Abstract: A method and a computer system for providing a federated wide area motion imagery (WAMI) collection service are provided. The method may include collecting WAMI collection metadata by issuing a request for retrieving WAMI collection metadata from one WAMI collection service (CS) and storing the response. The WAMI CS may run at a geographic location, and WAMI data may be collected and stored there. The WAMI collection metadata may indicate where the WAMI data is stored, and it may be transmitted to the federated WAMI CS. The method may further include organizing the WAMI collection metadata in a tree structure or directed acyclic graph (DAG). A request for accessing the stored WAMI data may then be received from a client using the stored WAMI collection metadata. Access may be provided to the geographic location of the WAMI CS to retrieve a portion of the WAMI data.

Abstract: This disclosure relates to WAMI discovery, specifically including: issuing a first request to a WAMI federated collection service (FCS) to retrieve WAMI collection metadata, the WAMI FCS being in communication with a WAMI collection service (CS), each WAMI CSs being in communication with a location where WAMI data is stored; receiving a response in a first format from the WAMI FCS; translating the received WAMI collection metadata from the first format into another format; issuing a second request to the WAMI FCS to access WAMI data in the other format; and retrieving in response to the second request, the WAMI data in the other format from the location that corresponds to a network link.

Abstract: This disclosure provides a federated wide area motion imagery (WAMI) collection service (CS) by: receiving an alert from a WAMI alert-service (A) respectively associated with a WAMI CS regarding any updates to WAMI data served by the WAMI CS at the federated WAMI CS, the WAMI CS providing WAMI collection metadata; issuing a request to the WAMI A associated with the WAMI CS to read information on what is updated; receiving a response from the WAMI A at the federated WAMI CS, the response comprising tree nodes corresponding to WAMI collection metadata that are updated by the WAMI CS; issuing a subsequent request to the WAMI CS from the federated WAMI CS to retrieve the WAMI collection metadata from the WAMI CS corresponding to the collection tree nodes that are updated; receiving a response including the WAMI collection metadata from the WAMI CS; and storing the received WAMI collection metadata in cache of the federated WAMI CS of the system.
