Imagery - Landsat/Multispectral Landsat Image Service

Multispectral Landsat image service covering the landmass of the World. This service includes scenes from Landsat 8 and Global Land Survey (GLS) data from epochs 1990, 2000, 2005 & 2010 at 30 meter resolution as well as GLS 1975 at 60 meter resolution. GLS datasets are created by the United States Geological Survey (USGS) and the National Aeronautics and Space Administration (NASA) using Landsat images. This service can be used for mapping and change detection of urban growth, change of natural resources and comparing Landsat 8 imagery with GLS data. Using on-the-fly processing, the raw DN values are transformed to scaled (5000 - 55000) apparent reflectance values and then different service based renderings for band combinations and indices are applied. The band names are in line with Landsat 8 bands; GLS data band names are mapped along the same lines.
