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

Any data sourceCensus, municipal, OSM, Overture, private data
Contour
natural language → workflows
Maps and outputs

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.
