Geospatial Library (GL) 1 SCOPE This source specification establishes the basis for the performance, design, development, and test requirements for a Geospatial Library. This Geospatial Library accepts requests for imagery information, determines the best way for the system to respond to the request, and then provides the requested information. In the process of acquiring the requested information, the system may generate tasking orders for a set of imagery data collectors. The mission of the Geospatial Library is to provide management of a system of Imagery collectors, from the acceptance of customer requests, through scheduling the collectors, to delivery of the imagery products to the customers. 2 APPLICABLE DOCUMENTS The applicable documents for the Geospatial Library program are: Geospatial Library source specification (this document) ISO 15288:2015 (System life cycle processes) 3 OPERATIONS 3.1 The Geospatial Library shall provide continuous real ‐ time support to the customers and the collection systems. 4.3 The system shall be unavailable no more than a total of ten minutes per month. 4 SPECIFIC REQUIREMENTS 4.1 The system shall accept information requests from certified customers. 4.2 The system shall retain an inventory of previously collected images/products and provide them to users, if appropriate. 4.3 The system shall control multiple image collectors and multiple types of image collectors. 4.4 The system shall be staffed at a maximum of 25 personnel on any shift. 4.5 The system shall provide feedback on the customer's request within twenty ‐ four hours. 4.6 The system shall provide a means of prioritizing the customer's requests. 4.7 The system shall monitor and assess its own performance.

Capturing and Decomposing Originating Requirements 1) Capture the source document 2) Extract top-level or parent source requirements capturing source attributes (paragraph title, paragraph number, origin, etc.) 3) Provide traceability from the source document to the parent originating requirements 4) Decompose composite source requirements being careful not to change the meaning 5) Provide traceability from each parent requirement to its children 6) Continue the decomposition of requirements into “children” until each leaf-level requirement is a single, verifiable statement
