Open Access Landsat Coverage of the Earth at High Latitudes

Download Article:
Overlapping coverage of Landsat imagery at high latitudes is examined systematically and quantitatively. The Earth is separated into “row strips” aligned with the Landsat World Reference System (WRS), and the multi-scene coverage of Landsat imagery is divided into three types of areas: extended, missing, and overlap. Varying image orientation and narrowing row-strip width with increasing latitude are shown to have major impacts on these three areas. The dependencies of these coverage areas on skipping image collections from adjacent paths are calculated. This forms the basis for sampling strategies that can significantly reduce the number of images required to obtain full ground coverage at high latitudes. The calculations show that Antarctica can be covered with approximately one-third the total number of scene opportunities.
