... The committee was asked to identify stakeholders and their data needs, recommend characteristics and critical program support areas expected of a sustained land imaging program, suggest critical baseline products and services derived from land imaging, and provide recommendations to facilitate the transition from NASA's research-based series of satellites to a sustained USGS land imaging program.2 The committee met with stakeholders, including the DOI, NASA, the Office of Science and Technology Policy, the National Oceanic and Atmospheric Administration, the U.S Department of Agriculture, the U.S. Forest Service, commercial data providers, and multiple land imaging data users, and analyzed earlier reports on the uses and value of moderate-resolution multispectral data.

... Such a program would • Develop a plan for a comprehensive, integrated program that capitalizes on the strengths of USGS and NASA, maintains current capability and the existing archive, and enhances the program as technology enables new imaging capabilities and data products; • Ensure acquisition of land imaging data continuously from orbital platforms and, periodically, from airborne platforms, to respond to the needs of producers and consumers of derived data products along with users who analyze imagery; • Establish partnerships with commercial firms and international land imaging programs to leverage enhanced capabilities; • Coordinate land imaging data buys across the U.S. government; and 3  Discussion of the history of the Landsat series of satellites is included in Chapter 1 in the section "A Chaotic History."
From page 3...
... Because future measurements will derive from both current and new technologies, new implementations of existing data products derived from a multispectral sensor should be cross-calibrateable with Landsat legacy products and be essentially interchangeable for scientific and operational purposes. To better meet these primary goals, the committee recommends that the program should • Systematically monitor users and uses of Landsat data so that the program can evolve with changing user requirements and • Consider alternative implementations that continue to enable the collection of global, moderateresolution data with the full range of spectral capabilities.
From page 4...
... Some incorporation of other types of data requires only better coordination across the government by increased sharing of existing or planned data. The committee recommends that the Sustained and Enhanced Land Imaging Program integrate measurements from commercial partners, spaceborne sensors recommended by the 2007 NRC report Earth Science and Applications from Space,4 and a variety of airborne sensors and acquisitions to enable analyses not possible using only moderate-resolution multispectral data.
From page 5...
... The Sustained and Enhanced Land Imaging Program should create an ambitious plan to incorporate opportunities to improve land imaging capabilities while at the same time increasing operational efficiency and reducing overall program cost. The program should consider a combination of the following to increase capabilities while reducing the costs for land imaging beyond Landsat 8: • Shift the acquisition paradigm by means of block buys and fixed-price contracting and by collaborating with commercial and international partners; • Streamline the process by which satellites and sensors are designed, built, and launched, using a single organizational unit approach (a collaborative team approach)
