Global Landsat Analysis Ready Data (ARD) Projection: Call for Response

Ahead of the Landsat Science Team (LST) meeting at USGS EROS in February, the USGS have requested input on the their efforts to scope and define ‘Global Landsat Analysis Ready Data (ARD)’. This will be one of the initial major tasks that the LST addresses in the first half of 2018 and a topic of discussion at the February LST meeting.
 
The USGS is moving forward on Global Landsat ARD and is currently in the process of scoping and drafting science and engineering requirements as part of Landsat 9 ground system development. As such, they have been working on a Global Landsat ARD pilot project to gain a deeper perspective on how choice of a global map projection will impact Landsat data quality and its users.
 
The following link https://landsat.usgs.gov/global-landsat-ard-projection-call will enable access to the Global Landsat ARD pilot project including a description of project objectives and data samples from 7 global test sites.
 
Please review the Global Landsat ARD information content and data samples and provide your perspective on such effort. Please provide your feedback on the following 4 questions (they are also listed near the end of the linked project description):

  1. Which of these projection parameters do you believe is the most suitable for the Landsat science user communities’ purpose?
  2. Will you be able to use the data ‘as is’ in any one of these projections, or will you need to apply further projection-related post-processing to use the data in your applications?
  3. Do you believe that one of these projection parameters in particular, removes the post-processing burden on your work?
  4. Do you believe that one of these projection parameters in particular, would add a post-processing burden to your work?

Please send your feedback to christopher.crawford.ctr@usgs.gov by 9 February 2018. Your early comments will set the stage for a Global Landsat ARD discussion at the February LST meeting.
