Committee on Implementation of a Sustained Land Imaging Program; Space Studies Board; Division on Engineering and Physical Sciences; National Research Council
In 1972 NASA launched the Earth Resources Technology Satellite (ETRS), now known as Landsat 1, and on February 11, 2013 launched Landsat 8. Currently the United States has collected 40 continuous years of satellite records of land remote sensing data from satellites similar to these. Even though this data is valuable to improving many different aspects of the country such as agriculture, homeland security, and disaster mitigation; the availability of this data for planning our nation’s future is at risk.
Thus, the Department of the Interior’s (DOI’s) U.S. Geological Survey (USGS) requested that the National Research Council’s (NRC’s) Committee on Implementation of a Sustained Land Imaging Program review the needs and opportunities necessary for the development of a national space-based operational land imaging capability. The committee was specifically tasked with several objectives including identifying stakeholders and their data needs and providing recommendations to facilitate the transition from NASA’s research-based series of satellites to a sustained USGS land imaging program.
Landsat and Beyond: Sustaining and Enhancing the Nation’s Land Imaging Program is the result of the committee’s investigation. This investigation included meetings with stakeholders such as the DOI, NASA, NOAA, and commercial data providers. The report includes the committee’s recommendations, information about different aspects of the program, and a section dedicated to future opportunities.

The eighth satellite in NASA’s Earth-watching Landsat fleet will launch Monday, Feb. 11 from Vandenberg Air Force Base in California…. The joint program between NASA and the U.S. Geological Survey is the longest-running data record of Earth observations from space. …The Landsat program enables scientists to track major changes of Earth’s surface, including melting glaciers, urban explosion and the effects of natural disasters.

Science is increasingly driven by data, and spatial data underpin the science directions laid out in the 2007 U.S. Geological Survey (USGS) Science Strategy. A robust framework of spatial data, metadata, tools, and a user community that is interactively connected to use spatial data in an efficient and flexible way–known as a spatial data infrastructure (SDI)–must be available for scientists and managers to find, use, and share spatial data both within and beyond the USGS. Over the last decade, the USGS has conducted breakthrough research that has overcome some of the challenges associated with implementing a large SDI. This report is intended to ground those efforts by providing a practical roadmap to full implementation of an SDI to enable the USGS to conduct strategic science.

In light of swiftly changing technical landscapes and increasing uses of social networking, the USGS is exploring a new approach to the volunteer program, and is launching a project to test options for volunteer participation in providing data to The National Map. The project involves mapping man-made structures and facilities, such as schools and fire stations, in the state of Colorado. Using an internet mapping application, volunteers can help the USGS update The National Map by correcting or adding information about structures. “Even members of the public who can’t tell a sandstone from a rhyolite but have internet access can now help the USGS keep its popular maps up to date through our new experiment in crowd sourcing,” said USGS Director Marcia McNutt. “Correctly locating and identifying fire stations, police stations, schools, and hospitals not only makes USGS maps more useful, but can literally save a life.”
Over the past two decades, the USGS National Geospatial Program sponsored various forms of volunteer map data collection projects. Volunteers helped the USGS improve its maps during this period, by annotating paper maps, collecting data using GPS units, and submitting data using a web-based tool. However, in 2008, the volunteer mapping program was suspended as new methods for using volunteer data were being studied. In recent years, new web- and mobile-based technologies have made it easier to create, combine, and share maps. Recent events have shown how well these technologies support the rapid and relevant production of geographic information. If the Colorado pilot project is successful in attracting volunteers and capturing data for use in The National Map, the program may be expanded to other areas in the future. This project offers volunteers an opportunity to participate in providing data to The National Map and US Topo map products. For more information, interested Colorado volunteers can visit the National Map Corps website.

The U.S. Geological Survey (USGS) injected a bit of life into its aging Landsat 5 satellite, which has orbited Earth more than 150,000 times since its launch in 1984 and has been experiencing problems with its thematic mapper (TM) instrument. Engineers have been able to power-on a long-dormant data-collection instrument aboard the satellite—the multispectral scanner (MSS), which has been offline for more than a decade. USGS now is acquiring MSS data over the United States only. The news is significant, because USGS continues to work toward launch of an eighth Landsat satellite, meaning that data from current Landsat craft still are key to Earth-observing operations. Landsat 7, activated in 1999, continues to collect images worldwide. But, in 2003, Landsat 7 experienced a hardware failure that caused a 22-percent loss of data in every image. Meanwhile, the Landsat Data Continuity Mission (LDCM or Landsat 8), is scheduled for launch in January 2013.
