Data Sources/Dynamic World

Dynamic World

Near real-time 10m global land cover from Google and WRI, updated with every new Sentinel-2 image.

Urban Planning

Plan urban development, zoning, and infrastructure improvements using land cover, demographic, and transportation data.

Environmental Monitoring

Track environmental changes including deforestation, pollution levels, and ecosystem health using Earth observation data.

Agriculture & Land Use

Monitor crop health, soil conditions, and land use changes for precision agriculture and sustainable land management.

Dynamic World represents a fundamentally different approach to land cover mapping. Where traditional products like ESA WorldCover or NLCD produce a single validated map per year, Dynamic World generates a new classification with every Sentinel-2 overpass — giving you a near-continuous record of how the land surface is changing, not just what it looked like at one point in time.

Developed by Google and the World Resources Institute using deep learning, it trades thematic depth for temporal density: fewer classes than most alternatives, but the ability to detect deforestation, flooding, urban expansion, and crop cycles within days rather than waiting for an annual release.

This temporal resolution opens up workflows that static land cover maps simply cannot support. You can track flood extent as water probability spikes across a region, monitor post-fire recovery week by week, or compare planting and harvest patterns across growing seasons. The probability-based output also means you're not locked into a single classification — you can set custom thresholds, blend classes, or build composites tuned to your specific analysis.

For GIS analysts working on environmental monitoring, disaster response, or agricultural intelligence, Dynamic World turns land cover from a static reference layer into a continuously updating signal.

Frequently Asked Questions

Dynamic World produces a new land cover map with every Sentinel-2 overpass (every 2–5 days), while ESA WorldCover provides annually validated maps. Dynamic World outputs probability scores for 9 classes; WorldCover assigns a single class from 11 categories.

The archive begins in June 2015, when Sentinel-2 started collecting data, and continues to the present with new images added automatically.

Yes. Dynamic World is completely free for unrestricted use. Access it through the web app at dynamicworld.app, Google Earth Engine, or Google Cloud Storage.

Each image is an independent classification of a single Sentinel-2 scene, including cloud-affected pixels. Creating temporal composites (monthly or seasonal) produces much cleaner land cover maps by averaging out noise.

Dynamic World classifies into 9 classes — water, trees, grass, flooded vegetation, crops, shrub and scrub, built area, bare ground, and snow/ice. Each pixel receives probability scores for all classes rather than a single hard classification.
