Geospatial Annotation Platform FAQs
Answers about satellite and aerial image annotation, remote sensing, large geospatial rasters, land-cover segmentation, coordinates, ontologies, quality workflows, and model integration in Unitlab.
Talk with the Unitlab teamWhat geospatial annotation types does Unitlab support?+
Unitlab supports bounding boxes, segmentation masks and brushes, polygons, skeletons, lines and polylines, points and keypoints, cuboids and 3D boxes, relations, class properties, and Item Properties. Teams define labels and rules in a reusable ontology for consistent geospatial training data.
Geospatial annotation documentationHow can AI assist geospatial image labeling?+
Use built-in foundation models or bring your own model to generate visual predictions for supported image annotation types. Annotators review and refine model output so human approval remains part of the quality process.
Auto-labeling documentationCan Unitlab support large aerial images and precise visual inspection?+
Yes. Unitlab applies its visual annotation workspace to aerial imagery so teams can inspect small structures while maintaining broader image context. Use boxes, polygons, masks, polylines, and keypoints as appropriate for each image.
Image annotation documentationHow do ontologies and properties work in geospatial annotation?+
Reusable ontologies define classes, attributes, Item Properties, and relations. For example, a Building can have Type and Condition attributes, a Road can have Type and Surface attributes, and the two objects can be connected with an adjacent-to relation.
Properties and relations documentationHow does Unitlab manage geospatial annotation quality and review?+
Configurable workflows route geospatial tasks through annotation, review, rework, and approval. Instructions, assignments, comments, issues, annotation history, dataset versions, and releases keep quality decisions traceable for individual experts and enterprise teams.
Annotation and review documentationCan teams use their own AI models for geospatial pre-labeling?
Yes. Unitlab can bring custom models into the annotation workflow to generate pre-labels and predictions. Annotators review and correct model output instead of starting from zero, while human approval remains part of the governed quality process.
Model integration documentationCan Unitlab curate, annotate, and version geospatial datasets in one platform?
Yes. Teams can curate geospatial data with metadata filters, semantic search, embeddings, similarity, and outlier discovery, then annotate selected samples, review results, and publish controlled dataset versions for reproducible AI development.
