3. On-Demand Planetary Mapping
With these efficiencies, AlphaEarth empowers scientists, governments, and organizations to create detailed, consistent, on-demand maps for applications like crop monitoring, urban development, disaster response, and deforestation tracking without waiting for satellite passes.
The Role of Data Annotation in AlphaEarth
Behind AlphaEarth’s intelligence lies a critical foundation: high-quality data annotation
Data Sourcing & Ingestion
- Raw data types, such as satellite imagery (multi-spectral, radar), aerial/drone imagery, street-view data, LiDAR point clouds, GIS layers, and text-based geospatial metadata, are collected.
- Data pipelines pull feeds from providers such as Sentinel, Maxar, Landsat, Planet, and government open-data portals.
- Metadata alignment determines that imagery is tagged with georeferencing details (latitude, longitude, time, sensor type).
Preprocessing for Labeling
- Preprocessing begins with tiling by breaking massive satellite images into manageable, smaller patches.
- Next steps are normalization and cloud/shadow masking. Experts remove noise from weather effects before labeling.
Annotation Workflows
- Specialized geospatial labeling tools like CVAT, Labelbox, and ArcGIS AI are used for tasks such as object detection (buildings, roads, vehicles, ships), semantic segmentation (land cover, vegetation, water bodies), change detection (deforestation, construction, flooding), and 3D point cloud labeling for LiDAR and elevation data.
- Automated pre-labeling with weak AI models provides initial annotations that humans refine, increasing labeling speed by up to 400%.
Quality Assurance with Domain Experts
Domain experts such as cartographers, GIS specialists, environmental scientists, etc., are involved for such specialized tasks.
To ensure quality with multi-pass review, each project has at least two independent annotators plus a senior reviewer.
Data Management & Security
Secure cloud environments that ISO 27001 / SOC 2 certified; access control via VPN and RBAC (role-based access control).
Continuous Model Feedback
- Labeling companies run iterative annotation cycles as AlphaEarth or similar models are trained and deployed.
- Identify model weaknesses (false positives/negatives) in specific geographies or feature types.
- Feed corrected and edge-case data back into the training loop.
Support active learning—where the model flags uncertain areas for human labeling.
Industrial Benefits it Brings
