The Large Synoptic Survey Telescope will survey the entire sky for a decade from it's mountaintop perch in Chile, sweeping the sky every 3 nights, shooting two 3-gigapixel images per minute, adding up to a mind-boggling 20 terabytes of images to be processed every night. LSST's image processing pipelines will automatically analyze this stream of images, and will identify, and track moving objects. This article describes the MOPS (Moving Object Production System) pipeline, modeling using Enterprise Architect using ICONIX Process for Algorithmic Systems, as described in my book ICONIX Process Roadmaps.
LSST also is using Enterprise Architect for system engineering with SysML, and use case driven development for users of the telescope. It's a classic case of a large, complex, software intensive system, unifying UML and SysML development is the author's current research area of interest. LSST software and system models will be verified using Design Driven Testing (DDT) and DDT/Systems.
