WebAssembly Powered

The full DGGRID C++ library compiled to WASM — no server required. Runs in any modern browser or Node.js environment.

Multiple Grid Topologies

Supports HEXAGON, TRIANGLE, SQUARE, and DIAMOND topologies with ISEA and FULLER projections at any resolution.

Multi-Aperture Grids

Configure grids with mixed aperture sequences (e.g., "434747") for flexible grid refinement strategies and custom analysis needs.

GeoJSON Ready

Convert coordinates to DGGS cell IDs and back, or export entire grid regions directly as GeoJSON FeatureCollections for use with mapping libraries.
