The Landsat Agreement: A Milestone in Earth Observation and Environmental Studies
The Landsat program is perhaps one of the most iconic and longest-running Earth observation programs in history. It all started in 1972 when NASA launched the first Landsat satellite into orbit, ushering in a new era of environmental monitoring, natural resource management, and ecosystem conservation. Since then, the Landsat program has provided unprecedented spatial and temporal data on land cover, land use, vegetation dynamics, water resources, and other vital environmental variables that are critical to understanding the complex interactions between human activities and the natural world.
However, the Landsat program would not have been possible without the Landsat agreement, which is a bilateral agreement between the United States and various international partners that provides free and open access to Landsat data for non-commercial use. The agreement was signed in 1984, and it has since been instrumental in promoting global collaboration and scientific exchange in the field of Earth observation and remote sensing.
Under the Landsat agreement, Landsat data are available to any user who agrees to abide by the terms and conditions set forth in the agreement. This means that researchers, government agencies, non-profit organizations, and other users can freely access and use Landsat data without having to pay any fees or royalties. The Landsat data are also provided with minimal processing, which allows users to customize the data to their specific needs and applications.
The Landsat agreement has had a profound impact on the field of Earth observation and environmental studies. It has enabled scientists and researchers to study and monitor environmental changes at a global scale, and to develop new tools and techniques for managing natural resources and ecosystems. It has also facilitated international cooperation and knowledge sharing, as researchers from different countries can access and analyze the same data, thereby promoting a common understanding of environmental issues and challenges.
Moreover, the Landsat agreement has also paved the way for the development of new applications and services that rely on Landsat data. For instance, the Global Forest Watch (GFW) platform, which was launched in 2014, utilizes Landsat data to provide near-real-time information on forest cover and deforestation rates around the world. Similarly, the WaterSMART program of the US Department of the Interior uses Landsat data to monitor water resources and drought conditions in different regions of the US, which helps to inform water management decisions.
In conclusion, the Landsat agreement is a landmark achievement in the field of Earth observation and environmental studies. It has paved the way for global collaboration and knowledge sharing, and has provided valuable data and insights into the complex interactions between human activities and the natural world. As we face ever-increasing environmental challenges and uncertainties, the Landsat program and the Landsat agreement will remain a vital tool and resource for environmental scientists, policymakers, and practitioners around the world.
