Build maps, manage data, automate pipelines ā all in the open.
A free, open and highly extensible WebGIS platform. Bring your GIS data onto a 3D globe, style it, tell a story with it, and publish it ā no code required.
|
Creating and publishing databases. Model your geospatial content, keep it reviewed and versioned, and serve it straight to your apps through an API.
|
An ETL web tool to build and run automated workflows. Wire up nodes on a canvas to convert, validate and transform large geospatial datasets.
|
A highly extensible 3D map engine. A headless GIS core in Rust/WebAssembly with a tiered API ā declarative config at the top, your own shaders at the bottom.
|
Open data services that anything on the map can build on.
