LEAP: Landsat Extended Acquisitions of the Poles Imaging Plan
Landsat Extended Acquisitions of the Poles (LEAP) imaging plan is a Landsat special request data collection program for Earth's polar regions that include Antarctica, Greenland, and Arctic sea ice geographies. The LEAP program includes Landsat 8 and Landsat 9 observatories that operationally acquire spaceborne images of all Earth's land surface and near-shore coastal environments. These images are acquired on a Worldwide Reference System-2, also called WRS-2. The WRS-2 is made up of paths and rows that define Landsat's imaged geography, and once acquired, are processed and discoverable in the U.S. Geological Survey's Landsat global data archive. The LEAP path-rows listed in the attached zipped data file represent image acquisitions for Antarctic, Greenland, and Arctic sea ice regions that are collected by special request during twilight conditions where the Sun's illumination angle is less than 5 degrees of elevation above the horizon.
