| This tutorial demonstrates how to efficiently analyze large geospatial datasets directly in your browser without downloading entire files. We'll use DuckDB-WASM and Observable JS to perform fast, memory-efficient analysis and create interactive visualizations. | ||
|
|
||
| **Note**: This tutorial attempts to connect to the live iSamples dataset (~300MB, 6+ million records). If CORS restrictions prevent access to the remote file, it automatically falls back to a representative demo dataset that demonstrates the same analytical techniques. |
| - **In-Browser Analytics**: Full analytical database running in JavaScript | ||
| - **Interactive Visualization**: Real-time exploration with Observable Plot | ||
|
|
||
| This approach enables **big data analysis in any browser** and makes large-scale geospatial analysis universally accessible! 🌍 |
