The National Land Imaging Program NLIP Ensuring Operational

The National Land Imaging Program (NLIP) “Ensuring Operational Land Imaging Continuity in the 21 st Century” Las Vegas - May 1973 FGDC Coordination Group Meeting September 4, 2008 Ray Byrnes, Liaison for Satellite Missions USGS Land Remote Sensing Program U. S. Department of the Interior U. S. Geological Survey Las Vegas - February 2006

National Land Imaging Program § In December 2005, the President’s Science Advisor stated: “It remains the goal of the U. S. Government to transition the Landsat program from a series of independently planned missions to a sustained operational program…” § Throughout 2006, an OSTP-appointed interagency working group developed a plan, subsequently released by the White House in August 2007 See interagency working group report at http: //ostp. gov/cs/nstc under “Documents and Reports, 2007” U. S. Geological Survey Department of the Interior 2

Why NLIP? § § § No long-term U. S. commitment for providing Landsat-like data. § Landsat has been a series of independent missions, funded in an ad hoc manner. § No U. S. agency has responsibility to meet U. S. operational requirements. § Advancement of land imaging technology and applications has been delayed or disrupted. No U. S. commercial alternative. § Landsat commercialization has failed twice. § U. S. commercial and foreign systems can augment, but not replace Landsat. No resources to sustain an operational land imaging program for the U. S. § No satellite funding or plans beyond Landsat Data Continuity Mission (LDCM)/Landsat 8. U. S. Geological Survey Department of the Interior 3

Interagency Working Group Recommendations § The U. S. must commit to continue the collection of moderate-resolution land imagery. § The U. S. should establish and maintain a core operational capability to collect moderate-resolution land imagery through the procurement and launch of a series of U. S. -owned satellites (Landsat 9 and beyond). § The U. S. should establish the National Land Imaging Program, hosted and managed by the Department of the Interior, to meet U. S. civil land imaging needs. U. S. Geological Survey Department of the Interior 4

Federal Government Responsibilities § National Land Imaging Program (NLIP) Mission: § To serve the Nation by acquiring and providing operational land imaging capabilities and applications to support U. S. economic, environmental, foreign policy, and security interests. § Federal Government to run an operational program to: § Coordinate a Federal Land Imaging Council composed of data users and other interested agencies and a (FACA) Land Imaging Advisory Committee; § Gather U. S. land imaging requirements (e. g. data needs); § Manage the acquisition of U. S. land imaging systems and data; § Coordinate acquisition and data distribution plans with U. S. industry, foreign governments, and foreign commercial firms; § Ensure timely data delivery to all users; § Permanently archive these data for future generations; § Develop new applications for Federal, State, local and tribal governments; and § Investigate and develop new remote sensing technology to meet land imaging requirements. § Above all else, ensure availability, access, and ease of use of land imaging data for the Nation. U. S. Geological Survey Department of the Interior 5

Government-owned satellites. § Receive data downlinks from domestic or § § § international government or commercial partners. Purchase global or regional satellite or aerialplatform data sets. Consolidate Landsat data holdings of International Cooperators. Ingest selected “purged” commercial or government data sets. U. S. Geological Survey Department of the Interior 7

Landsat Data Policy Update § § Updated Landsat data policy was approved in January 2008. § Located at: http: //ldcm. usgs. gov/pdf/Landsat_Data_Policy. pdf Policy Goals § Extend the principles of the Landsat 7 Data Policy established in Section 5615 of U. S. Code Title 15, Chapter 82 to Landsats 1 -7, LDCM, and future U. S. -owned moderate resolution land-image data sets. § The goals ensure § Unenhanced data are available to all users at no more than the Cost § § § of Fulfilling User Requests (COFUR). Timely delivery of unenhanced data to civilian, national security, commercial, and foreign users. U. S. retains ownership of all unenhanced data generated by the Landsat series of satellites. Development of the commercial market for remote sensing data. U. S. Geological Survey Department of the Interior 8

Landsat Ground Station Historical Perspective § § § Over the past 35 years, over 50 ground stations have been configured to receive Landsat data. Currently, there are 24 ground stations around the world that are configured to operationally receive Landsat data (19 currently active). Beyond the current stations, there are 9 historical collection sites operated by 7 organizations that we believe could have a significant, unique historical archive. U. S.

Landsat Global Archive Consolidation § The USGS is evaluating the process, cost and relative merit for consolidating a copy of the global archive of historical Landsat imagery. § § § § § There is growing concern about the state of historical archives, especially at inactive stations where we have no active contacts. At this point, it is not known what the historical archive extent is. There is an increasing interest from user community and USGS/NASA for more frequent surveys. New tools such as Large Area Scene Selection Interface (LASSI) are being developed and made available to support large scale scene selections/data mining. A consolidated archive would better support/facilitate global change analysis and assessment. Determine the location, extent and condition of the historical Landsat archives around the world. Generate a list of the instrument (RBV, MSS, TM, ETM+), data format and media type at each location. Assess the equipment, software, logistics and level of effort necessary to acquire, ingest, process and archive the data. Develop an estimated cost and schedule for project. U. S.
