You’ll learn how to integrate these libraries, build performant and interactive map-based dashboards, and explore tips for handling dynamic data, custom layers, and user interactions in a modern React environment.
The second half will feature a data scientist who will demystify the process behind the maps. They’ll explain how vector tiles are generated, optimized, and served and walk through real-world examples of geospatial data processing pipelines. You’ll gain a clear understanding of how the backend work empowers your front-end visualizations.
