Explanation

Area of Interest​

The Area of Interest (AOI) defines the geographic region used for satellite data discovery and collection.

Earth Data Hub allows users to upload geospatial boundaries and select a field or polygon from the interactive map.

The selected AOI can be represented as either a bounding box or exact geometry.

Satellite Availability​

Before submitting a collection job, Earth Data Hub can check whether satellite imagery is available for the selected AOI and collection settings.

The available scenes are returned to Earth Data Hub and displayed to the user before job submission.

Tapis Collection Workflow​

Earth Data Hub converts the selected AOI and collection configuration into a GeoHarmonizer collection job and submits it through Tapis.
