We are interested in the following information about Provisional LPCS Products:

  • Which Provisional LPCS products were downloaded, and which services were applied (e.g., subset and reprojection of MODIS and VIIRS surface reflectance)
  • Any observed errors and/or artifacts in the delivered LPCS product(s)
  • Ease of navigating the LPCS access interface
  • Observations of production performance (e.g., were the products delivered in a timely manner?)
  • How the Provisional LPCS products or access interface can be improved
  • Any further details relevant to LPCS evaluation


Landsat represents the world's longest continuously acquired collection of space-based moderate-resolution land remote sensing data. Four decades of imagery provides a unique resource for those who work in agriculture, geology, forestry, regional planning, education, mapping, and global change research. Landsat images are also invaluable for emergency response and disaster relief.
