Understanding WebAssembly (WASM)
What is WebAssembly?
WebAssembly is a binary instruction format that enables execution at near-native speed inside web browsers. At CGGIS, we use WASM to execute intensive geospatial algorithms directly in clients' browsers, achieving performance competitive with traditional software.
Key Features
- 🚀 Near-native execution speed
- 🌐 Runs in all major browsers
- 🔒 Secure sandboxed environment
- 📦 Modular binary format
Our Implementation
CGgis.com uses custom WASM modules for:
- Accelerated raster analysis
- Real-time 3D terrain rendering
- Instant spatial joins
- Offline map generation
Real-World Applications
Real-Time Analytics
WASM accelerates spatial operations by over 20x compared to pure JavaScript, enabling instant analysis of petabyte-scale datasets.
Cross-Platform Delivery
Same WASM binaries run in desktop apps, web portals, and mobile devices - eliminating platform-specific code
Offline Capabilities
Mobile field operations now possible with WASM-powered offline analysis engines for 60+ spatial algorithms
Architecture & Integration
Our WASM Stack
- Rust-based modules for optimal C++ performance
- Emscripten toolchain optimization
- WASI system interfaces implementation
