Nature today published a story about a Department of Interior committee studying the possibility of charging fees for data from the Landsat satellite program, data that are currently available for free. The first Landsat satellite was launched in 1972, with 6 additional satellites launched since then. The latest was Landsat 8, launched in 2013, while Landsat 9 is scheduled for launch in late 2020. Landsat satellites have provided continuous Earth observations for the last 46 years (!!!!), an invaluable and unmatched record for recording changes on the Earth’s surface. The number of applications of Landsat data is astounding, including monitoring forestry activity (forest harvest and regrowth), agricultural productivity, monitoring urban sprawl, quantifying changes in surface water extent in response to flooding or drought, assessing the impacts of natural disasters, mapping geologic landforms, and a host of other uses. As the Nature article notes, a 2013 committee commissioned to assess the economic costs and benefits of the Landsat program found that while the program costs the US government approximately $80 million a year, economic benefits for the country are staggering…well over $2 billion per year.
Management of Landsat has changed over the years, but USGS and NASA are the two Federal agencies currently managing the program. Until 2008, the data came at a cost to the user...a cost that historically could be quite high. A disastrous attempt to semi-privatize Landsat data distribution in the 1990s led to costs for each Landsat “scene” (an area approximately 115 x 115 miles) of up to $4,000! While highly valuable data for a number of applications, the high cost was a major roadblock for usage of the data. In 2008, the USGS made the decision to begin distributing the data free of charge…and usage of Landsat data grew exponentially. Before the policy change, USGS distributed a mere ~50 scenes per day. Once the data were made freely available, usage jumped more than 100-fold, with thousands of Landsat scenes downloaded per day. Having freely available data from the world’s premiere long-term observation platform of the Earth’s surface has since transformed Earth science. Applications once hindered by data costs were now free to tap into the entire Landsat database.
The Nature story notes that under the current administration, the committee is considering again re instituting a fee for access to Landsat. Given the other actions of Secretary of the Interior Ryan Zinke, EPA Administrator Scott Pruitt, and other administration officials with roles overseeing environmental science, it’s easy to speculate as to the real purpose of the committee. DOI, EPA, NOAA, and other scientific agencies and programs in the Federal government have been targeted for draconian reductions by the Trump industry. Elimination of environmental science and privatization of traditional government activities has been a major focus of this administration. My own personal interpretation…this is a move to 1) curtail the vast array of environmental monitoring and analysis that’s occurred since Landsat data were made freely available, 2) bow to the will of industry lobbyists who wish to continue the push towards privatization of Earth observations and increase corporate profits, and 3) eventually extricate the US government from running the Landsat program and other similar Earth observation systems.
Any truly unbiased analysis of the Landsat program would label the 2008 move to freely available data as a smashing success, both in terms of economics and the scientific benefits. Returning to the 1990s and charging high fees for Landsat data access would result in an immediate, sharp decline in environmental and economic applications that use the data. Given that the one overarching theme of the Trump administration is “corporate profit above all else”, it’s impossible to view this potential move with anything other than a highly cynical eye.
