves the building.
Serve your data. Then talk to it.
Strata Server publishes your spatial data over the ArcGIS REST protocol, and Strata GeoAI lets anyone explore it in plain language — on your own or open global data.
