What Contour Does
Contour turns natural language into geospatial workflows and maps.
It sits between data sources and visual outputs, handling everything in between.
How It Works
Contour makes spatial analysis repeatable, visual, and easy to reason about.
Natural Language First
With Contour, you don't write SQL or GIS scripts.
You describe what you want to see, and Contour builds and runs the workflow.
Data, Without Friction
Contour includes commonly used U.S. geospatial datasets out of the box, so you can start mapping immediately.
- •U.S. Census data (demographics, housing, income)
- •Major municipal datasets across U.S. cities (parcels, zoning, land use, streets, boundaries)
- •OpenStreetMap
- •Overture Maps
- •Other widely used public geospatial sources
You can also connect private or vendor datasets when needed. Contour does not require you to manually store, clean, or manage datasets.
Modular System
Contour is modular by design.
Agents
Interpret natural language requests
Workflows
Define spatial logic and reuse
Databases
Execute spatial operations
Renderers
Produce maps and artifacts
These components work together as a single system.
MCP and More
Contour exposes its capabilities through MCP so AI systems can generate maps directly.
MCP is the interface. The value is the workflow and the map that comes out.
Open Source
Contour is open source at its core. The system is designed to be inspectable, extensible, and self-hosted.
About
Contour is built by a small team focused on making maps easier to create and easier to trust.
We believe spatial tools should be simple, composable, and boring to maintain.
