Abstract

The Mission Operations Center (MOC) at the Earth Resources Observation Systems (EROS) Data Center in Sioux Falls, SD manages the Landsat 7 Image Assessment System (IAS) and Level 1 Processing System (LPGS). Both systems process Level 0 non-radiometric corrected Landsat 7 data into Level 1 radiometric and geometric corrected products. Production of products from Level O to Level 1 is the primary function of the LPGS. The IAS performs image assessment and quality assurance on selected data stored in the Landsat 7 data archive. Before launch of the Landsat 7 satellite in 1999, Computer Science Corporation built the IAS and LPGS as two independent systems. Recently, the Landsat 7 Mission Management Office (MMO) program management chartered a project to consolidate parts of each system in an effort to lower overall maintenance and improve efficiency. In November 2001, MMO program management signed a formal project plan. The project plan identifies the Level 1 team and outlines the initial scope and deliverables of the consolidation. The consolidation consists of business process analysis, database analysis, hardware consolidation, and a significant amount of software changes. The hardware consolidation activity involves an analysis of the existing hardware followed by combining two systems into one. Savings of $26,000 the first year and $19,000 thereafter are realized from this activity.
