Semantic segmentation labeling
Groundwork supports satellite and aerial feature extraction for deep learning. Annotate imagery using our easy freehand lasso and polygon labeling tools.

Object detection in aerial imagery
Object detection in aerial imagery presents unique challenges around resolution, orientation, and noise. Groundwork supports freehand contours and bounding for labeling complex training data.

Image classification
Groundwork breaks large geospatial imagery into smaller pieces, to make creating remote sense training data from satellite and other aerial imagery easy.

Cloud-native architecture
All imagery is stored as cloud optimized GeoTiffs and labels are stored as GeoJSON. Exported data is represented as a SpatioTemporal Asset Catalog.
We offer managed annotation services for satellite, drone, and other aerial imagery. Our R&D team can also work with you to train custom computer vision models that meet your needs. Learn more about our services.
