  • Trends in Space Commerce
    Foreword from the Secretary of Commerce As the United States seeks opportunities to expand our economy, commercial use of space resources continues to increase in importance. The use of space as a platform for increasing the benefits of our technological evolution continues to increase in a way that profoundly affects us all. Whether we use these resources to synchronize communications networks, to improve agriculture through precision farming assisted by imagery and positioning data from satellites, or to receive entertainment from direct-to-home satellite transmissions, commercial space is an increasingly large and important part of our economy and our information infrastructure. Once dominated by government investment, commercial interests play an increasing role in the space industry. As the voice of industry within the U.S. Government, the Department of Commerce plays a critical role in commercial space. Through the National Oceanic and Atmospheric Administration, the Department of Commerce licenses the operation of commercial remote sensing satellites. Through the International Trade Administration, the Department of Commerce seeks to improve U.S. industrial exports in the global space market. Through the National Telecommunications and Information Administration, the Department of Commerce assists in the coordination of the radio spectrum used by satellites. And, through the Technology Administration's Office of Space Commercialization, the Department of Commerce plays a central role in the management of the Global Positioning System and advocates the views of industry within U.S. Government policy making processes. I am pleased to commend for your review the Office of Space Commercialization's most recent publication, Trends in Space Commerce. The report presents a snapshot of U.S.

  • Moderate Resolution Remote Sensing Alternatives: a Review of Landsat-Like Sensors and Their Applications
    Journal of Applied Remote Sensing, Vol. 1, 012506 (9 November 2007) Moderate resolution remote sensing alternatives: a review of Landsat-like sensors and their applications Scott L. Powella*, Dirk Pflugmacherb, Alan A. Kirschbaumb, Yunsuk Kimb, and Warren B. Cohena a USDA Forest Service, Pacific Northwest Research Station, Corvallis Forestry Sciences Laboratory, Corvallis, OR, 97331, USA b Oregon State University, Department of Forest Science, Corvallis, OR, 97331, USA * Corresponding Author USDA Forest Service, Pacific Northwest Research Station, Corvallis Forestry Sciences Laboratory, Corvallis, OR, 97331, USA [email protected] Abstract. Earth observation with Landsat and other moderate resolution sensors is a vital component of a wide variety of applications across disciplines. Despite the widespread success of the Landsat program, recent problems with Landsat 5 and Landsat 7 create uncertainty about the future of moderate resolution remote sensing. Several other Landsat- like sensors have demonstrated applicability in key fields of earth observation research and could potentially complement or replace Landsat. The objective of this paper is to review the range of applications of 5 satellite suites and their Landsat-like sensors: SPOT, IRS, CBERS, ASTER, and ALI. We give a brief overview of each sensor, and review the documented applications in several earth observation domains, including land cover classification, forests and woodlands, agriculture and rangelands, and urban. We conclude with suggestions for further research into the fields of cross-sensor comparison and multi-sensor fusion. This paper is significant because it provides the remote sensing community a concise synthesis of Landsat-like sensors and research demonstrating their capabilities. It is also timely because it provides a framework for evaluating the range of Landsat alternatives, and strategies for minimizing the impact of a possible Landsat data gap.
