WebGPU-based high-performance map and globe visualization library.

MapGPU is distributed as a single npm package built with TypeScript, WGSL, and Rust/WebAssembly. Alongside the unified top-level API, it provides subpath entry points for core, layers, render, adapters, analysis, widgets, tools, terrain, tiles3d, react, milsymbol, testing, and wasm.

• WebGPU-accelerated 2D map and 3D globe rendering
• GeoJSON, raster tile, vector tile, WMS, imagery, and custom layer support
• Terrain, hillshade, and elevation workflows with DTED and Terrain RGB
• 3D Tiles, glTF/GLB models, and extrusion-based 3D scenes
• WMS, WFS, OGC API Features, and OGC API Maps adapters
• Drawing, measurement, vertex editing, and snapping tools
• Line of sight, buffer, elevation query, and route sampling analysis
• Framework-agnostic widgets and React components
• MIL-STD symbology integration
• Rust/WASM helpers for performance-critical workloads

pnpm add mapgpu

If you are using React, react and react-dom are also required as peer dependencies.

MapGPU is now published as a single package instead of multiple npm packages. Modules are consumed through subpath exports:

import { MapView, GeoJSONLayer, RasterTileLayer } from 'mapgpu';

const view = new MapView({
  container: 'map',
  center: [29.0, 41.0],
  zoom: 8,
});

view.map.add(
  new RasterTileLayer({
    urlTemplate: 'https://tile.openstreetmap.org/{z}/{x}/{y}.png',
  }),
);

view.map.add(
  new GeoJSONLayer({
    data: {
      type: 'FeatureCollection',
      features: [],
    },
  }),
);

import { MapView } from 'mapgpu/core';
import { GeoJSONLayer, RasterTileLayer } from 'mapgpu/layers';
import { WmsAdapter } from 'mapgpu/adapters';
import { LosAnalysis } from 'mapgpu/analysis';

import { MapView, RasterTileLayer, ScaleBar } from 'mapgpu/react';

export function App() {
  return (
    <MapView center={[29.0, 41.0]} zoom={8}>
      <RasterTileLayer urlTemplate="https://tile.openstreetmap.org/{z}/{x}/{y}.png" />
      <ScaleBar />
    </MapView>
  );
}

Requirements:

• Node.js 20+
• pnpm 10+
• Rust toolchain and wasm-pack if you are building the WASM package
