  • The Earth Observer. July
    National Aeronautics and Space Administration The Earth Observer. July - August 2012. Volume 24, Issue 4. Editor’s Corner Steve Platnick obser ervth EOS Senior Project Scientist The joint NASA–U.S. Geological Survey (USGS) Landsat program celebrated a major milestone on July 23 with the 40th anniversary of the launch of the Landsat-1 mission—then known as the Earth Resources and Technology Satellite (ERTS). Landsat-1 was the first in a series of seven Landsat satellites launched to date. At least one Landsat satellite has been in operation at all times over the past four decades providing an uninter- rupted record of images of Earth’s land surface. This has allowed researchers to observe patterns of land use from space and also document how the land surface is changing with time. Numerous operational applications of Landsat data have also been developed, leading to improved management of resources and informed land use policy decisions. (The image montage at the bottom of this page shows six examples of how Landsat data has been used over the last four decades.) To commemorate the anniversary, NASA and the USGS helped organize and participated in several events on July 23. A press briefing was held over the lunch hour at the Newseum in Washington, DC, where presenta- tions included the results of a My American Landscape contest. Earlier this year NASA and the USGS sent out a press release asking Americans to describe landscape change that had impacted their lives and local areas. Of the many responses received, six were chosen for discussion at the press briefing with the changes depicted in time series or pairs of Landsat images.

  • Landsat Data: Community Standard for Data Calibration
    LANDSAT DATA: COMMUNITY STANDARD FOR DATA CALIBRATION A Report of the National Geospatial Advisory Committee Landsat Advisory Group October 2020 Landsat Data: Community Standard for Data Calibration October 2020 LANDSAT DATA: COMMUNITY STANDARD FOR DATA CALIBRATION Executive Summary Landsat has become a widely recognized “gold” reference for Earth observation satellites. Landsat’s extensive historical record of highly calibrated data is a public good and exploited by other satellite operators to improve their data and products, and is becoming an open standard. However, the significance, value, and use case description of highly calibrated satellite data are typically not presented in a way that is understandable to general audiences. This paper aims to better communicate the fundamental importance of Landsat in making Earth observation data more accessible and interoperable for global users. The U.S. Geological Survey (USGS), in early 2020, requested the Landsat Advisory Group (LAG), subcommittee of the National Geospatial Advisory Committee (NGAC) to prepare this paper for a general audience, clearly capturing the essence of Landsat’s “gold” standard standing. Terminology, descriptions, and specific examples are presented at a layperson’s level. Concepts emphasize radiometric, geometric, spectral, and cross-sensor calibration, without complex algorithms. Referenced applications highlight change detection, time-series analysis, crop type mapping and data fusion/harmonization/integration. Introduction The National Land Imaging Program leadership from the U.S. Geological Survey (USGS) requested that the Landsat Advisory Group (LAG), a subcommittee of the National Geospatial Advisory Committee (NGAC), prepare a paper that accurately and coherently describes how Landsat data have become widely recognized as a radiometric and geometric calibration standard or “good-as-gold” reference for other multi-spectral satellite data.

The purpose of ALI was to validate in space new technologies that could be utilized in future Landsat satellites, resulting in significant economies of mass, size, power consumption, and cost, and in improved instrument sensitivity and image resolution. The sensor performance on orbit was verified through the collection of high-quality imagery of the earth as seen from space. ALI was launched onboard the Earth Observing 1 (EO-1) satellite in November 2000 and inserted into a 705 km circular, sun-synchronous orbit, flying in formation with Landsat 7. Since then, ALI has met all its performance objectives and continues to provide good science data long after completing its original mission duration of one year.

    National Aeronautics and Space Administration The Earth Observer. May - June 2017. Volume 29, Issue 3. Editor’s Corner Steve Platnick EOS Senior Project Scientist At present, there are nearly 22 petabytes (PB) of archived Earth Science data in NASA’s Earth Observing System Data and Information System (EOSDIS) holdings, representing more than 10,000 unique products. The volume of data is expected to grow significantly—perhaps exponentially—over the next several years, and may reach nearly 247 PB by 2025. The primary services provided by NASA’s EOSDIS are data archive, man- agement, and distribution; information management; product generation; and user support services. NASA’s Earth Science Data and Information System (ESDIS) Project manages these activities.1 An invaluable tool for this stewardship has been the addition of Digital Object Identifiers (DOIs) to EOSDIS data products. DOIs serve as unique identifiers of objects (products in the specific case of EOSDIS). As such, a DOI enables a data user to rapidly locate a specific EOSDIS product, as well as provide an unambiguous citation for the prod- uct. Once registered, the DOI remains unchanged and the product can still be located using the DOI even if the product’s online location changes. Because DOIs have become so prevalent in the realm of NASA’s Earth 1 To learn more about EOSDIS and ESDIS, see “Earth Science Data Operations: Acquiring, Distributing, and Delivering NASA Data for the Benefit of Society” in the March–April 2017 issue of The Earth Observer [Volume 29, Issue 2, pp. 4-18]. continued on page 2 Landsat 8 Scenes Top One Million How many pictures have you taken with your smartphone?

  • 8 7 Outcomes Towards
    GEO Forest Carbon Tracking Task Draft section to the CEOS High Profile Publicationi 1. Forests, CO2 and biodiversity Deforestation, degradation and peat fires represent up to 20% of the global anthropogenic CO2 emissions according to the Intergovernmental Panel on Climate Change (IPCC). Compared with other measures, reducing deforestation and forest degradation is a relatively straight-forward action to rapidly reduce global CO2 emissions, which in addition would bring positive side-effects in terms of environmental conservation and protecting biological diversity. This is the essence of the UNFCCC programme on Reducing Emissions from Deforestation and Forest Degradation (REDD+), which aims to engage developing countries, in particular in the tropical zone, to reduce emissions from deforestation and forest degradation, manage the role of conservation and sustainable management and enhance their forest carbon stocks. One of the main challenges to the inclusion of forest protection in the post-Kyoto framework has been the question about the capacity to consistently monitor the vast areas required and to establish reliable systems for national measuring, reporting and verification (MRV) of forest carbon stocks and their changes. Both technology and political willingness have matured and the COP-15 Copenhagen Accord called for the “immediate establishment of a mechanism including REDD+”, to be in operation by 2013. Furthermore, COP-15 draft decision 1(d) requests developing country Parties to establish robust and transparent national forest monitoring systems using a combination of remote sensing and ground-based forest carbon inventory approaches. The GEO Forest Carbon Tracking Task was established to provide satellite-based observation support to countries on the path towards the establishment of sovereign national MRV systems, forming a global network of MRV systems that comply with IPCC guidelines and support REDD+.

  • 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.
